FORENSIC PHOTOGRAPHY AND ITS IMPORTANCE.

FORENSIC PHOTOGRAPHY AND ITS IMPORTANCE

Several careers and creative opportunities are available in the field of creativity. With forensics software, image creators can also work in the legal and law enforcement sectors. Forensics software is used to gather trustworthy visual evidence of the incidents in cases of death, whether caused by homicides, accidents, or other factors that need clarification.

A photographer with this speciality works on forensic software and law enforcement cases. As you can expect, forensic photography calls for a great deal of responsibility and extreme seriousness. The following elements must be present in this speciality’s work of lens creatives.

Use panoramic photography to connect the subject to its surroundings.
In-depth shots of the participants’ objects or individuals.
To comprehend, for instance, a murder scene, eliminate or enhance shadows as necessary.
Identity cards include the date, file, name, age, photographer’s name, etc.
Telephoto lenses, UV filters, and other equipment can be used to acquire complementary images (if required).

How should a judge decide whether photographs from video surveillance are admissible?

Here are some points that the judge can consider while reviewing whether the photographs from video surveillance are admissible.

Realistic images are required – The only way to guarantee that photos accurately depict a fact or subject and that no improvements, alterations, or secondary effects have been applied that could mislead the points is through image authentication. Whether or not the illumination is sufficient to take sharp photographs day and night will be a significant factor in this. Always collect and save the original copy as soon as you can. A claim regarding the veracity of the video footage will be strengthened if witnesses see the events without camera evidence. Even if we think something qualifies as evidence, a judge might disagree. Thus:

Examine the monitoring settings for pixelated images.
Ensure the equipment is configured to record enough frames per second by testing video playback (FPS).
Use image enhancement software for quality.
Plan routine system and camera maintenance.
Verify that the display settings, date, and time are accurate.

Excellent camera resolution-Facial recognition is more reliable when using high-resolution photos. Remember that photoshop might make evidence in an image authentication process inadmissible. Your footage will express more detail if the resolution is sharper.

The significance of camera positioning-Considers whether placing the camera at an exceptionally high position will allow us to accurately capture the faces of people of various heights. The ideal option is to set up many cameras, which will also have the added benefit of addressing any problems brought on by device failure. Putting the camera as close to eye level as possible is effective. The likelihood of obtaining solid and admissible evidence increases with the number of photographs from various perspectives that may be gathered. Install the cameras in strategic locations, including the entrances and exits. Finding the ideal place and maximizing coverage for each device can be done with a floor or building plan. It is crucial to test the camera after positioning it. Ensure that the main halls, exits, and entrances all have unobstructed sightlines. Make sure nothing is in the way of your vision, see how the lighting changes throughout the day and night, etc. This is an excellent method to find issue areas and get to work on solutions.

Luminous position –It’s important to research how individuals will seem when fully illuminated from the front or at various times of the day. The depth of field will increase as more light is added. The footage will be sharper and more likely to be admitted into evidence if the depth of field is larger.

Not every picture or video your CCTV system records is ideal for the forensic investigation of a crime scene. To assist you in authenticating and improving your footage, you must get a CCTV video enhancer. Use Cognitech video investigator as your forensic image enhancement program, as we strongly advise.

PROS AND CONS OF USING PHOTOGRAMMETRY SOFTWARE FOR 3D MODELS

PROS AND CONS OF USING PHOTOGRAMMETRY SOFTWARE FOR
3D MODELS

Photogrammetry, an amalgamation of art and science, involves the process of measuring from photographs (photograms) and has been in existence since the Second World War, owing to the critical role of photography in remote sensing.
Another technology for capturing the geometry of an object and generating a 3D model is photogrammetry. Unlike 3D scanning, this method employs photographs rather than light to gather data. To construct a 3D model, a camera, a computer, and specialized software are all required for this technology.

A Quick View Of Photogrammetry Software

Photogrammetry software is a specialized type of software that is used to process and analyze photographs taken of an object or a scene in order to create a 3D model or map. This software utilizes algorithms and computational methods to identify and match features in multiple photographs of the same object or scene, and then uses these matches to calculate the position and orientation of the camera when each photograph was taken.
The software then combines these calculations to create a 3D point cloud or mesh, which can be further processed to create a 3D model that can be viewed and manipulated on a computer. Photogrammetry software typically includes a range of tools and features for processing, editing, and optimizing the resulting 3D model, including tools for texture mapping, mesh editing, and exporting the model to various file formats.

Cognitech’s photogrammetry software is designed specifically for forensic and law enforcement agencies, and it enables the creation of 3D models from photographs taken at a crime scene or accident site. The software uses advanced algorithms to reconstruct a 3D model of the scene, which can then be used for further analysis, such as measuring distances, angles, and volumes.
AutoMeasure is an exclusive component of the Tri-Suite64 software bundle and is the sole Automatic Forensic Photogrammetry Software globally that can produce precise bio-metric measurements, such as the suspect’s height, and crime scene measurements, using surveillance videos and photographs. Automeasure 64 is widely regarded as the optimal photogrammetry software for reconstructing crime scenes, with exclusive features that are patented and unique to this software.

Advantages And Disadvantages Of Using Photogrammetry For 3d Models

PROS

Non-Contact Method: Photogrammetry is a non-contact method of measurement, which means that the object being measured doesn’t have to be touched or disturbed during the process. This is particularly useful for fragile or valuable objects, or for objects that are difficult to access.
Wide Range of Applications: Photogrammetry can be used in a wide range of applications, from creating 3D models of buildings, landscapes, and cultural heritage sites to generating digital terrain models and orthophotos for use in geographic information systems (GIS).
High Accuracy: Photogrammetry software can achieve high levels of accuracy, often within a few millimeters, making it suitable for applications such as engineering, architecture, and surveying.
Fast and Cost-Effective: Photogrammetry is often faster and more cost-effective than traditional measurement methods, as it requires only a camera and specialized software. This can make it a useful tool for small businesses and individuals who need to create 3D models but may not have access to expensive equipment or expertise.
Can Capture Large Areas: Photogrammetry can capture large areas quickly and easily, which makes it suitable for creating 3D models of landscapes and other outdoor environments. It is also useful for aerial surveys and mapping, as drones or aircraft can be used to capture images of large areas from above.

CONS

Image Quality: The accuracy and quality of the 3D model produced by photogrammetry can be affected by the quality of the input images. Poor lighting conditions, motion blur, or low-resolution images can result in a lower quality 3D model.
Processing Time: Creating a 3D model using photogrammetry can require a significant amount of time and computational resources, depending on the complexity of the object and the number of images used. This can be a disadvantage when time is a critical factor.
Expertise and Skill: Using photogrammetry software requires some degree of expertise and skill to achieve accurate and high-quality results. It can be challenging to learn and master, and may require specialized training or experience.

Overall, photogrammetry software is a versatile and cost-effective method for creating 3D models with high accuracy, making it a useful tool for a wide range of applications, but it also requires careful consideration of the potential limitations and drawbacks.

CCTV ENHANCEMENT FOR FORENSIC PURPOSES

Currently, there are more than 5 million CCTV cameras in the UK, and as costs continue to decline, there will be even more cameras. Every high street has surveillance cameras, and doorbell cameras and home security systems are gradually replacing traditional household items as everyday items. CCTV is a crucial part of a secure workplace.
Because so much of daily life is captured on camera, CCTV footage is crucial as digital forensics evidence in the criminal justice system. However, CCTV video evidence is typically of low quality and needs to be upgraded and studied before it can be used effectively in court. CCTV footage can be used in casework for a variety of legal concerns, including traffic accidents and homicides, due to the ubiquitous deployment of these cameras.

A more realistic portrayal of the events can be achieved by improving the quality of the CCTV camera footage. Modern video forensics techniques can eliminate blur and pixilation to improve clarity and highlight details, making video evidence more persuasive in court. Modern technology is combined with expert analysis to help defence attorneys better understand how discoveries may impact their case.

20 years of Evolution in Cognitech VideoActive: From Patented Lossless Video Acquisition to Patented Automatic Video Sorting, Searching, and Indexing

Here is the next part of the previous blog series, Thanks again for reading the blog…

ForensicFriday

Continuing with our previous discussion on the pioneering technological breakthrough achieved by developing Cognitech VideoActive, the session aims to explain the essential features of this Real-Time Video Forensics Software as wells as Crime Scene Reconstruction Software.

With the exponentially increased use of CCTV cameras across all functions and departments, it becomes difficult for the security personnel to monitor and ascertain the situation distributed through multiple cameras accurately. This is where Real-Time video analysis finds its natural use.

Patented Automatic Demultiplexing

Another application that is naturally suited for Real-Time implementation is Demultiplexing, which converts intertwined multiple camera video source streams, such as multiplexed CCTV footage, into individual digital camera channels that can be stored, processed or viewed, individually or together. The multiplexed videos are still to be found with the analog recording system. Automatic demultiplexing intelligently determine how to separate demultiplexed frames into individual camera channels with no human interaction for any number of channels. Manual demultiplexing, on the other hand, sorts demultiplexed video according to user-defined key-frames.

The first-ever scientific publication on Demultiplexing and specifically Automatic Demultiplexing through algorithm was published by Cognitech’s scientists: “Software-based universal demultiplexing: threshold-free energy minimization approach”

Author(s): Frederic Guichard; Alexander Litz; Lenny I. Rudin; Ping Yu

2001, SPIE Proceedings Vol. 4232 Conference on

Enabling Technologies for Law Enforcement and Security,

The original idea of Automatic Demultiplexing was to compare the streaming video frames and group them accordingly to similarity criteria. These similarity criteria can be as simple as correlation measure between frames, which assumes that frames do mot have dynamic changes, like moving vehicles or walking people.

Cognitech scientists improved the demultiplexing algorithm further to account for scenes with constant changes present, like casino floor and freeway traffic (published in Advanced Video and Signal Based Surveillance, 2005. AVSS 2005. IEEE Conference

“Meaningful automatic video demultiplexing with unknown number of cameras, contrast changes, and motion.”Jose Luis Lisani, Lenny Rudin, Pascal Monasse, Jean-Michel Morel, Ping Yu)

United States Patent Office has awarded Cognitech US Patent #820059 L. Rudin et. Al.

“Video demultiplexing based on meaningful modes extraction” for an algorithm that is the basis of the Cognitech VideoActive Demultiplexing module, the most robust proprietary Demultiplexing software on the market.

Fast forward to 2019. Cognitech scientists have been extending the earlier methods for Automatic Demultiplexing to such important tasks as Video Search, and Sort and Indexing.

If the camera is PTZ, it is necessary to be able to group frames that do not even have the same content, but ‘linked’ spatially:

Once one or several of the video are Demultiplexed, the end-user can view these sorted camera feeds through Cognitech Video Investigator’s VSI Interface. VSI is a Video Scene Integrator, a specialized Video Forensics Software that is organizing CCTV to facilitate the investigation process of videos from multiple cameras, usually adjacent in space and time, like tracking the suspects that enters the department store and walks across areas covered by different cameras.

Manual tools are eventually to be supplemented by automatic Tracking and Video Search Tools. US Patent Office has awarded Cognitech a very versatile US Patent to Cognitech: L. Rudin et. Al.” System and method for image and video search, indexing and object classification” US Patent number: 8831357

These are also naturally Real-Time applications. For example, one may need to detect in the hours-long video each individual using an automated teller machine, assign this person an index, and store all indexed individuals into a database for subsequent retrieving based on attributes such as human height ( with automatic crime scene measurement tools). Similarly, the passing by vehicles can be detected, indexed, and stored. Moreover, identifying attributes can also be extracted, such as vehicle color, dimensions and eventually Make and Model, a good application of video forensics analysis software.
