Video Editing
ClearView Communications have many years of experience in providing video editing and processing systems to the police service for handling CCTV and digital video material. We have combined industry-leading digital video processing technology with proven applications developed specifically to help law enforcement professionals turn raw images into real evidence. We can recommend the optimal build from a comprehensive toolset that enables analysts to extract the best evidence possible from their video.
Clearview's advanced video and audio processing technology and media management tools are used by police, customs and military operatives around the world. Our tools are being used by forensic video analysts to refine and analyse surveillance video captured from a huge range of sources.
Our specialist forensic software gives forensic video analysts the power to capture, process, and output uncompressed multiplexed images, highlight and track suspects, and clarify video to reveal hidden details recorded within field-based images. An unlimited number of still images can be pulled instantly from the video evidence for disclosure purposes.
ClearView's specialist video editing and processing systems offer capabilities including:
Averaging & Integration
Averaging is a method of using multiple frames to eliminate random noise or other random factors such as snowfall or rain from the video sequence. Static detail though a series of frames is greatly enhanced. Averaging and Integration can be applied to live or recorded video.
Brightness & Contrast
Improve the brightness and contrast of single image or entire video sequences. Can be applied before video is captured for improving the original information before further enhancement is applied.
Colour Correction
Automatic histogram equaliser enhances under developed video increasing the level of detail within a sequence. Automatic adjustment of colour balance restores an incorrect taint to the video which can be caused for example by coloured street lighting.
Zoom & Rotate
Correct rotated video which may be caused by recordings from damaged cameras. Rotate the position of detail with a sequence for enhancement, such as registration plates. Zoom in to CCTV video to maximise the viewing area.
Field Alignment
Moving objects are often captured by a camera at two slightly different locations resulting is a image which is unaligned. Reading detail from such recording is almost impossible. Field Alignment separated the image frame into 2 fields, odd and even and allows the user to move one or the other until the detail which is required is back in alignment and fully readable.
Filters
ClearView's systems provide users with a list of powerful filters which can be applied to demultiplexed CCTV video. The filters each have their own properties and can be used to blur, sharpen, reduce noise or find edges of details. Filters can greatly improve the enhancement of CCTV video or find detail which is difficult to see with the naked eye.
Joining & Scripting
Quickly create a sequence of events or a storyboard by joining sections of recorded cameras into a single video sequence. Users may also join saved sequences from the systems hard drive or RS unit into one complete sequence which may then be recorded to DVD disk for viewing.
Masking & Tracking
Masking & Tracking are methods of applying overlays to an image or video sequence for the purposes of highlighting or blocking image data. The system possesses 3 types of mask including a standard coloured shape for blocking detail, a blur for a subtle disfiguration of detail or a highlight to attract a views attention to a section of the screen. All 3 masks are displayed live on the VGA and analog monitor and can be recorded to tape or saved to DVD . Masks may also be used to follow or track targets across the screen though a video sequence.
Image comparison
Using 2 images, the system applies calculations to highlight subtle differences which may be missed with the naked eye. Using a selection of tools users can find differences between 2 seemingly identical images, making obvious any changes.
