The Criminal Investigation Design Of Digital Image Processing System

With the construction of the "Safe City", the digital imaging video surveillance system has been widely used in public places such as banks, shopping malls, railway stations and traffic junctions, in order to achieve a comprehensive monitoring of public safety. Digital surveillance video investigation has become an important technical means of Investigative Work. A wide range of video surveillance equipment, digital imaging, combined with other objective constraints, resulting in Playback after the incident, has the image data is incomplete, the picture is not clear the problem, there is no way to provide effective clues of the case investigating this case and evidence, and the image will appear to the facial features of the suspect is not clear illegible, the suspect vehicle license plate illegible, have brought a great deal of trouble to solve the case and the case of the criminal investigation department of forensics. In the process of criminal investigation the investigation of cases in a digital image processing system is very necessary.The Criminal Investigation digital image processing system design fully into account the various factors affecting the image quality of the video image acquisition, analysis, processing organic combination of the characteristics of a criminal investigation digital image analysis to form a sequence of images and single image integration in the process of criminal video imaginganalytical processing environment. On the one hand, the system by the target of interest in the video or image geometry correction, color correction, restoration, image enhancement, noise, ambiguity removal, image restoration, the complex environment processing, fusion enhancement and super-resolution techniques to eliminate or reduction of various factors degraded. On the other hand, the system uses the model learning, multi-frame and multi-modal handling mechanism to effectively enhance the video image information for investigators and technical workers provide a strong technology platform, a comprehensive analysis of the images video.
