Implementation of Intermediate Image Processing for Video from Closed Circuit Television Cameras

摘要

Surveillance cameras and CCTV cameras are crucial in the present day society. The installation of such cameras provides public safety and protection against theft and vandalism. Most surveillance camera doesn’t have the capability to provide a clear footage. Therefore it has become a necessity to improve the quality of the video. The video processing provided in this paper would allow the user to get an enhanced quality video from a low quality video; this could be useful in identifying the perpetrator for the aforeknown activities. Image processing is very important in ameliorating a raw image captured by a CMOS or CCD sensor. In this paper we have taken surveillance footage and extracted the frames from the video, each of these frames undergo automatic colour balance, interpolation on the filter which resides over the sensor, gamma correction. The enhanced images are then used to recreate the video. The video after processing gives an enhanced and a finer quality in the video. The proposed method is implemented in MATLAB.
