摘要：

This research aims to propose the method of the CCTV image enhancement using sub-images homomorphic filtering techniques. The experiments were conducted using CCTV video clips which recorded from both indoor and outdoor surveillance video system. The processes started by dividing video clip into image frames, then separate both horizontal and vertical parts before enhancing with homomorphic filtering methods. The results given quite good performance in terms of PSNR. Therefore the proposed method based on homomorphic filtering techniques using sub-images dividing can be used to improve the quality of CCTV images.
