Abstract

Handling uncompressed video digital data need a huge storage. In this research,an uncompressed video frame needs 1 MB for data storing, otherwise the storage capacity is limited. To compress a video surveillance, a method which was used in this research is Video Surveillance Compression Base on Edge Detection with Wavelet Transform. Firstly, at encoder side, the dominant edges of a frame were detected and decoded as information side. The good categorized decoders are one step decomposition and 64 for quantization value. If decomposition process go to next second step, then quality of reconstructed frame became worse visually with PSNR value 25,11dB. To obtain searched frame that should be compressed, the error values were used as video frames spatial different. The allowable of error values for succeeded compression are from 0,02 to 0,04 , meanwhile those bigger then 0,04 produced a few compressed frame with just a 1% compression factor. The compression factor which so low that it causes data lost of much information.To get encoding performance comparison based on edge detection and Discreate Wavelet Transform (DWT) standard, measurement of Peak Signal to Noise Ratio (PSNR) was employed. From the results obtained the applied methods was siutable to video surveillance compression.
