Abstract :
Video compression is reducing and removing redundant video data so that a digital video file can be effectively sent and stored. The compression process is used to create a compressed file for transmission or storage by applying an algorithm. To play the compressed file, an inverse algorithm is applied to produce a video that shows virtually the same content as the original source video. In this paper, different wavelets like Haar, Daubechies, Biorthogonal, Symlet were used to perform video compression for the given video input. These wavelets were compared with different input video formats like MPEG, AVI, and WMV formats and the output was observed using the parameters Peak Signal to Noise ratio, Retained Energy and Compression Ratio in MATLAB.
