Three channel wavelet transform for video compression applications
Wavelet based compression of images and video remains an important topic. New constructions of three channel filter bank are presented. Three channel filter bank was integrated into open source video codec DIRAC. The results of three channel filter bank design and its implementation in the video compression system are given in comparison with two channel CDF 9/7 filter bank (used in JPEG2000) The experiments show that the usage of three channel wavelet transform in video compression gives higher PSNR values about 2 dB over traditional two channel wavelet transform or about 30% bitrate saving.
