Enhanced Scalable Video Coding Technique with an Adaptive Dual Tree Complex Wavelet Transform

The scalable Video is the most suitable video format for the current day scenario where there are different varieties of electronic gadgets used to communicate and play back. As the device resolution varies, the codec designed for Scalable video (H.264/AVC) is the only solution for its support. But the challenge is in its transmission due to the limited network resources in wireless networks viz; bandwidth. This introduces jitter during video playback. This needs an effective Compression technique to reduce the possible transmission time. The paper presents a novel Adaptive Dual Tree Complex wavelet Transoform (ADT-CWT) using the efficient Motion Block Estimation (MBE), Diamond search with Large Diamond Search Path (LDSP) and a Small Diamond Search Path (SDSP). This technique effectively improves the performance of Scalable Video in wireless transmission. The PSNR and the Compression Ratio (CR) are considered for the comparison.
