A Wavelet Filter Evaluation for an Inter-Frame JPEG 2000 Adaptive Video Coding System

In this paper, we present an evaluation of various wavelet filters in the context of a JPEG 2000 based inter frame video coding system both on software and on hardware side. The software system itself is based on coding of a combination of intra frames and/or differential frames. Motion indicators are introduced and performed on the differential frames to determine the motion content (high or low) of the frame on a block basis. These motion indicators are utilized to decide whether to code differential frames or intra frames, to form an adaptive Group of Picture structure. The usage of different wavelet filters (Daubechies-9/7, Daubechies-5/3, Haar, etc.) for intra/differential frames is investigated, where we mainly focus on coding time and average video quality of the video stream. We port this software system to a hardware system. Experiments exhibit the difference (both in implementation and performance) of using wavelet filters on software and on hardware system.
