Abstract
Discrete multiresolution transforms based on two-channel linear-phase FIR filterbanks and their variants are used ubiquitously for coding natural images/videos. In real-time video applications such as the video conferencing or surveillance, constraining the end-to-end delay incurred by temporal multiresolution transforms is critical for timely response. In this paper, we attempt to minimize the delay of the analysis/synthesis banks for generic two-channel linear-phase FIR filterbanks by analytically formulating the temporal dependency between the reconstructed frames and the input frames. As a result, the closed-form of the minimal delay is attained and proved.
