JPEG2000-Compatible Scalable Scheme for Wavelet-Based Video Coding

Blog Article

We present a simple yet efficient scalable Button Covers scheme for wavelet-based video coders, able to provide on-demand spatial, temporal, and SNR scalability, and fully compatible with the still-image coding standard JPEG2000.Whereas hybrid video coders must undergo significant changes in order to support scalability, our coder only requires a specific wavelet filter for temporal analysis, as well as an adapted bit allocation procedure based on models of rate-distortion curves.Our study shows that RASPBERRY LEMON scalably encoded sequences have the same or almost the same quality than nonscalably encoded ones, without a significant increase in complexity.A full compatibility with Motion JPEG2000, which tends to be a serious candidate for the compression of high-definition video sequences, is ensured.
