Combined Spatial and Subband Block Coding of Images
This paper describes a low-memory cache efficient Hybrid Block Coder (HBC) for images in which an image subband decomposition is partitioned into a combination of spatial blocks and subband blocks, which are independently coded. Spatial blocks contain hierarchical trees spanning subband levels, and are each encoded using the SPIHT algorithm. Subband blocks contain a block of coefficients from w...
متن کاملA Review of Subband Coding of Seismic
In this paper, the literature published on lossy compression of seismic data using the popular subband coding technique is reviewed. The strong links between subband coding, transform coding, and the more recent discrete wavelet transform coding are described. The performance of seismic data subband coding depends on the proper choice of lter bank and frequency partitioning in the subband domai...
متن کاملTemporally scalable motion compensated adaptive temporal subband coding of video
It has been asserted that temporal subband coding (TSB) is inferior to predictive coding for regionally motion compensated (e.g. block-based MC) temporally scalable compressed video [1]. There are two major disadvantages of TSB coding: temporal ltering distortions, and `open-loop' predictive coding of covered and uncovered regions. The `open-loop' structure of TSB coding, however, a ords two ma...
متن کاملProjection−Based Time−Varying Subband Image Coding (MP−L1)
A novel class of time−varying subband transforms and its application in image coding are introduced. The proposed coding method is an extension of conventional one with multiple block−based transforms. At each time instance (block), the transform to be applied is chosen from a given set of orthogonal subband transforms according to a certain criterion. The reconstruction from the transformed co...
متن کاملSubband Coding Methods for Seismic Data Compression∗
This paper presents a study of seismic data compression techniques and a compression algorithm based on subband coding. The algorithm includes three stages: a decorrelation stage, a quantization stage that introduces a controlled amount of distortion to allow for high compression ratios, and a lossless entropy coding stage based on a simple but efficient arithmetic coding method. Subband coding...
