This chapter examines a number of schemes used for lossless compression of images. It highlights schemes for compression of grayscale and color images as well as schemes for compression of binary images. Among these schemes are several that are a part of international standards. The joint photographic experts group (JPEG) is a joint ISO/ITU committee responsible for developing standards for continuous-tone still-picture coding. The more famous standard produced by this group is the lossy image compression standard. However, at the time of the creation of the famous JPEG standard, the committee also created a lossless standard. The old JPEG lossless still compression standard provides eight different predictive schemes from which the user can select. In addition, the context adaptive lossless image compression (CALIC) scheme, which came into being in response to a call for proposal for a new lossless image compression scheme in 1994, uses both context and prediction of the pixel values. The CALIC scheme actually functions in two modes, one for gray-scale images, and another for bi-level images. One of the approaches used by CALIC to reduce the size of its alphabet is to use a modification of a technique called recursive indexing. Recursive indexing is a technique for representing a large range of numbers using only a small set.read more

Improved CAVLC for H.264/AVC Lossless Intra-Coding
TL;DR: From experimental results, it is confirmed that the proposed CAVLC for lossless intra-coding by considering the statistical differences in residual data between lossy and lossless coding provides approximately 9% bit saving in terms of a compression ratio compared with the current H.264/AVC fidelity range extensions high profile.

Efficient Differential Pixel Value Coding in CABAC for H.264/AVC Lossless Video Compression
Heo Jin,Yo-Sung Ho +1 more
TL;DR: Considering the observed statistical properties of the differential pixel value in lossless coding, the CABAC encoding mechanism is modified with the newly designed binarization table and the context-modeling method and results show that the proposed method achieves an approximately 12% bit saving.

Naïve Bayesian Classifier for Rapid Assignment of rRNA Sequences into the New Bacterial Taxonomy
TL;DR: The RDP Classifier can rapidly and accurately classify bacterial 16S rRNA sequences into the new higher-order taxonomy proposed in Bergey's Taxonomic Outline of the Prokaryotes, and the majority of the classification errors appear to be due to anomalies in the current taxonomies.

The Laplacian Pyramid as a Compact Image Code
Peter J. Burt,Edward H. Adelson +1 more
TL;DR: A technique for image encoding in which local operators of many scales but identical shape serve as the basis functions, which tends to enhance salient image features and is well suited for many image analysis tasks as well as for image compression.
