An Improved Hierarchical Lossless Text Compression Algorithm
Several improvements to the Bugajski-Russo N-gram algorithm are proposed. When applied to English text these result in an algorithm with comparable complexity and approximately 10 to 30% less rate than the commonly used COMPRESS algorithm. I. The N-Gram Algorithm The N-gram algorithm of Bugajski and Russo [1] is a hierarchical dictionary-type universal lossless source coder for a finite source ...
متن کاملImage Lossless Compression Using Improved Espiht Technique
Lossless compression is a new technique for reduction of data quantity without reducing the quality of an image. The storage and transfer of compressed data is faster as compared to uncompressed data. To achieve high compression ratio and compression time, we use modified Embedded Zero Tree Wavelet (EZW), improved Enhanced Set-Partitioning In Hierarchical trees (ESPIHT) techniques. These techni...
متن کاملLow Ramification near Lossless Image Compression Technique
-The minimizations of the storage space and transmission time are the two most important riding factors in image compression for telemedicine. Keeping this in view this paper intend to focus on a comparative investigation of three near lossless image compression technique, NLIC (near lossless image compression), SPIHT with DWT (Discrete Wavelets Transform), RLE (Run Length Encoding) with DCT (D...
متن کاملRegion-based near-lossless image compression
We present a near-lossless technique for the compression of images, which is based on the partitioning of the image into regions of constant intensity. The boundary information associated with the image partition is encoded with the method of the transition points. The compression of the intensities of the regions is based on the usual entropy encoding of the context-modeled prediction residual...
متن کاملLossless and near-lossless image compression with successive refinement
We present a technique that provides progressive transmission and near-lossless compression in one single framework. The proposed technique produces a bitstream that results in progressive reconstruction of the image just like what one can obtain with a reversible wavelet codec. In addition, the proposed scheme provides nearlossless reconstruction with respect to a given bound after each layer ...
