New Methods for Lossless Image Compression Using Arithmetic Coding

Lossless image compression presents a unique set of challenges. Considerable research has already been done on lossless text compression [1,2,3,4,5]; all good methods found to date involve some form of moderately high-order exact string matching. However, this work cannot easily be carried over to lossless image compression, for two reasons: First, images are two-dimensional, so the contexts ar...

Lossless Image Compression and Decompression Using Huffman Coding

This paper propose a novel Image compression based on the Huffman encoding and decoding technique. Image files contain some redundant and inappropriate information. Image compression addresses the problem of reducing the amount of data required to represent an image. Huffman encoding and decoding is very easy to implement and it reduce the complexity of memory. Major goal of this paper is to pr...

Lossless Image Compression Using Data Folding Followed By Arithmetic Coding

The paper presents a lossless image compression technique using the hybridization of two different entropy coding techniques. Initially data folding technique has been applied to the image. A row folding is applied on the image matrix followed by a column folding. Multiple iterations of this process is applied on the image. After completing the data folding process another entropy coding techni...

Lossless-by-Lossy Coding for Scalable Lossless Image Compression

This paper presents a method of scalable lossless image compression by means of lossy coding. A progressive decoding capability and a full decoding for the lossless rendition are equipped with the losslessly encoded bit stream. Embedded coding is applied to largeamplitude coefficients in a wavelet transform domain. The other wavelet coefficients are encoded by a context-based entropy coding. Th...

Lossless Image Compression using a

This paper describes a new straightforward technique for lossless image compression, entitled SPM (Simple Prediction Method), which results in compression ratios similar to those achieved by the most powerful techniques described in the literature. The predictive model used by the method is one in which the current point is predicted as a weighted average of the preceding neighbouring points. T...
