A NOVEL APPROACH OF LOSSLESS IMAGE COMPRESSION USING TWO TECHNIQUES

With the advent in technology, there exist many compression schemes, each being unique in itself. However, the decision to use one in a particular situation is dictated largely by the type of data being compressed. The greater the compression ratios the more dependent the method tends to be. Several lossless techniques have been proposed so far for Image Compression. Here we study a lossless image compression using two techniques i.e. Delta encoding and Run length. Delta encoding is a simple compression scheme for audio, EEG, and general time series data files. Numerous past researches projects have observed that one can compress one object relative to another one by computing the differences between the two, delta-encoding systems have almost invariably required knowledge of a specific relationship between them most commonly. The idea of delta encoding to reduce communication or storage costs is not new. Using lossless run length encoding technique together we propose a new algorithm for lossless image compression.
