Applying Huffman Coding to Images and Data for Compression

Huffman coding is a method of data compression that is independent of the data type that is the data could represent an images and data. This compression scheme is used in JPEG. Huffman coding works by looking at the data stream that makes up the file to be compresses. The image compression is a technology in the field of digital image processing. Images are very important documents nowadays; to work with them in some applications they need to be compressed, more or less depending on the purpose of the application and it reduces the size of the files. The need for an efficient technique for compression of Images ever increasing because the raw images need large amounts of disk space store seems to be a big disadvantage during transmission & storage.so that compression techniques are used. There are various algorithms that performs this compression in different ways; some are lossless and keep the same information as the original image, some others loss information when compressing the image. In this paper we have to propose the Lossless technique method of image compression and decompression using a simple coding technique called Huffman coding. This lossless technique is simple in implementation and utilizes less memory.
