摘要：Easy and less-time-consuming transmission of high quality digital images requires the compression-decompression technique to be as simple as possible and to be completely lossless. Keeping this demand into mind, we proposed the lossless image compression technique i.e Text Based Image Compression using Hexadecimal Conversion (TBICH). The key idea is to increase redundancy of data presented in an image to get the better compression. We are concerned with lossless image compression in this paper .Our proposed technique is Text Based Image compression using Hexadecimal conversion (TBICH). Our approach works as follows: firstly an image is encoded and converts it into text file by using hexadecimal numbers and LZ77 text compression is applied on this encoded file to reduce size. While decompressing, decompress the encoded file and convert into image which is same as original image. The main objective of this proposed technique is to reduce the size of the image without loss and also to provide security.
