Grayscale Image Compression Based on Min Max Block Truncating Coding

Image compression is an important tool to reduce the bandwidth and storage requirements of practical image systems such as multimedia, communication, medical images, education and business etc. The image compression techniques are categorized into two main classification namely lossy compression techniques and lossless compression techniques. Lossy compression techniques lead to loss of data with higher compression whereas the lossless compression ratio gives good quality of compressed images, but yield only less compression. BTC is a lossy image compression technique, which reduce bit rate and preserving the low computational complexity.
