AbstractContext-based image compression, using the property of medical images that are highly related to neighboring gray-scale pixels can be used to predict the next pixel. Once the pixels from the previous rows and the previous columns are known to the encoder, the current pixel can be predicted and the prediction errors which are only small numbers will be transmitted so that the decoder at the remote site can rebuild the original images accurately. The compression is accomplished because the coding required small errors need less number of bits, than needed for the regular pixels. In this study, five test images were scanned, converted to BMP file format, using JPEG's eight modes of predictors for modeling, and compressed using LZW, Huffman, and arithmetic compression algorithms. 'The results are analyzed and discussed.
