Lossless Medical Image Compression using 1D/2D Linear Polynomial Coding Techniques

The medical images compressed losslessly using the promising 1D polynomial coding technique that utilized Differential Pulse Code Modulation (DPCM) firstly, along the threshold value for deterministic part, and efficient mixed encoder for probabilistic part. The results improved by more than 2 in Compression ratio (CR) compared to the traditional 2D techniques using the same tested medical grayscale images.
