An Innovative Lossless Compression Method for Discrete-Color Images

This is an article off my M.Sc. thesis published in 2015 in the rather serious venue IEEE Transactions on Image Processing (PDF here): In this paper, we present an innovative method for lossless compression of discrete-color images such as map images, graphics, GIS as well as binary images. This method comprises two main components. The … Continue reading An Innovative Lossless Compression Method for Discrete-Color Images
