In most classical lossless image compression schemes, images are scanned line by line, and so, only horizontal patterns are effectively compressed. The proposed approach attempts to better explore image correlation in different directions by adopting a context-based adaptive scanning process. The adopted scanning process aims to generate a compact one-dimensional image representation by using an image...
Most conventional lossless image compression schemes such as GIF and PNG use entropic coding to reduce redundancies that results in adjacent pixels correlation. In such schemes, images are scanned line by line, and so, only horizontal patterns are effectively compressed. The proposed approach attempts to more explore image correlation in different direction by adopting a context based scanning process...
