Abstract
A method for transmission of images and/or video over bandwidth limited transmission channels having varying available bandwidth, which uses a classification algorithm to decompose the images and/or video to be transmitted into multiple spatial areas, each area having a specific image type; detecting the image type of each of those areas; and separately selecting for each of those areas an image and/or video encoding algorithm having a compression ratio. The classification algorithm is used to prioritize each of the areas, increase the compression ratio of the image and/or video encoding algorithm dedicated to spatial areas having lower priority in case of decreasing bandwidth.
