Abstract
Device and method for image data compression using segmentation and classification, the method comprising the steps of: identifying regions in a received image comprised of image pixels; segmenting the image pixels into segmented regions, each segmented region corresponding to an identified region, and into an image background comprised of image pixels, if existing, not belonging to any of the identified regions; determining a class for each segmented image region from a plurality of predetermined image classification classes; applying an image learning-based encoder to each segmented image region, according to the determined class of each segmented image region, wherein a specific image learning- based encoder has been preselected for each of the image classification classes from a library of image learning-based encoders; outputting the encoded segmented image regions.
