  • DIFFERENTIATED PROCESSING METHOD OF IMAGE ZONES
    Publication number: 20130022269
    Abstract: A method for improving the perception of an image may include performing a main separation of the pixels of the image into two categories, one corresponding to pixels of a flat zone, and the other corresponding to pixels of a textured zone. The method may also include processing the pixels of each category according to a method optimized according to the type of zone. Before the main separation step, a preliminary separation of the pixels may be performed into one category of normal pixels intended for the main separation step, and one category of singular pixels, with the criterion for selecting the singular pixels being adapted to identify pixels that would be wrongly identified as pixels of a textured zone. The singular pixels may then be processed according to a method adapted to their nature.
