Abstract:
A method of processing a block of image data, comprising:receiving first pass segmentation tags for a plurality of pixels within the block of image data; determining an image type for the block of Image data based on a set of predefined rules using statistics compiled from the first pass segmentation tags; and generating rendering tags for pixels within the block of image data as function of second pass segmentation tags and the image type, wherein the set of predefined rules comprises identifying the block as being of a first Image type if the ratio of the percentage of pixels of a first image class and the percentage of pixels of a second image class is greater than a first threshold; and identifying the block as being of a second image type if the ratio of the percentage of pixels of the second image class and the percentage of pixels of the first image class is greater than a second threshold.
