Abstract
Embodiments of the present disclosure include methods, apparatuses, and systems for identifying regions to be filtered during processing of an image. A map generator is configured to receive pixels of an image and to determine a map for the image. The map indicates a number of islands within blocks of pixels of the image, where individual ones of the islands include either a single dark pixel, or two or more contiguous dark pixels, bordered by light pixels and/or one or more edges of the blocks of pixels. An index generator sets, based at least on the number of islands within the individual ones of the blocks of pixels that correspond to regions of the scanned image, filter indices for the regions of the scanned image. An image filter component, based on the filter indices, filters the regions of the scanned image.
