ABSTRACT:
An apparatus, and corresponding method for finding an area of interest in an input image, filters the input image with at least one compression filter to generate a final compressed image. The apparatus determines the location of an artifact in the final compressed image and then determines the location of the area of interest in the input image according to the location of the artifact in the final compressed image. An apparatus, and corresponding method for finding one or more artifacts in a two-dimensional image, receives a first row of the image and generates a list of regions in accordance with the first row. The apparatus receives a next row of the image and updates the list of regions in accordance with the next row. The apparatus determines whether a region in the list of regions corresponds to an artifact in the image and, if so, selects the region as the artifact.
