ABSTRACT:
According to the method of and apparatus for image processing, feature information of each picture element is extracted from image data received. An attribute of each picture element is determined on the basis of the aforesaid feature information. These attributes are corrected by detecting straight lines by applying a Hough transform to picture elements disposed along apparent border lines by which one attribute is divided from another, dividing the image data into a plurality of local regions by these straight lines, and determining an attribute with respect to each of the local regions. Each of the local regions is subjected to image processing in accordance with the corrected attribute.
