ABSTRACT:
A method and apparatus for cropping an image in digital form. The image to be cropped is represented as a first digital array which is operated on by an edge enhancement transformation to generate a second, binary digital array wherein edges of the image are emphasized. The second digital array is then partitioned into predetermined segments which are typically rows and columns of the array and the pixel values of each row and column are summed to generate brightness sums. The second digital array is then partitioned into a first, brighter, central group of rows and a second, less bright group consisting of upper and lower borders of rows; and a third, brighter, central group of column and left and right borders of columns in accordance with predetermined criteria relating to the brightness sums. The boundaries between the borders and the central groups are then applied to the first digital array and only those pixel values corresponding to pixel values common to the first and third groups are output to generate a cropped image.
