Abstract
A system that scans an image into a computer system and then locates left and right edges of information within each row of the image. The system defines top and bottom rows of information as first and last rows of a number of consecutive rows of the image that have a number of pixels between the left and right edges. The system linearizes the edge data, places a left boundary at the leftmost point of the linearized left edge, and places a right boundary at the rightmost point of the linearized right edge. Each pixel within the boundaries is analyzed to classify the pixel as white, light gray, dark gray, black, colored, or as having some color; a percentage of pixels in each class is created; and the image classification is determined using these percentages. The system displays the image and image classification, with the boundary superimposed over the image.
