发明名称 Method of locating areas in an image such as a photo mask layout that are sensitive to residual processing effects
摘要 Images such as mask layouts, signatures, and photographs are compared to identify similarities or dissimilarities in the images. Descriptions of the images use geometric shapes including lines, rectangles, and triangles to facilitate the comparisons and decrease comparison time and decrease stored data describing the shapes. Data for pixels in the shapes are pre-integrated to reduce arithmetic operations in the comparisons.
