SYSTEM AND METHOD FOR RECOGNITION OF IMAGE INFORMATION

An image information recognition system is provided which quantifies an angle of rotation and/or magnification of a wiring pattern in an image to facilitate a subsequent image retrieval. The system comprises edge detecting means which detects an edge component from input digital image data, a first binarization processor means for applying a threshold operation to the image obtained to provide binarization image data comprising active and inactive picture elements, Hough transformation means for applying a Hough transformation to the binarization image, second binarization processor means for applying a threshold operation to the Hough transformed image to provide binarization image data comprising active and inactive picture elements, labeling processor means for collecting adjacent images in the binarization image into a group and labeling the group, representative point calculation means for determining the coordinates a of representative point for each group labeled, and linear component estimation means for determining a linear equation for a rectilinear portion of the edge component in the original image from coordinate information of respective representative points determined.
