摘要：The conventional image retrieving method is not satisfactory in accuracy ofretrieval. There has been a demand for a general-purpose method capable of rapidlyretrieving characteristic parts. The object is achieved by acquiring image data

representing an image with pixels arranged in a dot matrix pattern, detecting the edgepixels of the image according to the image data, extracting the edge pixel as thecharacteristic point when a pattern formed by the detected edge pixels and theirneighboring pixels is similar to a prescribed object to be extracted, and defining as thecharacteristic region the prescribed region in the image which has the extractedcharacteristic points in large number.
