APPARATUS AND METHOD FOR EXTRACTING EDGE IN IMAGE

摘要

PURPOSE: A device and method for an image outline are provided to perform feature point extraction with high reliability even in quantizing noise and complex images by applying a computer vision method and an image signal processing method. CONSTITUTION: A noise removing unit (11) removes noise generated from input images. An inclination calculator (12) calculates the inclination of the image without noise. An inclination intensity calculator (13) calculates the intensity of the inclination. An initial outline detector (14) detects initial outlines from the image without noise using the inclination and intensity in accordance with a first standard., A final outline extractor (15) extracts final outlines among the initial outlines on the basis of a second standard.
