SYSTEM AND METHOD FOR IMAGE EDGE DETECTION AND REFLECTION USING DISCRETE COSINE TRANSFORMS

摘要

The image processing system of the present invention provides electronic edge detection and image reflection in keeping with ISO/JPEG/MPEG international compression standards for electronic imaging. Specifically, a novel electronic image processing system for edge detection and image reflection includes: an image acquisition device for acquiring and representing an image as an electronic image signal; a video memory for storing the image signal; a display for displaying the image signal; a raster to block converter for converting the image signal into block format; a DCT/IDCT processor for transforming the converted signal in acordance with predetermined basis matrices stored in a basis matrix memory; a mask multiplier for generating a mask multiplied signal in accordance with predetermined Laplacian matrices stored in an A matrix memory; a buffer for storing the mask multiplied signal; and a controller for controlling the image processing system in accordance with instructions from a central processing unit (CPU).
