Problems solved by technology

[0004] In the prior art, most of the edge extraction operations are performed directly after the grayscale processing of the color image. Although the data after grayscale is 8bit data, its value is still relatively large, resulting in that the edge extraction still remains higher computational complexity

Abstract

The invention discloses a binary image edge extraction device. The device comprises an acquisition unit, a storage unit, a processing unit and an image output unit. The acquisition unit is used for acquiring a binary image of the to-be-identified image and acquiring the pixel point data of the pixel points point by point according to the row and column addresses of the pixel points in the binary image; the storage unit is used for storing the pixel point data in a three-dimensional neighborhood matrix form according to the row and column addresses and outputting the pixel point data to the processing unit; the processing unit is used for carrying out edge feature extraction operation on the received pixel point data in the three-dimensional neighborhood matrix form according to the row and column addresses, recording an edge feature extraction operation result as an edge feature value, and inputting the edge feature value into the image output unit; and the image output unit is used for generating and outputting an edge feature image of the to-be-identified image. According to the technical scheme, the complexity of the edge extraction operation is reduced, and the data storage space is saved.

Description

technical field [0001] The present application relates to the technical field of image processing devices, and in particular, relates to a binary image edge extraction device. Background technique [0002] With the rapid development of information technology, image processing technology has also developed rapidly, and has been widely used in all aspects of daily life. In digital image processing, the edge feature is an important feature of the image, and it is an important part of image processing, pattern recognition and computer vision. The extraction operation of image edge features is widely used in industrial inspection, image segmentation, motion detection, human Face recognition and target tracking and other fields, and the results of image edge extraction will also directly affect the effect of further image processing and pattern recognition. [0003] The edge of the image is generally where the color of the image changes drastically, and these changes are often ca...
