Abstract

The application discloses a binary image edge extraction device, which includes: an acquisition unit, a storage unit, a processing unit, and an image output unit; the acquisition unit is used to acquire the binary image of the image to be recognized, and The row and column addresses of the points are used to obtain the pixel point data of the pixel points point by point; the storage unit is used to store the pixel point data in the form of a three-dimensional neighborhood matrix according to the row and column addresses, and output to the processing unit; the processing unit is used to process according to the row and column addresses. The received pixel point data in the form of a three-dimensional neighborhood matrix is ​​subjected to an edge feature extraction operation, and the result of the edge feature extraction operation is recorded as an edge feature value, and the edge feature value is input to the image output unit; the image output unit is used to generate And output the edge feature image of the image to be recognized. Through the technical solution in this application, 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...
