Embodiment Construction

[0011] Fig. 1 is a system block diagram of color image edge detection according to the present invention.

[0012] As shown in FIG. 1 , the color image edge detection system according to the present invention includes a color space transformation module, a plurality of edge detection modules, and a classifier fusion module.

[0013] The color space transformation module is used to map the input image to a number of different color spaces.

[0014] Multiple edge detection modules are used to perform color image edge detection on images mapped to each color space and binarize all edge images, and then input each edge detection result to the classifier fusion module.

[0015] The classifier fusion module is used to integrate all the input edge detection results.

[0016] The following describes in detail the color image edge detection process in FIG. 1 according to a specific embodiment of the present invention.

[0017] First, simple preprocessing such as smoothing and denoisi...

Abstract

The present invention provides a color picture detecting method, characterized in that the input image is mapped to multiple different color spaces; the color images of the color space are processed edges detection respectively, obtaining the edge detecting result of each color space; the edge detecting results are syncretized. The invention processes edge detection in multiple color spaces, and uses class selector fusion technology integrated the detecting results, so as to combine the advantages of all kinds of color spaces expressed on the images, substantially utilizing the edge detecting results of all kinds of color space and improving the accuracy of the edge detection.

Description

technical field [0001] The invention relates to digital image processing, in particular to a color image edge detection method and equipment. Background technique [0002] An image edge is where there is a sudden change in pixel values ​​in the image, indicating where one region ends and another begins. Detecting the edge of the image can not only obtain most of the information of the image, but also determine the basic outline of the object in the image. Therefore, image edge detection is an important part of digital image processing, and an important means of image recognition, recovery, enhancement and reconstruction. [0003] There are many methods of image edge detection, such as differential edge detection. Most of the traditional edge detection methods are based on grayscale images. For color images: firstly, its color information is not fully utilized; secondly, edges are often not detected when the grayscale difference of the image is small, and sometimes It also...
