Description

technical field

[0001] The invention relates to image processing, especially a method for implementing edge detection in image processing and a method for implementing deformable contour extraction in the field of image segmentation. Background technique

[0002] In various image applications, as long as it involves the extraction and measurement of image objects, image segmentation is inseparable. Image segmentation refers to extracting the target region or region of interest in the image by using some features in the image information. Usually, the target region or region of interest is called the foreground region, and the rest is called the background region.

[0003] Image segmentation is a key step from image processing to image analysis. As far as specific image segmentation algorithms are concerned, there are thousands of related research literatures. These studies mainly adopt the following two modes: the first one is "bottom-up" processing, including several sta...
