该代码主要应用于图像处理中的图像分割，其目的是简化或改变图像的表示形式，使得图像更容易理解和分析。图像分割通常用于定位图像中的物体和边界（线，曲线等）。更精确的，图像分割是对图像中的每个像素加标签的一个过程，这一过程使得具有相同标签的像素具有某种共同视觉特性。-The code is mainly used in image processing in image segmentation, which aims to simplify or change the representation of the image, making it easier to understand and analyze images. Image segmentation is typically used to locate objects in the image and the boundary (line, curve, etc.). More precisely, the image in the image segmentation is a process for each pixel tagged, this process so that the pixel with the same label having a common visual characteristic.
