名称

gray_erosiongray_erosionGrayErosionGrayErosiongray_erosion — Perform a gray value erosion on an image.

参数签名

gray_erosion(Image, SE : ImageErosion : : )

描述

gray_erosiongray_erosionGrayErosionGrayErosionGrayErosiongray_erosion applies a gray value erosion to the input image ImageImageImageImageimageimage with the structuring element SESESESESEse. The image type of the structuring element SESESESESEse must match the image type of the input image ImageImageImageImageimageimage. The gray value erosion of an image i with a structuring element s at the pixel position x is defined as: Here, S is the domain of the structuring element s (see read_gray_seread_gray_seReadGraySeReadGraySeReadGraySeread_gray_se).

The gray value erosion is particularly fast for flat structuring elements, i.e., structuring elements with a constant gray level within their domain.
