名称

gray_tophatgray_tophatGrayTophatGrayTophatgray_tophat — Perform a gray value top hat transformation on an image.

参数签名

描述

gray_tophatgray_tophatGrayTophatGrayTophatGrayTophatgray_tophat applies a gray value top hat transformation 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 top hat transformation of an image i with a structuring element s is defined as i.e., the difference of the image and its opening with s (see gray_openinggray_openingGrayOpeningGrayOpeningGrayOpeninggray_opening). For the generation of structuring elements, see read_gray_seread_gray_seReadGraySeReadGraySeReadGraySeread_gray_se.

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