名称

gray_bothatgray_bothatGrayBothatGrayBothatgray_bothat — Perform a gray value bottom hat transformation on an image.

参数签名

gray_bothat(Image, SE : ImageBotHat : : )

描述

gray_bothatgray_bothatGrayBothatGrayBothatGrayBothatgray_bothat applies a gray value bottom 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 bottom hat transformation of an image i with a structuring element s is defined as i.e., the difference of the closing of the image with s and the image (see gray_closinggray_closingGrayClosingGrayClosingGrayClosinggray_closing). For the generation of structuring elements, 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.

结果

gray_bothatgray_bothatGrayBothatGrayBothatGrayBothatgray_bothat returns 2 ( H_MSG_TRUE) if the structuring element is not the empty region. Otherwise, an exception is raised.
