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.

执行信息

• 多线程作用域：全局（可从任何线程调用）。
• 在元组级别上自动并行化。
• 在通道级别上自动并行化。
• 在内部数据级别上自动并行化。

参数

结果

gray_bothatgray_bothatGrayBothatGrayBothatGrayBothatgray_bothat returns 2 ( H_MSG_TRUE) if the structuring element is not the empty region.否则，将抛出异常。
