描述

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

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 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_dilationgray_dilationGrayDilationGrayDilationGrayDilationgray_dilation returns 2 ( H_MSG_TRUE) if the structuring element is not the empty region.否则，将抛出异常。
