名称

gray_dilationgray_dilationGrayDilationGrayDilationgray_dilation — Perform a gray value dilation on an image.

参数签名

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.

运行信息

• 多线程类型:可重入(与非独占操作符并行运行)。
• 多线程作用域:全局(可以从任何线程调用)。
• 在元组级别自动并行化。
• 在图像通道级别自动并行化。
• Automatically parallelized on internal data level.

参数表

结果

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