名称

acos_imageacos_imageAcosImageAcosImageacos_image — 计算图像的反余弦。

参数签名

描述

acos_imageacos_imageAcosImageAcosImageAcosImageacos_image calculates the arccosine of an input image ImageImageImageImageimageimage and stores the result in the image ArccosImageArccosImageArccosImageArccosImagearccosImagearccos_image. The angles in ArccosImageArccosImageArccosImageArccosImagearccosImagearccos_image are represented in radians. If ImageImageImageImageimageimage contains gray values outside the valid domain [-1,1] of the arccosine function, the corresponding gray values in ArccosImageArccosImageArccosImageArccosImagearccosImagearccos_image are set to 0.

注意

acos_imageacos_imageAcosImageAcosImageAcosImageacos_image can be executed on OpenCL devices.
