acos_imageacos_imageAcosImageacos_imageAcosImageAcosImage (Operator)

Name

acos_imageacos_imageAcosImageacos_imageAcosImageAcosImage — Calculate the arccosine of an image.

Signature

acos_image(Image : ArccosImage : : )

Description

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

Attention

acos_imageacos_imageAcosImageacos_imageAcosImageAcosImage can be executed on OpenCL devices.
