acos_image — Calculate the arccosine of an image.
acos_image calculates the arccosine of an input image Image and stores the result in the image ArccosImage. The angles in ArccosImage are represented in radians. If Image contains gray values outside the valid domain [-1,1] of the arccosine function, the corresponding gray values in ArccosImage are set to 0.
acos_image can be executed on OpenCL devices.
