Description🔗

atan2_imageAtan2Image calculates the arctangent \(\textrm{ImageY}/\textrm{ImageX}\) of the input images ImageYimageYimage_y and ImageXimageXimage_x, using the signs of the gray values of the two images to determine the quadrant of the result, and stores the result in the image ArctanImagearctanImagearctan_image. The angles in ArctanImagearctanImagearctan_image are represented in radians.

Attention🔗

atan2_imageAtan2Image can be executed on an OpenCL device for int1, int2, int4, and real images. Note that the results of the OpenCL code may vary from the results produced by the CPU.
