atan2_imageatan2_imageAtan2ImageAtan2Image (Operator)

Name

atan2_imageatan2_imageAtan2ImageAtan2Image — Calculate the arctangent of two images.

Signature

atan2_image(ImageY, ImageX : ArctanImage : : )

Description

atan2_imageatan2_imageAtan2ImageAtan2ImageAtan2Image calculates the arctangent ImageYImageYImageYImageYimageY/ImageXImageXImageXImageXimageX of the input images ImageYImageYImageYImageYimageY and ImageXImageXImageXImageXimageX, 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 ArctanImageArctanImageArctanImageArctanImagearctanImage. The angles in ArctanImageArctanImageArctanImageArctanImagearctanImage are represented in radians.

atan2_imageatan2_imageAtan2ImageAtan2ImageAtan2Image 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.
