atan2_imageatan2_imageAtan2ImageAtan2Imageatan2_image (Operator)
Name
atan2_imageatan2_imageAtan2ImageAtan2Imageatan2_image
— Calculate the arctangent of two images.
Signature
Description
atan2_imageatan2_imageAtan2ImageAtan2Imageatan2_image
calculates the arctangent
ImageYImageYImageYimageYimage_y
/ImageXImageXImageXimageXimage_x
of the input images
ImageYImageYImageYimageYimage_y
and ImageXImageXImageXimageXimage_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 ArctanImageArctanImageArctanImagearctanImagearctan_image
. The angles
in ArctanImageArctanImageArctanImagearctanImagearctan_image
are represented in radians.
Attention
atan2_imageatan2_imageAtan2ImageAtan2Imageatan2_image
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.
Execution Information
- Supports OpenCL compute devices.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.
- Automatically parallelized on channel level.
- Automatically parallelized on domain level.
