def atan2_image(image_y: HObject, image_x: HObject) -> HObject

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.
