atan2_imageatan2_imageAtan2ImageAtan2Imageatan2_image (算子名称)

名称

atan2_imageatan2_imageAtan2ImageAtan2Imageatan2_image — Calculate the arctangent of two images.

参数签名

atan2_image(ImageY, ImageX : ArctanImage : : )

描述

atan2_imageatan2_imageAtan2ImageAtan2ImageAtan2Imageatan2_image calculates the arctangent ImageYImageYImageYImageYimageYimage_y/ImageXImageXImageXImageXimageXimage_x of the input images ImageYImageYImageYImageYimageYimage_y and ImageXImageXImageXImageXimageXimage_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 ArctanImageArctanImageArctanImageArctanImagearctanImagearctan_image. The angles in ArctanImageArctanImageArctanImageArctanImagearctanImagearctan_image are represented in radians.

注意

atan2_imageatan2_imageAtan2ImageAtan2ImageAtan2Imageatan2_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.
