cos_imagecos_imageCosImageCosImagecos_image (Operator)

cos_imagecos_imageCosImageCosImagecos_image — Calculate the cosine of an image.

Signature

cos_image(Image : CosImage : : )

Herror cos_image(const Hobject Image, Hobject* CosImage)

Herror T_cos_image(const Hobject Image, Hobject* CosImage)

void CosImage(const HObject& Image, HObject* CosImage)

HImage HImage::CosImage() const

static void HOperatorSet.CosImage(HObject image, out HObject cosImage)

HImage HImage.CosImage()

def cos_image(image: HObject) -> HObject

Description

cos_imagecos_imageCosImageCosImagecos_image calculates the cosine of an input image ImageImageImageimageimage and stores the result in the image CosImageCosImageCosImagecosImagecos_image of type real. If ImageImageImageimageimage is of type direction or cyclic, the angles in ImageImageImageimageimage are converted to radians internally. If ImageImageImageimageimage is of type real, the angles in ImageImageImageimageimage are assumed to be represented in radians. For direction images, the value of 255 will result in a value of 0 in the output image.

Attention

cos_imagecos_imageCosImageCosImagecos_image can be executed on OpenCL devices.

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.

Parameters
