acos_imageacos_imageAcosImageAcosImageacos_image (Operator)

acos_imageacos_imageAcosImageAcosImageacos_image — Calculate the arccosine of an image.

Signature

acos_image(Image : ArccosImage : : )

Herror acos_image(const Hobject Image, Hobject* ArccosImage)

Herror T_acos_image(const Hobject Image, Hobject* ArccosImage)

void AcosImage(const HObject& Image, HObject* ArccosImage)

HImage HImage::AcosImage() const

static void HOperatorSet.AcosImage(HObject image, out HObject arccosImage)

HImage HImage.AcosImage()

def acos_image(image: HObject) -> HObject

Description

acos_imageacos_imageAcosImageAcosImageacos_image calculates the arccosine of an input image ImageImageImageimageimage and stores the result in the image ArccosImageArccosImageArccosImagearccosImagearccos_image. The angles in ArccosImageArccosImageArccosImagearccosImagearccos_image are represented in radians. If ImageImageImageimageimage contains gray values outside the valid domain [-1,1] of the arccosine function, the corresponding gray values in ArccosImageArccosImageArccosImagearccosImagearccos_image are set to 0.

Attention

acos_imageacos_imageAcosImageAcosImageacos_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
