abs_imageabs_imageAbsImageAbsImageabs_image (Operator)

Name

abs_imageabs_imageAbsImageAbsImageabs_image — Calculate the absolute value (modulus) of an image.

Signature

abs_image(Image : ImageAbs : : )

Herror abs_image(const Hobject Image, Hobject* ImageAbs)

Herror T_abs_image(const Hobject Image, Hobject* ImageAbs)

void AbsImage(const HObject& Image, HObject* ImageAbs)

HImage HImage::AbsImage() const

static void HOperatorSet.AbsImage(HObject image, out HObject imageAbs)

HImage HImage.AbsImage()

def abs_image(image: HObject) -> HObject

Description

The operator abs_imageabs_imageAbsImageAbsImageAbsImageabs_image calculates the absolute gray values of images of any type and stores the result in ImageAbsImageAbsImageAbsImageAbsimageAbsimage_abs. The power spectrum of complex images is calculated as a real image. The operator abs_imageabs_imageAbsImageAbsImageAbsImageabs_image generates a logical copy of unsigned images.

abs_imageabs_imageAbsImageAbsImageAbsImageabs_image can be executed on an OpenCL device for int1, int2, int4, real, and complex images. However, since for OpenCL 1.0 only single precision floating point is supported for all devices, and not all rounding modes are supported, the OpenCL implementation can produce slightly different results from the scalar or SIMD implementations.

Result image(s).

Example (HDevelop)

convert_image_type (Image, ImageInt2, 'int2')
texture_laws (ImageInt2, ImageTexture, 'el', 2, 5)
abs_image (ImageTexture, ImageTexture)

Result

The operator abs_imageabs_imageAbsImageAbsImageAbsImageabs_image returns the value TRUE. The behavior in case of empty input (no input images available) is set via the operator set_system(::'no_object_result',<Result>:)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)set_system("no_object_result",<Result>)
