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

HImage HImage.AbsImage()


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

abs_imageabs_imageAbsImageabs_imageAbsImageAbsImage 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.

Example (HDevelop)

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


The operator abs_imageabs_imageAbsImageabs_imageAbsImageAbsImage returns the value 2 (H_MSG_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>)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)
