CUDAImageDivide

CUDAImageDivide[img,x]

divides each channel value in img by an amount x.

CUDAImageDivide[mem,x]

divides each channel value in mem by an amount x.

CUDAImageDivide[img1,img2]

gives an image in which each pixel is the division of the corresponding pixels in img1 and img2.

CUDAImageDivide[mem1,mem2]

gives a CUDAMemory in which each pixel is the division of the corresponding pixels in mem1 and mem2.

Details and Options

  • The CUDALink application must be loaded using Needs["CUDALink`"].
  • CUDAImageDivide works with binary, grayscale, and other images.
  • CUDAImageDivide works with CUDAMemory and lists.
  • CUDAImageDivide[image1,x] is equivalent to CUDAImageMultiply[image1,1/x].
  • The image returned by CUDAImageDivide[image,…] has the same dimensions as image.
  • image1 and image2 must be the same dimensions in CUDAImageDivide[image1,image2].
  • If image2 is a single-channel image, each channel of image1 is divided by image2 in CUDAImageDivide[image1,image2].
  • In CUDAImageDivide[image,x], the number x is normally in the range 0 to 1 and is not defined at 0.
  • CUDAImageDivide[image,x] gives an image with the same underlying data type as image, clipping or truncating values if necessary.
  • CUDAImageDivide[image1,image2] gives an image with the type of image1, clipping or truncating values if necessary.
  • The following options can be given:
  • "Device"Automaticdevice used for CUDA computation
    "OutputMemory"NoneCUDAMemory where output is stored

Examples

Basic Examples  (3)

First, load the CUDALink application:

This divides each pixel of the input image by a constant value 0.5:

This divides each pixel of the input image by a constant value 2.0:

CUDAImageDivide can be used to multiply rank 2 or 3 lists:
