CUDAImageAdd

CUDAImageAdd[img,x]

adds an amount x to each channel value in img.

CUDAImageAdd[mem,x]

adds an amount x to each channel value in mem.

CUDAImageAdd[img1,img2]

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

CUDAImageAdd[mem1,mem2]

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

Details and Options

  • The CUDALink application must be loaded using Needs["CUDALink`"].
  • CUDAImageAdd works with binary, grayscale, and other images.
  • CUDAImageAdd works with CUDAMemory and lists.
  • CUDAImageAdd[image1,x] is equivalent to ImageAdd[image1,x].
  • The image returned by CUDAImageAdd[image,…] has the same dimensions as image.
  • image1 and image2 must be the same dimensions in CUDAImageAdd[image1,image2].
  • If image2 is a single-channel image, each channel of image1 is added to image2 in CUDAImageAdd[image1,image2].
  • In CUDAImageAdd[image,x], the number x is normally in the range 0 to 1.
  • CUDAImageAdd[image,x] gives an image with the same underlying data type as image, clipping or truncating values if necessary.
  • CUDAImageAdd[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
