CUDALINK SYMBOL
CUDAImageSubtract
subtracts an amount x from each channel value in img.
subtracts an amount x from each channel value in mem.
gives an image in which each pixel is the difference of the corresponding pixels in 
and 
.
gives a CUDAMemory in which each pixel is the difference of the corresponding pixels in 
and 
.
Details
- The CUDALink application must be loaded using Needs["CUDALink`"].
works with binary, grayscale, and other images.
works with CUDAMemory and lists.
is equivalent to ImageSubtract[image1, val].- The image returned by
has the same dimensions as image. - If
is a single-channel image, each channel of 
is subtracted by 
in 
. - In
, the number x is normally in the range 0 to 1. 
gives an image with the same underlying data type as image, clipping or truncating values if necessary.
