CUDAColorNegate

CUDAColorNegate[image]

performs color negation on image.

CUDAColorNegate[list]

performs color negation on list.

CUDAColorNegate[mem]

performs color negation on memory referenced by mem.

Details and Options

The CUDALink package must be loaded using Needs["CUDALink`"].
CUDAColorNegate works with binary, grayscale, and other images.
CUDAColorNegate works with CUDAMemory and lists.
If multiple image channels are present, CUDAColorNegate operates on each of them separately.
If the input type is Real, then the input is subtracted from 1.0, not 255.
CUDAColorNegate does not work on fixed vector structure types like "Float[2]", "Integer32[2]", ….
The following options can be given:
"Device" $CUDADevice CUDA device used to perform computation

"OutputMemory" None output memory provided to avoid creating new memory location

First, load the CUDALink application:

This performs color negation on the input color image:

This inverts a grayscale image:

This inverts a binary image:

This performs color negation on the input list:

If the input is CUDAMemory, then memory is returned as output:

This negates the input:

Memory is retrieved using CUDAMemoryGet:
