CUDAErosion

CUDAErosion[img,r]

gives the morphological erosion of img with respect to a range-r square.

CUDAErosion[list,r]

gives the morphological erosion of list with respect to a range-r square.

CUDAErosion[mem,r]

gives the morphological erosion of mem with respect to a range-r square.

Details

  • The CUDALink application must be loaded using Needs["CUDALink`"].
  • CUDAErosion works with binary, grayscale, and other images.
  • CUDAErosion works with CUDAMemory and lists.
  • CUDAErosion[image,r] is equivalent to Erosion[image,r].
  • If multiple image channels are present, CUDADilation operates on each of them separately.
  • The following options can be given:
  • "Device"Automaticdevice used for CUDA computation
    Padding"Fixed"value used on boundary
    "OutputMemory"NoneCUDAMemory where output is stored

Examples

Basic Examples  (6)

First, load the CUDALink application:

Erosion reduces smaller, light features:

Erosion of a grayscale image:

Erosion operates on each color channel independently:

Erosion can be used to perform a max filter on an input list:

CUDAErosion works with graphics objects:

Using CUDAMemory, one can speed up computation by reducing the amount of memory operations. This loads memory onto the CPU:

This performs the erosion operation:

This gets the memory back to the CPU:

Memory must be deleted:
