CUDAOpening

CUDAOpening[img,r]

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

CUDAOpening[list,r]

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

CUDAOpening[mem,r]

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

Details and Options

  • The CUDALink application must be loaded using Needs["CUDALink`"].
  • CUDAOpening works with binary, grayscale, and other images.
  • CUDAOpening[image,r] is equivalent to Opening[image,r].
  • If multiple image channels are present, CUDAOpening 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  (5)

First, load the CUDALink application:

Use morphological opening to extract objects larger than the structuring element:

The radius can be varied:

CUDAOpening works with lists:

CUDAOpening works with graphics objects:

Using CUDAMemory, you can speed up computation by reducing the time spent on memory operations. This loads memory onto the GPU:

This performs the opening operation:

This gets the memory back to the CPU:

Memory must be deleted:
