  • The CUDALink application must be loaded using Needs["CUDALink`"].
  • CUDAClosing works with binary, grayscale, and other images.
  • CUDAClosing works with CUDAMemory and lists.
  • CUDAClosing[image,r] is equivalent to Closing[image,r].
  • If multiple image channels are present, CUDAClosing 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

First, load the CUDALink application:

Wolfram Language code: Needs["CUDALink`"]

Morphological closing removes thin, dark features:

Wolfram Language code: CUDAClosing[[image], 2]

Use morphological closing to remove salt-and-pepper noise from a color photo:

Wolfram Language code: CUDAClosing[[image], 1]

Remove small holes in foreground objects:

Wolfram Language code: CUDAClosing[[image], 1]

CUDAClosing works with lists:

Wolfram Language code: MatrixForm[CUDAClosing[RandomInteger[{0, 255}, {5, 5, 3}], 1]]

CUDAClosing works with graphics objects:

Wolfram Language code: CUDAClosing[\!\(\*Graphics3DBox[«7»]\), 5]

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

Wolfram Language code: mem = CUDAMemoryLoad[[image]];

This performs the closing operation:

Wolfram Language code: CUDAClosing[mem, 1]

This gets the memory back to the CPU:

Wolfram Language code: CUDAMemoryGet[%]

Memory must be deleted:

Wolfram Language code: CUDAMemoryUnload[mem]

Applications  (1)

Clean an astronomical image:

Wolfram Language code: CUDAClosing[[image], 1]
