CUDALink
CUDALINK SYMBOL

CUDAOpening


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


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


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

DetailsDetails

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

Basic Examples (5)Basic Examples (5)

First, load the CUDALink application:

In[1]:=
Click for copyable input

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

In[2]:=
Click for copyable input
Out[2]=

The radius can be varied:

In[1]:=
Click for copyable input
Out[1]=

works with lists:

In[1]:=
Click for copyable input
Out[1]//MatrixForm=

works with graphics objects:

In[1]:=
Click for copyable input
Out[1]=

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

In[1]:=
Click for copyable input

This performs the opening operation:

In[2]:=
Click for copyable input
Out[2]=

This gets the memory back to the CPU:

In[3]:=
Click for copyable input
Out[3]=

Memory must be deleted:

In[4]:=
Click for copyable input
Out[4]=
