gives the morphological dilation of img with respect to a range-r square.
gives the morphological dilation of list with respect to a range-r square.
gives the morphological dilation of mem with respect to a range-r square.

- The CUDALink application must be loaded using Needs["CUDALink`"].
works with binary, grayscale, and other images.
works with CUDAMemory and lists.
is equivalent to Dilation[image, r].- If multiple image channels are present,
operates on each of them separately. - The following options can be given:
-
"Device" Automatic device used for CUDA computation Padding "Fixed" value used on boundary "OutputMemory" None CUDAMemory where output is stored

First, load the CUDALink application:
| In[1]:= |
This removes smaller, dark features:
| In[2]:= |
| Out[2]= |  |
| In[1]:= |
| Out[1]= |  |
| In[1]:= |
| Out[1]= |  |
Dilation can be used to perform a min filter on an input list:
| In[1]:= |
Out[1]//MatrixForm= | |
 | |
| In[1]:= |
| Out[1]= |  |
Using CUDAMemory, one can speed up computation by reducing the amount of memory operations. This loads memory onto the CPU:
| In[1]:= |
This performs the dilation operation:
| In[2]:= |
| Out[2]= |  |
This gets the memory back to the CPU:
| In[3]:= |
| Out[3]= |  |
| In[4]:= |
| Out[4]= |  |
