CUDALINK SYMBOL
CUDAErosion
gives the morphological erosion of img with respect to a range-r square.
gives the morphological erosion of list with respect to a range-r square.
gives the morphological erosion of mem with respect to a range-r square.
Details
- The CUDALink application must be loaded using Needs["CUDALink`"].
works with binary, grayscale, and other images.
works with CUDAMemory and lists.
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" Automatic device used for CUDA computation Padding "Fixed" value used on boundary "OutputMemory" None CUDAMemory where output is stored

Basic Examples (6)
First, load the CUDALink application:
| In[1]:= |
Erosion reduces smaller, light features:
| In[2]:= |
| Out[2]= |  |
| In[1]:= |
| Out[1]= |  |
Erosion operates on each color channel independently:
| In[1]:= |
| Out[1]= |  |
Erosion can be used to perform a max 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 erosion operation:
| In[2]:= |
| Out[2]= |  |
This gets the memory back to the CPU:
| In[3]:= |
| Out[3]= |  |
| In[4]:= |
| Out[4]= |  |
