  • 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"Automaticdevice used for CUDA computation
    Padding"Fixed"value used on boundary
    "OutputMemory"NoneCUDAMemory where output is stored

First, load the CUDALink application:

In[1]:=
Click for copyable input

Erosion reduces smaller, light features:

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

Erosion of a grayscale image:

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

Erosion operates on each color channel independently:

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

Erosion can be used to perform a max filter on an input list:

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

works with graphics objects:

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

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

In[1]:=
Click for copyable input

This performs the erosion 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]=
