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

This performs a mean filter:

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

Use CUDAImageConvolve on a grayscale image with a Sobel mask to detect vertical edges:

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

Using CUDAImageConvolve on a graphics object will automatically rasterize the graphic:

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