CUDABoxFilter
This feature is not supported on the Wolfram Cloud.

CUDABoxFilter[img,r]
gives the box filter of img with radius r.

CUDABoxFilter[list,r]
gives the box filter of list with radius r.

CUDABoxFilter[mem,r]
gives the box filter of mem with radius r.

DetailsDetails

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

This finds the sum of values in a neighborhood of a list:

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

CUDABoxFilter on a graphics object will automatically rasterize the graphic:
