# Convolution (2d kernel)
|
||
|
|
|
||
|
|
2d kernel convolution capabilities in GIL are demonstrated by the program `convolve2d`, compiled from the sources `example/convolve2d.cpp`.
|
||
|
|
|
||
|
|
## Synopsis
|
||
|
|
|
||
|
|
`convolve2d`
|
||
|
|
|
||
|
|
The program doesn't take any argument on the command line.
|
||
|
|
|
||
|
|
`convolve2d` expects to find an image called `src_view.png` in the current directory, and produces two images in return, where the filters have been applied: `out-convolve2d.png` and `out-convolve_option_extend_zero.png`
|
||
|
|
|
||
|
|
Note that the user is expected to press a key to end the program.
