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.

Specific requirements

Build requirements

A C++ compiler compliant with C++11 or above
The JPEG library installed and configured
The PNG library installed and configured.

Execution requirements

convolve2d expects to find an image called src_view.png in the current directory.
