C++11 Convolution

Convolution Image convolution is one the easiest techniques to learn in computer vision and it's a technique that illustrates the power of local feature detection better than weeks of lecture. In principle, convolution involves nothing more than repeatedly applying an NxN matrix to a pixel and its neighbors. Depending on the matrix scalars several different effects can be achieved: Blur Edge Detection <--- Let's focus on this Sharpen Edge detection is one of the fundamental…
