In this video, various filters and edge detection techniques are covered. They are applied on an image and the output by applying various filters is explained.
Code:
a = imread('color.jpg');
subplot(2,3,1), imshow(a);
b = rgb2gray(a);
subplot(2,3,2), imshow(b);
h = ones(6,6)/36;
c = imfilter(b,h);
subplot(2,3,3), imshow(c);
h = [1 0 -1; 2 0 -2; 1 0 -1];
d = imfilter(b,h);
subplot(2,3,4), imshow(d);
e = edge(b,'canny');
imshow(e)
