CV-HW-2

Given an image, filter the image with cross-correlation and convolution, respectively.

Cross-correlation:

1	2	2	3	4	5
2	3	4	5	6	7
3	3	4	4	5	6
4	5	6	7	8	9

Filter:

1	2	1
0	0	0
-1	-2	-1

Result:

-6	-6	5	-4
-8	-8	-8	-8

Convolution:

1	2	2	3	4	5
2	3	4	5	6	7
3	3	4	4	5	6
4	5	6	7	8	9

Filter:

1	2	1
0	0	0
-1	-2	-1

Result:

6	6	-5	4
8	8	8	8
