Almost Done!!

i think basicly my work is already about 85%
Point Operation :
-Negative
-GreyScale
-Quantisizing
-Mirror
-Brighten
-Contrast
-Black and White
Neighbourhood Operation:
-Blur
-Edge Detection
-Pencil

now the problem i hate the most is, how you actually do the convolveOperation.
to solve that think that instead of pixel,your middle point of mask(3*3) is who travel the image.
in looping you need to travel from you mask as well.

and the last part i think it's about histogram.
Wish me luck :)
