Hi
I have two queries to do with Image Processing.
1) I have an array of values which represent an image. The problem is that I need to change the contrast. How do I calculate the new values of the array.
2) I have created a 3x3 mask to detect edges. How do I apply the values in the mask to the values in the array. The following is what the mask looks like:
m1 m2 m3
m4 m5 m6
m7 m8 m9
I what to change the value of the pixel under m5 but I don't know how to apply the other values to it. This is just one of two masks.
Thank you
