Image processing custom filter 7 by 7
- by ladiesMan217
Lets say I have a 7 by 7 neighborhood around a pixel that looks like this
1 2 3 4 5 6 7
8 9 10 11 12 13 14
15 16 17 18 19 20 21
22 23 24 25 26 27 28
29 30 31 32 33 34 35
36 37 38 39 40 41 42
43 44 45 46 47 48 49
and I wanna filter the above by replacing the pixel p by the average of those pixels whose value lie in the range -10<=p_value <=10.
I am new to image processing and I think in this case p_value is 25 and around 25 that are many pixel values in that range but don't exactly know to construct a convolution filter out of it.
