| Apr 13, 2018 at 14:47 | comment | added | MeteHan | I check the rows and columns going out of bounds with different if statements. So if a columns value is negative, I append zeros to the temp array. Adding zeros in the situation of an out bound, is a common approach. And if row value is not negative , I check the column value. And append zeros if out of bounds again. And about "i+z-indexer", with this way I put the current pixel in the hotspot(basically center of the array) and I check its surrounding pixels. For 3x3 median filter, lets say we got the [0][0] pixel. So program will check [-1][-1], [-1][0], [-1][1], [0][-1], [0][0], [0][1] so on | |
| Apr 13, 2018 at 14:40 | comment | added | Peilonrayz♦ | could you answer my second question? I don't really understand how you handle those median filters going out of bounds. | |
| Apr 13, 2018 at 14:37 | comment | added | MeteHan | Sure, Median filter is usually used to reduce noise in an image. My code basically takes the array of the image which is corrupted by salt and pepper noise and remove the noise. I loop through "filter_size" because there are different sized median filters, like 3x3, 5x5. So there is more pixels that need to be considered. You can take a look at the GitHub repo, github.com/MeteHanC/Python-Median-Filter | |

Your code doesn't make the complete sense to me. Could you explain a little what it does? Why do you loop through filter_size on two of the three options in the for z in range(filter_size) loop?
