For cs542, Machine Learning I implemented a image depixelator to clean up images. You can see the result below:
| Original | Processed |
|---|---|
 |

To run just run hw5sol.m in matlab.
I was able to get an accuracy of 99.45% using the following params.
| h | b | n |
|---|---|---|
| -.01 | 5 | 3 |
I was able to implement a similar algorithm for part b on grayscale images. Instead of flipping a pixel, I either incremented it or decremented it, or left it the same. You can see the results below:
| Original | Processed |

There's no definition of accuracy here, I'll let you decide which image looks better.
To run, run hw5B.m in the matlab interpreter.
