Edge Detection

It is interesting to note that while the convolution filter does identify the line it also picks up on a lot of speckles that are not really desired as it causes noise in the resulting image.

Also note that the detected lines are quite faint and sometimes even broken. This is largely due to the small (3x3) neighborhood that the convolution filter looks at. It is easy to see a very large difference between the line and the tile from a global point of view (as how you and I look at the images) but from the image pixel point of view it is not as easy. To get a better result we need to perform some modifications to our current operations.
