Compcam 2012 Fall Assignment 3
Posted: November 1, 2012 Filed under: Uncategorized Leave a commentUsed the matlab code to do the edge detection. We then do region filling to create mask for foreground/background separation. Kmeans clustering method was applied to create a cartoonized photo, which is used to be the color source of final output image.
Tested on photos given, edges found:
Mask created via region filling:
Cartoonized effect via Kmeans clustering with 8 colors:
Output image (background color changed to illustrate the background/foreground separation):
Another experiment by our own photos:
Since the lighting condition, background is less controlled compared to the photos given, edges detected are more noisy. Also, some edges such as desk boundary is actually correct.
Via low-pass filtering some manually editing (e.g., for desk boundary) we get the following mask:
We again apply Kmeans clustering to get cartoonized effect (with 32 colors):
Here is the output image:

Source code can be found in the bitbucket.
Challenges: hard to take photos in position, angles that almost identical without a tripod.
