Lab Assignment You are allowed to use whatever language you are comfortable with and whatever maxflow (or mincut) implementation available. The framework provided for the lab is in C++.

Lab Assignment Setup and solve some maxflow problems. Try this problem as well (HINT: For terminal edges that don’t exist, you can set the weight to 0) FG BG

Problem from last week: If you wanted to setup the following problem, where A is the source, and C is the sink … A B D CE

You could convert the problem as follows. Use a 0 weight for non-existing reverse edges. A B D CE FG BG

HW 5: Graph Cuts Segmentation The goal of the assignment is to introduce you to graphcuts segmentation. You will be required to set up a graphcut problem. Use Graph-Cuts segmentation to make a postcard.

HW 5: Graph Cuts Segmentation 1. Snap a picture of yourself (or use lena.jpg), draw foreground and background seeds.

HW 5: Graph Cuts Segmentation 2. Setup the graph problem for an image and solve. 3. With the segmented results, overlay the resulting image on a background of your choosing (or use backdrop.jpg) Submit a zip file containing your code file(s) and your result image.
