<h1>Objective</h1>
For the task of prostate segmentation, we provide two tools: 1. shape based and 2. semi-automatic random walk based. The goal is to put both algorithm into Slicer3 as command line modules.

<h1>Approach, Plan</h1>
Algorithm 1. is a Bayesian Shape based segmentation. The shape of prostates are learned and then the new image is segmented using the shapes learned. Algorithm 2. is based on the Random Walks segmentation algorithm. It need more human input but the result could be interactively improved arbitrarily close to user's expectation.

<h1>Progress</h1>

Algorithm 2. is already in the form of command line module. Algorithm 1. is also ready to be ported in. 

What we'll work on during the project week are 
1. plug both algorithms into Slicer3 without source compiled version of Slicer3; 
2. Improve the algorithm for better segmentation performance.
