Objective
We will continue developping and testing the white matter lesion segmentation algorithm implemented using ITK. The goal is to have an initial version ready by the end of the week that can be distributed within NA-MIC community for more extensive testing.
Approach, Plan
We will develop a Slicer module for the white matter lesion segmentation algorithm. Base line results and test will be generated.
Progress
Since winter project week in Utah, we have developed/implemented WML segmentation algorithm using ITK classes. Subtasks implemented includes: 1. a skull stripping algorithm working on T1 weighted images; 2. a fuzzy clustering algorithm for tissue segmentation; 3. a parametric modle for gain field correction. All these are implemented using ITK. The training step uses AdaBoost and the segmenation step uses a support vector machine.
