Objective

To create an end-to-end Lupus lesion segmentation and analysis pipeline that can work in both an automated and semi-supervised fashion.

See our Roadmap for more details.

Approach, Plan

Our approach involves the combination of morphometric features with a non-linear classifier in order to capture more of the gestalt properties a human rater uses when segmenting Lupus lesions.

Our plan for the project week is to:

• Work with Steve Pieper to implement the wizard interface to the lesion analysis module to make the segmentation process easier.
• Integrate the output of the lesion analysis module with change tracker to allow for longitudinal analysis.
• Refactor the lesion analysis code and integrate it with the Slicer code repository so it is built with Slicer.
