Project Description

Objective

• This project will investigate the use of 3D SIFT-RANK image features for organizing and deriving information from 3D medical image volumes.
• Technology: invariant feature extraction, descriptor representation.
• Application domains: registration, segmentation, classification.
• Image domains: lung CT, brain MR, prostate and brain ultrasound.
• Clinical use case scenarios: chronic obstructive pulmonary disease, Alzheimer's disease, cancer.

Approach, Plan

• Discussion and documentation
• Algorithms: fast KNN methods, hashing, robust estimation (RANSAC, Hough transform).
• Mathematical formalisms: probabilistic inference, kernel methods, manifold learning.
