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.

Progress

1) Discussed applications of 3D SIFT-Rank

  • Analyzing COPD - lung CT - Raul San Jose Estepar
  • Identifying similar cases - general MR/CT/US - Tobias Penzkofer
  • Infant brain analysis - brain MR - Steve Pieper
  • Prostate segmentation - MR/US - Andrey Federov, Salvatore Scaramuzzino
  • Astronomical galaxy classification - radio data cube (lambda=21cm) - Davide Punzo

2) Coding for kernel regression framework (C++)
