Richard Radke

Assistant Professor


investigators

Department Affiliation:
Department of Electrical, Computer, & Systems Engineering

Education:
Ph.D., Princeton University, Electrical Engineering
M.A., Princeton University, Electrical Engineering
M.A., Rice University, Computational and Applied Mathematics
B.A., Rice University, Mathematics, Computational and Applied Mathematics (dual)


Research Areas:

  • Distributed, active processing on hundred-camera networks
  • 3D Modeling and tracking from distributed mobile sensors
  • Computer vision, machine learning, and optimization for intensity-modulated radiotherapy
  • Change detection and understanding in image and video sequences
  • Magnetic field mapping via heavy ion beam spectral imaging

Research Summary:

  • I am interested in computer vision problems that occur in networks of a large number (tens to hundreds) of cameras dispersed throughout an environment. We have developed distributed solutions for determining visual overlap and camera calibration in large dynamic camera networks, which provide the basis for higher-level vision problems (e.g. change detection, multi-object tracking, image-based query, or view synthesis).
  • I also collaborate on research involving 3D data representation, registration, and integration of range and visual imagery. I am particularly interested in change detection in range imagery and joint fusion of EO/LiDAR data.
  • I am also particularly interested in computer vision and machine learning problems related to intensity modulated radiotherapy (IMRT), an exciting new technology for cancer treatment. One project involves developing computer vision algorithms to aid in the automatic segmentation of organs from 3-D CT scans acquired immediately prior to radiation treatment. A second project investigates the relationship between a patient's body/organ geometry and the multiple radiation beams that are used to treat their cancer. We have investigated both the breast and prostate. These projects include collaborations with medical physicists at Memorial Sloan-Kettering Cancer Center and Massachusetts General Hospital.
