Visual Small Body Navigation: Using visual odometry, implemented an application for keeping relative position to a comet. Integrated system with a model comet and 5dof robotic arm with digital camera.
MSL Hazcam Stereo Coverage research: Created and executed a test plan for determining the stereo depth coverage as a function of height and baseline for the MSL Hazcams.
Pinpoint Landing: Implemented freq domain normalized correlation to match lander descent images with larger registered map images to find absolute position to facilitate navigation during entry and landing.
MSL Rover Navigation Validation: Using FIDO research rover to validate the stereo vision/path planner system Gestalt.
UCSD CSE Department, La Jolla, CA 9/01-12/01
Spectral Segmentation research: Used eigenvector techniques to find object segmentation in both still frames and motion video.
Path 1 Network Tech. Inc., La Jolla, CA 11/00-9/01
Video-over-IP switch: Implemented Tcl/Tk tools and wrote SNMP network management software for VOIP switch.
