• Research on similarity measures for image database (e.g., face, textures) indexing and content-based
retrieval, image coding using wavelets, VQ and space-filling curves; Involved in building an image-processing research laboratory with Elec. & Comp. Engg. Deptt., UCSD.
• Collaborated in research with UCSD Dept. of Opthalmology in automated structural analysis (STARE)
and indexing of retinal image database. Developed appropriate tools for disease/manifestation paradigm.
