Pre-requisite: EE-610; Imaging model and geometry: scene radiance and image irradiance, reflectance model of a surface, Lambertian and specular reflectance, photometric stereo; Ill-posedness of vision problems: regularization theory; Shape from shading, structured light, and texture. Optical flow, structure from motion, and recursive motion analysis. Stereo vision and correspondence problem; Depth analysis using real-aperture camera: depth from defocused images; MRF approach to early vision problems:(shape from shading, matching, stereo and motion), Image texture analysis; Introduction to image understanding; Integrated vision, sensor fusion.
