24. Reconstruction: Reconstruction from projections. Used in constructing 3D data from 2D projections in computer tomography. Image representation using features: Low level representations using color, texture, shape, motion, etc. High level features for recognitions; e.g., facial features. Recognition and scene understanding Image Processing (cont.)
