Abstract
The recovery of depth from defocus involves calculating the depth of various points in a scene by modeling the effect that the focal parameters of the camera have on images acquired with a small depth of field. We propose a method that, instead of analyzing an image region in isolation, uses a block shift-variant interactive blur model to account for the interaction among neighboring subimages. Simulation results are presented on the performance of the model Author(s) Rajagopalan, A.N. Dept. of Electr. Eng., Indian Inst. of Technol., Bombay, India Chaudhuri, S.Keywords
