A Fuzzy-Neural Approach for Estimation of Depth Map using Focus
Depth map is used for recovery of three dimensional structure of the object which is required in many high level vision applications. In this paper, we present a new algorithm for the estimation of depth map for three dimensional shape recovery. This algorithm is based on Fuzzy-Neural approach using...
