Depth Retrieval Based on Optical Defocus of Imaging System

摘要：

A novel method based on optical defocus of imaging system is presented for the estimation of the depth of the 3D scene. Firstly, optical defocus is described using the oriented heat-flows equation based on curvature driven. Secondly, the depth retrieval problem is translated into the minimum problem of energy functional with total variation regularization. Finally, the gradient flow is used to seek the optimal solution. The retrieval of focus image and the excess restrictions are avoided. Experimental result shows that better depth result can be obtained.
