Project Proposal: A Multiresolution Stochastic Approach for Shape From Shading Using Intensity Gradient Constraint
نویسندگان
چکیده
The objective of this project is the study of Shape from Shading (SfS) problem in a variational framework. Among the other shape recovery methods, SfS is employed to obtain three-dimensional shape using spatial variations of brightness in an image. In this study, SfS problem will be addressed as an energy minimization problem. A constraint which establishes a connection between intensity gradient space and solution surface is imposed into the corresponding energy functional for the first time in a direct energy minimization scheme. A hybrid approach which combines the efficiency of deterministic methods and accuracy of stochastic methods is proposed in a multiresolution domain for the solution of this problem.

A Multiresolution Approach for Shape from Shading Coupling Deterministic and Stochastic Optimization
Shape from shading is an ill-posed inverse problem for which there is no completely satisfactory solution in the existing literature. In this paper, we address shape from shading as an energy minimization problem. We first show that the deterministic approach provides efficient algorithms in terms of CPU time, but reaches its limits since the energy associated with shape from shading can contai...
متن کاملShape from Intensity Gradient - Systems, Man and Cybernetics, Part A, IEEE Transactions on
Unlike existing global shape-from-shading (SFS) algorithms which involve the brightness constraint in their formulation, we propose a new SFS algorithm which replaces the brightness constraint with an intensity gradient constraint. This is a global approach which obtains the solution by the minimization of an error function over the entire image. Through the linearization of the gradient of the...
متن کاملEstimation of illuminant direction, albedo, and shape from shading
A robust approach to recovery of shape from shading information is presented. Assuming uniform albedo and Lambertian surface for the imaging model, we first present methods for the estimation of illuminant direction and surface albedo. The illuminant azimuth is estimated by averaging local estimates. The illuminant elevation and surface albedo are estimated from image statistics. Using the esti...

This paper extends the MRF formulation approach [6] for solving the shape from shading problem. Our method uses simulated annealing Gibbs sampling to minimize a lattice energy for an MRF formulation which characterizes the Shape from Shading (SFS) problem under Lambertian reflectance conditions. We explore a spatial multi-resolution approach which refines the digital elevation map of the surfac...
متن کاملFace Shape Recovery from a Single Image View
The problem of acquiring surface models of faces is an important one with potentially significant applications in biometrics, computer games and production graphics. For such task, the use of shape-from-shading (SFS) is appealing since it is a non-invasive method that mimics the capabilities of the human visual system. In this thesis, our interest lies on the recovery of facial shape from singl...
