Shape-from-shading and Photometric Stereo Methods: a Review
نویسنده
چکیده
Most of the existing works view the shapefrom-shading problem as equivalent to a non-linear first-order partial differential equation in surface elevation. Recently, there is a new approach to this problem, namely the shape-from-shading using the heat equation. This paper reviews several works either using the first or the second approach. The previous approach is also implemented in solving the photometric stereo which is an extension of shape-from-shading problem. This paper also reviews the 2-D Leap-Frog algorithm for solving photometric stereo problem.

متن کاملShading Based 3D Shape Recovery in the Presence of Shadows
Shadows usually cause various problems in three-dimensional shape recovery and measurement methods. In particular shading based approaches such as shape-from-shading or the photometric stereo method produce no or wrong results if the shadows are not treated appropriately. We show how information extracted from shadows can be employed to reduce the problems caused by them. This is done for multi...
متن کاملA Shape-From-Shading Algorithm Using Photometric Stereo
We present a simple shape-from-shading algorithm that uses two shading images. This enables us to estimate more accurate shapes of objects without any special constraints or conditions than the existing photometric stereo algorithms. The Jacobi’s iterative method is applied to the difference between the image and the reflectance function represented as a function of three depth parameters for e...
متن کاملShape From Shading
Shape From Shading is the process of computing the threedimensional shape of a surface from one image of that surface. Contrary to most of the other three-dimensional reconstruction problems (for example, stereo and photometric stereo), in the Shape From Shading problem, data are minimal (we use a single image!). As a consequence, this inverse problem is intrinsically a difficult one. In this c...
متن کاملUsing Photometric Stereo for Face Recognition
This paper aims to review the technique of Photometric Stereo (PS), with specific application to face recognition. PS is a method to rapidly estimate the three-dimensional geometry of a face (or any other Lambertian-like object) using several images with an identical viewpoint but varied illumination directions. The contributions of this paper are to (1) summarise the pros and cons of PS compar...
