SHAPE FROM COLOR CONSISTENCY USING NODE CUT (2008)
Ning Xu, Tianli Yu, Narendra Ahuja
In this paper, we present a method to estimate the shape of a three dimensional (3D) object by enforcing color consistency in the views of object points in images acquired from different viewpoints....
Shape Regularized Active Contour using Iterative Global Search and Local Optimization ∗ (2008)
Recently, nonlinear shape models have been shown to improve the robustness and flexibility of segmentation. In this paper, we propose Shape Regularized Active Contour (ShRAC) that incorporates...

and generate the final composite image (right). Abstract We present a novel image-based modeling technique which allows simultaneous estimation of illumination, diffuse, and specular albedo maps...
Shape and view independent reflectance map from multiple views (2004)
Tianli Yu, Ning Xu, Narendra Ahuja
Abstract. We consider the problem of estimating the 3D shape and reflectance properties of an object made of a single material from a calibrated set of multiple views. To model reflectance, we...
N.: Recovering shape and reflectance model of nonlambertian objects from multiple views (2004)
Tianli Yu, Ning Xu, Narendra Ahuja
This paper proposes an algorithm to simultaneously estimate both the 3D shape and parameters of a surface reflectance model from multiple views of an object made of a single material. The algorithm...
