Recovering Planar Homographies between 2D Shapes
Images taken from different views of a planar object are related by planar homography. Recovering the parameters of such transformations is a fundamental problem in computer vis...

Robust Estimation of Albedo for Illumination-invariant Matching and Shape Recovery
In this paper, we propose a non-stationary stochastic filtering framework for the task of albedo estimation from a single image. There are several approaches in literature for alb...

Robust 2D Shape Estimation of Moving Objects Considering Spatial and Temporal Coherency in One Map Detection Rule
In this paper an algorithm for 2D shape estimation of moving objects is proposed, which reduces the estimation error compared to the ISO/MPEG-4 reference. The improvement is achie...

Cortical Shape Analysis in the Laplace-Beltrami Feature Space
For the automated analysis of cortical morphometry, it is critical to develop robust descriptions of the position of anatomical structures on the convoluted cortex. Using the eigen...

Estimation of 3D Shape of Warped Document Surface for Image Restoration
While scanning pages from a thick, bound book, there are two sources of distortion in the document images: 1) shade along the book `spine', and 2) warping of the book surface...
