A layered method of visibility resolving in depth image-based rendering
A layered method is presented in this paper to resolve the visibility problem in depth image-based rendering. A novel three-layer representation for each reference view, i.e. the ...

A Hybrid Face Recognition Method using Markov Random Fields
We propose a hybrid face recognition method that combines holistic and feature analysis-based approaches using a Markov random field (MRF) model. The face images are divided into ...

Shape from self-calibration and Fast Marching Method
Shape-from-shading methods recover 3-D shape from intensity images. Often, Lambertian reflectance is assumed. The Lambertian assumption is attractive because it simplifies the a...

Generic Multi-scale Segmentation and Curve Approximation Method
Abstract. We propose a new complete method to extract significant description(s) of planar curves according to constant curvature segments. This method is based (i) on a multi-sca...

The Problem of Fragile Feature Subset Preference in Feature Selection Methods and a Proposal of Algorithmic Workaround
Abstract—We point out a problem inherent in the optimization scheme of many popular feature selection methods. It follows from the implicit assumption that higher feature selecti...
