A Novel Approach for Fast Action Recognition using Simple Features (2008)
Ragheb, Hossein, Velastin, Sergio, Remagnino, Paolo, Ellis, Tim
We propose a new method for human action recognition from video streams that is fast and robust to random noise, partial occlusions and large changes in camera views. We extract features in the...

Independent Viewpoint Silhouette-based Human Action Modelling and Recognition (2008)
Orrite, Carlos, Martínez, Francisco, Herrero, Elías, Ragheb, Hossein, Velastin, Sergio
This paper addresses the problem of silhouette-based human action modelling and recognition independently of the camera point of view. Action recognition is carried out by comparing a 2D motion...

Diuse Re ectance Models for Rough Surfaces: A Geometrical Study for Shape-from-Shading (2007)
Hossein Ragheb, Edwin R. Hancock
This paper describes how surface shape can be recovered from rough surfaces using the Oren and Nayar model. The idea underpinning the method is to use the Oren and Nayar model to perform Lambertian...
Surface Radiance Correction for Shape from Shading (2005)
Hossein Ragheb, Edwin R. Hancock
It is well known that many surfaces exhibit reflectance that is not well modelled by Lambert’s law. This is the case not only for surfaces that are rough or shiny, but also those that are matte and...
Improved shape from shading using non-Lambertian reflectance models / (2004)
Thesis (Ph.D.)--University of York, 2004.
Abstract Darboux smoothing for shape-from-shading (2002)
Hossein Ragheb, Edwin R. Hancock
This paper describes a new surface normal smoothing process which can be used in conjunction with shape-fromshading. Rather than directly smoothing the surface normal vectors, we exert control over...
Separating Lambertian and Specular Reflectance Components using Iterated Conditional Modes (2001)
Hossein Ragheb, Edwin. R. Hancock
In this paper we address the problem of separating Lambertian and specular reflection components in order to improve the quality of surface normal information recoverable using shape-from-shading....
