Two-dimensional BRDF estimation from polarisation (2008)
Journal Article
This paper presents a novel technique for reflectance function (BRDF) estimation, which uses polarisation information and photometric stereo. The first stage of the technique is standard and involves the acquisition of polarisation information (angle... Read More about Two-dimensional BRDF estimation from polarisation.
Shape estimation using polarization and shading from two views (2007)
Journal Article
This paper presents a novel method for 3D surface reconstruction that uses polarization and shading information from two views. The method relies on polarization data acquired using a standard digital camera and a linear polarizer. Fresnel theory is...

Recovery of surface orientation from diffuse polarization (2006)
Journal Article
When unpolarized light is reflected from a smooth dielectric surface, it becomes partially polarized. This is due to the orientation of dipoles induced in the reflecting medium and applies to both specular and diffuse reflection. This paper is concer...

High-precision polarization measurements and analysis for machine vision applications
Presentation / Conference Contribution
Polarization is a source of information that is steadily attracting attention in the field of computer vision due to its ability to tap into information not readily available in standard colour or greyscale cameras. Unfortunately, most existing data... Read More about High-precision polarization measurements and analysis for machine vision applications.
