Shadows in Three-Source Photometric Stereo
Shadows are one of the most significant difficulties of the photometric stereo method. When four or more images are available, local surface orientation is overdetermined and the s...

Active Contour Segmentation with a Parametric Shape Prior: Link with the Shape Gradient
Active contours are adapted to image segmentation by energy minimization. The energies often exhibit local minima, requiring regularization. Such an a priori can be expressed as a...

Variational Textured Image Decomposition with Improved Edge Segregation
Image decomposition consists of splitting an image into two or more components. One component is piecewise smooth and models object shapes. Another component consists of the textu...

Closed surface reconstruction in X-ray tomography
We study the 3D reconstruction of a binary scene from X-ray tomographic data. In the special case of a compact and uniform object lying in a uniform background, the scene is entir...

Online Distance Recovery for a Sewer Inspection Robot
An algorithm for online distance computation based on images taken in a sewer by a robot-inspector is presented. Modern concrete sewers are made of standard cylindrical pipes sepa...
