This paper copes with the reconstruction of accretionary growth sequence from images of biological structures depicting concentric ring patterns. Accretionary growth shapes are modeled as the level-sets of a potential function. Given an image of a biological structure, the reconstruction of the...
We propose the epiflow as a novel framework to integrate the motion and stereo epipolar geometries for the tracking of stereo matches. For a given stereo pair, spatio-temporal correspondences in the next stereo pair are established from the solution of an optimization problem that incorporates...
We aim to create systems that identify and locate objects by comparing known, 3D shapes to intensity images that they have produced. To do this we focus on verification methods that determine whether a known model in a specific pose is consistent with an image. We build on prior work that has...
Geometric approaches for filling-in surface holes are introduced and studied in this paper. The basic principle is to choose the completing surface as one which minimizes a power of the mean curvature. We interpret this principle in a level set formulation, that is, we represent the surface of...
This paper presents a novel Discrete Cosine Features (DCF) method for face recognition. The DCF method works by fusing the complementary features derived from the Discrete Cosine Transform (DCT) of the color component images in the YIQ color space. The novelty of the DCF method thus comes from...
This paper expands on the scope of correlation filters to show their usefulness for reliable face recognition. Towards that end we propose adaptive and robust correlation filters (ARCF) and describe their usefulness for reliable face authentication using recognition-by-parts strategies. ARCF...
We introduce a new approximation approach for landmark-based elastic image registration using Gaussian elastic body splines (GEBS). We formulate an extended energy functional related to the Navier equation under Gaussian forces which allows to individually weight the landmarks according to their...
