Geometrical descriptors for human face morphological analysis and recognition
The human eye, connected to the brain, gives people the possibility to immediately, automatically and exactly recognize one person from another. A main aim is obviously to “copy” this recognition mechanism of the brain and to use it as a means for face recognition. Since the human recognition happens through an automatic “authentication” of facial shape and features, this face study is totally ...
متن کامل3D face recognition: An automatic strategy based on geometrical descriptors and landmarks
In the last decades, several three‐dimensional face recognition algorithms have been thought, designed, and assessed. What they have in common can be hardly said, as they differ in theoretical background, tools, and method. Here we propose a new 3D face recognition algorithm, entirely developed in Matlab®, whose framework totally comes from Differential Geometry. Firstly, 17 soft‐tissue landmar...
متن کاملFace recognition using 3D surface-extracted descriptors
The discriminating power of three dimensional (3D) descriptors extracted from 3D human face surfaces is analyzed. An automatic face recognition system using different subsets of the descriptor set has been implemented and tested. We used 420 3D-facial meshes belonging to 60 individuals, including views presenting light rotations and facial expressions, for the experiments. An HK segmentation (b...
متن کاملSelection and Extraction of Patch Descriptors for 3D Face Recognition
In 3D face recognition systems, 3D facial shape information plays an important role. 3D face recognizers usually depend on point cloud representation of faces where faces are represented as a set of 3D point coordinates. In many of the previous studies, faces are represented holistically and the discriminative contribution of local regions are assumed to be equivalent. In this work, we aim to d...
متن کاملTopological Descriptors for 3D Surface Analysis
We investigate topological descriptors for 3D surface analysis, i.e. the classification of surfaces according to their geometric fine structure. On a dataset of high-resolution 3D surface reconstructions we compute persistence diagrams for a 2D cubical filtration. In the next step we investigate different topological descriptors and measure their ability to discriminate structurally different 3...
