Emotion recognition in talking-face videos using persistent entropy and neural networks
Eduardo Paluzo-Hidalgo, Guillermo Aguirre-Carrazana, Rocio Gonzalez-Diaz
The automatic recognition of a person's emotional state has become a very active research field that involves scientists specialized in different areas such as artificial intellige…
Topological signature for periodic motion recognition
Javier Lamar-Leon, Rocio Gonzalez-Diaz, Edel Garcia-Reyes
In this paper, we present an algorithm that computes the topological signature for a given periodic motion sequence. Such signature consists of a vector obtained by persistent homo…
Topological Tracking of Connected Components in Image Sequences
Rocio Gonzalez-Diaz, Maria-Jose Jimenez, Belen Medrano
Persistent homology provides information about the lifetime of homology classes along a filtration of cell complexes. Persistence barcode is a graphical representation of such info…
Persistent-homology-based gait recognition
J. Lamar-Leon, Raul Alonso-Baryolo, Edel Garcia-Reyes +1
Gait recognition is an important biometric technique for video surveillance tasks, due to the advantage of using it at distance. In this paper, we present a persistent homology-bas…
Removal and Contraction Operations in D Generalized Maps for Efficient Homology Computation
Guillaume Damiand, Rocio Gonzalez-Diaz, Samuel Peltier
In this paper, we show that contraction operations preserve the homology of D generalized maps, under some conditions. Removal and contraction operations are used to propose an…
3D Well-composed Polyhedral Complexes
Rocio Gonzalez-Diaz, Maria-Jose Jimenez, Belen Medrano
A binary three-dimensional (3D) image is well-composed if the boundary surface of its continuous analog is a 2D manifold. Since 3D images are not often well-composed, there are…
