Towards robustness under occlusion for face recognition
Tomas M. Borges, Teofilo E. de Campos, Ricardo de Queiroz
In this paper, we evaluate the effects of occlusions in the performance of a face recognition pipeline that uses a ResNet backbone. The classifier was trained on a subset of the Ce…
Model-Centric Volumetric Point Cloud Attributes
Ricardo L. de Queiroz, Camilo Dorea, Davi R. Freitas +2
Point clouds have recently gained interest, especially for real-time applications and for 3D-scanned material, such as is used in autonomous driving, architecture, and engineering,…
Random Paraunitary Projections
Ricardo L. de Queiroz
Transforms using random matrices have been found to have many applications. We are concerned with the projection of a signal onto Gaussian-distributed random orthogonal bases. We a…
Multi-resolution intra-predictive coding of 3D point cloud attributes
Eduardo Pavez, Andre L. Souto, Ricardo L. De Queiroz +1
We propose an intra frame predictive strategy for compression of 3D point cloud attributes. Our approach is integrated with the region adaptive graph Fourier transform (RAGFT), a m…
