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…
A 3D Motion Vector Database for Dynamic Point Clouds
André L. Souto, Ricardo L. de Queiroz, Camilo Dorea
Due to the large amount of data that point clouds represent and the differences in geometry of successive frames, the generation of motion vectors for an entire point cloud dataset…
Example-based super-resolution for point-cloud video
Diogo C. Garcia, Tiago A. Fonseca, Ricardo L. de Queiroz
We propose a mixed-resolution point-cloud representation and an example-based super-resolution framework, from which several processing tools can be derived, such as compression, d…
