Subjective Evaluation of Low Distortion Coded Light Fields with View Synthesis
Daniela Saraiva, Joao Prazeres, Manuela Pereira +1
Light field technology is a powerful imaging method that captures both the intensity and direction of light rays in a scene, enabling the reconstruction of 3D information and suppo…
Point Cloud Objective Quality: Benchmarking Features and Quality Evaluation
Joao Prazeres, Rafael Rodrigues, Manuela Pereira +1
Full-reference point cloud objective metrics are currently providing very accurate representations of perceptual quality. These metrics are usually composed of a set of features th…
Quality Analysis of the Coding Bitrate Tradeoff Between Geometry and Attributes for Colored Point Clouds
Joao Prazeres, Rafael Rodrigues, Manuela Pereira +1
Typically, point cloud encoders allocate a similar bitrate for geometry and attributes (usually RGB color components) information coding. This paper reports a quality study conside…
Performance analysis of Deep Learning-based Lossy Point Cloud Geometry Compression Coding Solutions
Joao Prazeres, Rafael Rodrigues, Manuela Pereira +1
The quality evaluation of three deep learning-based coding solutions for point cloud geometry, notably ADLPCC, PCC GEO CNNv2, and PCGCv2, is presented. The MPEG G-PCC was used as a…
Subjective Quality Evaluation of Point Clouds Using a Head Mounted Display
Joao Prazeres, Rafael Rodrigues, Manuela Pereira +1
This paper reports on a subjective quality evaluation of static point clouds encoded with the MPEG codecs V-PCC and G-PCC, the deep learning-based codec RS-DLPCC, and the popular D…
Fast and Efficient Lenslet Image Compression
Hadi Amirpour, Antonio Pinheiro, Manuela Pereira +1
Light field imaging is characterized by capturing brightness, color, and directional information of light rays in a scene. This leads to image representations with huge amount of d…
