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…
Objective quality assessment of medical images and videos: Review and challenges
Rafael Rodrigues, Lucie Lévêque, Jesús Gutiérrez +7
Quality assessment is a key element for the evaluation of hardware and software involved in image and video acquisition, processing, and visualization. In the medical field, user-b…
Severity classification in cases of Collagen VI-related myopathy with Convolutional Neural Networks and handcrafted texture features
Rafael Rodrigues, Susana Quijano-Roy, Robert-Yves Carlier +1
Magnetic Resonance Imaging (MRI) is a non-invasive tool for the clinical assessment of low-prevalence neuromuscular disorders. Automated diagnosis methods might reduce the need for…
Segmentation of Skeletal Muscle in Thigh Dixon MRI Based on Texture Analysis
Rafael Rodrigues, Antonio M. G. Pinheiro
Segmentation of skeletal muscles in Magnetic Resonance Images (MRI) is essential for the study of muscle physiology and diagnosis of muscular pathologies. However, manual segmentat…
