Low Complexity Learning-based Lossless Event-based Compression
Ahmadreza Sezavar, Catarina Brites, Joao Ascenso
Event cameras are a cutting-edge type of visual sensors that capture data by detecting brightness changes at the pixel level asynchronously. These cameras offer numerous benefits o…
Learning-based Lossless Event Data Compression
Ahmadreza Sezavar, Catarina Brites, Joao Ascenso
Emerging event cameras acquire visual information by detecting time domain brightness changes asynchronously at the pixel level and, unlike conventional cameras, are able to provid…
Evaluation of Sampling Algorithms for a Pairwise Subjective Assessment Methodology
Shima Mohammadi, Joao Ascenso
Subjective assessment tests are often employed to evaluate image processing systems, notably image and video compression, super-resolution among others and have been used as an ind…
Perceptual impact of the loss function on deep-learning image coding performance
Shima Mohammadi, Joao Ascenso
Nowadays, deep-learning image coding solutions have shown similar or better compression efficiency than conventional solutions based on hand-crafted transforms and spatial predicti…
A Point-to-Distribution Joint Geometry and Color Metric for Point Cloud Quality Assessment
Alireza Javaheri, Catarina Brites, Fernando Pereira +1
Point clouds (PCs) are a powerful 3D visual representation paradigm for many emerging application domains, especially virtual and augmented reality, and autonomous vehicles. Howeve…
