NaviFormer: A Deep Reinforcement Learning Transformer-like Model to Holistically Solve the Navigation Problem
Daniel Fuertes, Andrea Cavallaro, Carlos R. del-Blanco +2
Path planning is usually solved by addressing either the (high-level) route planning problem (waypoint sequencing to achieve the final goal) or the (low-level) path planning proble…
Multi-stage Planning for Multi-target Surveillance using Aircrafts Equipped with Synthetic Aperture Radars Aware of Target Visibility
Daniel Fuertes, Carlos R. del-Blanco, Fernando Jaureguizar +2
Generating trajectories for synthetic aperture radar (SAR)-equipped aircraft poses significant challenges due to terrain constraints, and the need for straight-flight segments to e…
Energy- and Quality-Aware Video Request Policy for Wireless Adaptive Streaming Clients
César Díaz, Antonio Fernández, Fernando Sacristán +1
We present a straightforward, non-intrusive adaptive bit rate streaming segment quality selection policy which aims at extending battery lifetime during playback while limiting the…
XLR (piXel Loss Rate): a Lightweight Indicator to Measure Video QoE in IP Networks
César Díaz, Pablo Pérez, Julián Cabrera +2
A novel Key Quality Indicator for video delivery applications, XLR (piXel Loss Rate), is defined, characterized, and evaluated. The proposed indicator is an objective measure that…
Perceptually Equivalent Resolution in Handheld Devices for Streaming Bandwidth Saving
Mateo Cámara, César Díaz, Juan Casal +2
We present the description, results, and analysis of the experiments conducted to find the equivalent resolution associated with handheld devices. That is, the resolution from whic…
Application-Layer FEC Scheme Configuration Optimization via Hybrid Simulated Annealing
César Díaz, Julián Cabrera, Fernando Jaureguizar +1
An optimization technique based on an adapted combination of simulated annealing (SA) and tabu search (TS) is presented. This method aims at finding near-optimal unequal error prot…
A Video-Aware FEC-Based Unequal Loss Protection System for Video Streaming over RTP
César Díaz, Julián Cabrera, Fernando Jaureguizar +1
A video-aware unequal loss protection (ULP) system for protecting RTP video streaming in bursty packet loss networks is proposed. Considering the relevance of the frame, the state…
Methodology for accurately assessing the quality perceived by users on 360VR contents
Lara Muñoz, César Díaz, Marta Orduna +4
To properly evaluate the performance of 360VR-specific encoding and transmission schemes, and particularly of the solutions based on viewport adaptation, it is necessary to conside…
Video Multimethod Assessment Fusion (VMAF) on 360VR contents
Marta Orduna, César Díaz, Lara Muñoz +3
This paper describes the subjective experiments and subsequent analysis carried out to validate the application of one of the most robust and influential video quality metrics, Vid…
Event-based Vision meets Deep Learning on Steering Prediction for Self-driving Cars
Ana I. Maqueda, Antonio Loquercio, Guillermo Gallego +2
Event cameras are bio-inspired vision sensors that naturally capture the dynamics of a scene, filtering out redundant information. This paper presents a deep neural network approac…
Optimal Piecewise Linear Function Approximation for GPU-based Applications
Daniel Berjón, Guillermo Gallego, Carlos Cuevas +2
Many computer vision and human-computer interaction applications developed in recent years need evaluating complex and continuous mathematical functions as an essential step toward…
Optimal polygonal L1 linearization and fast interpolation of nonlinear systems
Guillermo Gallego, Daniel Berjón, Narciso García
The analysis of complex nonlinear systems is often carried out using simpler piecewise linear representations of them. A principled and practical technique is proposed to linearize…
