Quantifying the regeneration of bone tissue in biomedical images via Legendre moments
(2013-10-21)We investigate the use of Legendre moments as biomarkers for an efficient and accurate classification of bone tissue on images coming from stem cell regeneration studies. Regions of either existing bone, cartilage or ... -
Real-Time Unsupervised Object Localization on the Edge for Airport Video Surveillance.
(2023)Object localization is vital in computer vision to solve object detection or classification problems. Typically, this task is performed on expensive GPU devices, but edge computing is gaining importance in real-time ... -
Reducing overheads of dynamic scheduling on heterogeneous chips
(arXiv.org (Cornell University Library), 2015-01-19)In recent processor development, we have witnessed the integration of GPU and CPUs into a single chip. The result of this integration is a reduction of the data communication overheads. This enables an efficient collaboration ... -
Reorganización de matrices en algoritmos de barrido radial sobre Modelos Digitales del Terreno

Scalability Analysis of Signatures in Transactional Memory Systems
(2014-10-29)Signatures have been proposed in transactional memory systems to represent read and write sets and to decouple transaction conflict detection from private caches or to accelerate it. Generally, signatures are implemented ... -
A scheduling theory framework for GPU tasks efficient execution
(2018-07-16)Concurrent execution of tasks in GPUs can reduce the computation time of a workload by overlapping data transfer and execution commands. However it is difficult to implement an efficient run- time scheduler ... -
Simplified Floating-Point Units for High Dynamic Range Image and Video Systems
(2015-06-29)The upcoming arrival of high dynamic range image and video applications to consumer electronics will force the utilization of floating-point numbers on them. This paper shows that introducing a slight modification on ... -
Siting Multiple Observers for Maximum Coverage: An Accurate Approach
