On the Reproducibility of Experiments of Indexing Repetitive Document Collections
Antonio Fariña, Miguel A. Martínez-Prieto, Francisco Claude +4
This work introduces a companion reproducible paper with the aim of allowing the exact replication of the methods, experiments, and results discussed in a previous work [5]. In tha…
Space- and Time-Efficient Storage of LiDAR Point Clouds
Susana Ladra, Miguel R. Luaces, José R. Paramá +1
LiDAR devices obtain a 3D representation of a space. Due to the large size of the resulting datasets, there already exist storage methods that use compression and present some prop…
Parallel optimization of fiber bundle segmentation for massive tractography datasets
Andrea Vázquez, Narciso López-López, Nicole Labra +5
We present an optimized algorithm that performs automatic classification of white matter fibers based on a multi-subject bundle atlas. We implemented a parallel algorithm that impr…
Efficient processing of raster and vector data
Fernando Silva-Coira, José R. Paramá, Susana Ladra +2
In this work, we propose a framework to store and manage spatial data, which includes new efficient algorithms to perform operations accepting as input a raster dataset and a vecto…
Energy consumption in compact integer vectors: A study case
José Fuentes-Sepúlveda, Susana Ladra
In the field of algorithms and data structures analysis and design, most of the researchers focus only on the space/time trade-off, and little attention has been paid to energy con…
Grammar Compressed Sequences with Rank/Select Support
Alberto Ordóñez, Gonzalo Navarro, Nieves R. Brisaboa
Sequence representations supporting not only direct access to their symbols, but also rank/select operations, are a fundamental building block in many compressed data structures. S…
