A framework to compare music generative models using automatic evaluation metrics extended to rhythm
Sebastian Garcia-Valencia, Alejandro Betancourt, Juan G. Lalinde-Pulido
To train a machine learning model is necessary to take numerous decisions about many options for each process involved, in the field of sequence generation and more specifically of…
Sequence Generation using Deep Recurrent Networks and Embeddings: A study case in music
Sebastian Garcia-Valencia, Alejandro Betancourt, Juan G. Lalinde-Pulido
Automatic generation of sequences has been a highly explored field in the last years. In particular, natural language processing and automatic music composition have gained importa…
Egoshots, an ego-vision life-logging dataset and semantic fidelity metric to evaluate diversity in image captioning models
Pranav Agarwal, Alejandro Betancourt, Vana Panagiotou +1
Image captioning models have been able to generate grammatically correct and human understandable sentences. However most of the captions convey limited information as the model us…
Static force field representation of environments based on agents nonlinear motions
Damian Campo, Alejandro Betancourt, Lucio Marcenaro +1
This paper presents a methodology that aims at the incremental representation of areas inside environments in terms of attractive forces. It is proposed a parametric representation…
Left/Right Hand Segmentation in Egocentric Videos
Alejandro Betancourt, Pietro Morerio, Emilia Barakova +3
Wearable cameras allow people to record their daily activities from a user-centered (First Person Vision) perspective. Due to their favorable location, wearable cameras frequently…
Unsupervised Understanding of Location and Illumination Changes in Egocentric Videos
Alejandro Betancourt, Natalia Díaz-Rodríguez, Emilia Barakova +3
Wearable cameras stand out as one of the most promising devices for the upcoming years, and as a consequence, the demand of computer algorithms to automatically understand the vide…
The Evolution of First Person Vision Methods: A Survey
Alejandro Betancourt, Pietro Morerio, Carlo S. Regazzoni +1
The emergence of new wearable technologies such as action cameras and smart-glasses has increased the interest of computer vision scientists in the First Person perspective. Nowada…
