Recent Submissions
-
(Institute of Electrical and Electronics Engineers (IEEE), 2013)Segregating an audio mixture containing multiple simultaneous bird sounds is a challenging task. However, birdsong often contains rapid pitch modulations, and these modulations carry information which may be of use in ...
-
(ACM Association for Computer Machinery, 2019)This paper describes, develops, and validates SciLens, a method to evaluate the quality of scientific news articles. The starting point for our work are structured methodologies that define a series of quality aspects for ...
-
(2016)En sus poco más de doscientos años de historia, el jingju, u ópera de Pekín, ha conseguido el título de tesoro nacional (guocui) y como tal ha asumido la turbulenta historia reciente del país. En la puja por situarse como ...
-
(Bononia University Press, 2006)Expressive performance characterization is traditionally based on the analysis of the main differences between performances, players, playing styles and emotional intentions. This work addresses the characterization of ...
-
(2016)Music in jingju (also known as Peking or Beijing opera) is predefined by tradition. Before the appearance of jingju music composers, actors used to “arrange melodies” (bianqu) for new lyrics according to melodic systems ...
-
(Sound & Music Computing Conference, 2019)This study focuses on the application of different computational methods to carry out a ”modal harmonic analysis” for Jazz improvisation performances by modeling the concept of chord-scales. The Chord-Scale Theory is a ...
-
(2017)We present a study on the behavior of human finger-tapping and the spontaneous expression of rhythm. For the purposes of this study we construe interpret finger-tapping as the casual and rhythmic hitting of objects for ...
-
(2017)In this paper we present an interactive two-dimensional representation of musical chord progressions, integrated into a computer program that generates house music harmonic loops in MIDI format, based on a user’s input. ...
-
(ACM Association for Computer Machinery, 2017)We train and evaluate two machine learning models for predicting fingering in violin performances using motion and EMG sensors integrated in the Myo device. Our aim is twofold: first, provide a fingering recognition model ...
-
(Springer, 2013)We introduce a gradient operator that generalizes the Eu- clidean and Riemannian gradients. This operator acts on sections of vector bundles and is determined by three geometric data: a Rieman- nian metric on the base ...
-
(Springer, 2015)Images captured under adverse weather conditions, such as haze or fog, typically exhibit low contrast and faded colors, which may severely limit the visibility within the scene. Unveiling the image struc- ture under the ...
-
(Springer, 2014)Given any metric that compares images of di erent dynamic range, we propose a method to reduce their distance with respect to this metric. The key idea is to consider the metric as a non local operator. Then, we transform ...
-
(Springer, 2014)We present a method to perform histogram matching be- tween two color images based on the concept of harmonic mapping be- tween Riemannian manifolds. The key idea is to associate the histogram of a color image to a ...
-
(Springer, 2014)In this paper, we provide a new non-local method for image denoising. The key idea we develop is to denoise the components of the image in a well-chosen moving frame instead of the image itself.We prove the relevance ...
-
(Association for the Advancement of Artificial Intelligence (AAAI), 2011)Research in efficient methods for solving infinite-horizon MDPs has so far concentrated primarily on discounted MDPs and the more general stochastic shortest path problems (SSPs). These are MDPs with 1) an optimal value ...
-
(Society of Motion Picture & Television Engineers (SMPTE), 2016)While wide color gamut (WCG) capabilities are a key element of emerging display and projection technologies, at present most image content is recorded using standards such as DCI-P3 for cinema or BT.709 for TV that have a ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2016)We propose a method for the color stabilization of cinema shots coming from different cameras that use unknown logarithmic encoding curves. The log-encoding curves are approximated by a concatenation of gamma-curves, ...
-
(Institute of Electrical and Electronics Engineers (IEEE), 2016)We propose a fast, local denoising method where the Euclidean curvature of the noisy image is approximated in a regularizing manner and a clean image is reconstructed from this smoothed curvature. User preference tests ...
-
(Society of Motion Picture & Television Engineers (SMPTE), 2017)In cinema and TV it is quite usual to have to work with footage coming from several cameras, which show noticeable color differences among them even if they are all the same model. In TV broadcasts, technicians work in ...
-
(Society of Motion Picture & Television Engineers (SMPTE), 2017)Gamut mapping transforms colors of the original (image or video) content to the color palette of the display device with the simultaneous goals of (a) reproducing content accurately while preserving the artistic intent ...
