In this paper we propose a new contour descriptor for reconstructing fish otolith contours that uses half the number of coefficients needed by the classical elliptical Fourier descriptors (EFDs) for the same accuracy. The ...

This paper analyzes applications of cumulant analysis in speech processing. The main focus is made on an integral representation for cUl1luJants using integrals involving cyclic products of kernels. These integrals serve ...

Abstract. Wavelet derived codification techniques are widespread used in image codifiers. The wavelet based compression methods are adequate for representing transients. In this paper we explore the use of the discrete ...

This paper focuses on an experimental feature selection for the images of otoliths in order to validate their effectiveness in a multiclass classifier used to resolve an automatic otolith identification process. Otoliths ...

In this paper the authors propose a new closed contour descriptor that could be seen as a Feature Extractor of closed contours based on the Discrete Hartley Transform (DHT), its main characteristic is that uses only half ...

Abstract. Monitoring and tracking of elderly people using vision algorithms is an strategy gaining relevance to detect anomalous and potentially dangerous situations and react immediately. In general vision algorithms ...

Les úlceres són una causa important de morbiditat i mortalitat a tot el món i es produeixen per diverses causes, com ara diabetis mellitus, neuropatia perifèrica, immobilitat, pressió, arteriosclerosi, infeccions i/o ...

Compendi d’estudis publicats entre el 2017 i el 2019, que demostren, entre d’altres coses, que els professionals sanitaris d’atenció primària de la salut (APS) utilitzen habitualment les aplicacions per a telèfons intel·ligents ...

Abstract. In this paper we show how a nonlinear preprocessing of speech signal -with high noise- based on morphological filters improves the performance of robust algorithms for pitch tracking (RAPT). This result happens ...

Scoring animal behavior is increasingly needed for better understanding ecological processes. For example, behavior shapes harvesting likelihood, thus management of harvested resources should improve after accounting for ...
