The sound is part of the human stimuli, whose information is given by pressure fluctuations into the ear. The perceived sound quality has recently evaluated the performance of audio coders. Newer evaluation methodologies involve psychological and physiological responses of human listeners. However, there is no available methodology providing any relationship between the perceptual assessment and the...
Quality assessment is a technique used for evaluation of processes monitored by multimedia sources (Audio, Image, Video). Perceptual measures has been recently proposed for quality assessment of those sources. This work illustrates the correlation analysis of the Image Quality Assessment (IQA) required to evaluate a specific coding process. For this purpose, we create a database of images processed...
Current object detection systems reach high detection rates, at the expense of requiring a large training database. This paper presents a new method for object detection, that gives state-of-the-art results, while using a reduced training database. The proposed system relies on a new local feature extraction approach inspired by Convolutional Neural Networks, Principal Component Analysis and Multilayer...
This paper presents FLOSSMetrics, a European Commission 6th Framework Programme- funded research project. The main objective of FLOSSMETRICS is to construct, publish and analyse a large scale database with information and metrics about libre software development coming from several thousands of software projects, using existing methodologies, and tools already developed. The project also provides...
Current object detection systems provide good results, at the expense of requiring a large training database. This paper presents an unsupervised iterative object detection system using a selection of previously detected objects in order to perform new object detection. Our experiments show that this method enables face detection with a greatly reduced set of examples and outperforms the detection...
From the input text, the linguistic-prosodic module obtains the phonetic transcription and prosodic marks that reflect both the syntactic structure and some rhythmical constraints. The synthesis module is a variation of the MBE (multiband excitation) vocoder with an LPC (linear predictive coding) filter that is very flexible for prosodic modifications. From a parametrized acoustic database, the algorithm...
