SUBDIVIDE AND CONQUER Active Contours and Surfaces for Biomedical Image Segmentation
Anaïs Laure Marie-Thérèse Badoual
Ongoing advances in imaging techniques create new demands regarding the analysis of images in medicine and biology. Image segmentation is a key step of many image analysis pipelines and its proper execution is a particularly challenging task. This thesis i ...
EPFL2019Binary Sparse Coding of Convolutive Mixtures for Sound Localization and Separation via Spatialization
Hervé Bourlard, Volkan Cevher, Afsaneh Asaei, Mohammadjavad Taghizadeh, Saeid Haghighatshoar
We propose a sparse coding approach to address the problem of source-sensor localization and speech reconstruction. This approach relies on designing a dictionary of spatialized signals by projecting the microphone array recordings into the array manifolds ...
Institute of Electrical and Electronics Engineers2016Computational Methods for Underdetermined Convolutive Speech Localization and Separation via Model-based Sparse Component Analysis
Hervé Bourlard, Volkan Cevher, Afsaneh Asaei, Mohammadjavad Taghizadeh
In this paper, the problem of speech source localization and separation from recordings of convolutive underdetermined mixtures is studied. The problem is cast as recovering the spatio-spectral speech information embedded in a microphone array compressed m ...
Elsevier Science Bv2016Pyramic array: An FPGA based platform for multi-channel audio acquisition
Microphone arrays techniques present compelling applications for robotic applications. Those techniques can allow robots to listen to their environment and infer clues from it. Such features might enable capabilities such as natural interaction with humans ...
2016Enabling Speech Applications using Ad Hoc Microphone Arrays
Microphone arrays are central players in hands-free speech interface applications. The main duty of a microphone array is capturing distant-talking speech with high quality. A microphone array can acquire the desired speech signals selectively by leading t ...
EPFL2015Hardware and Algorithms for Ultrasonic Depth Imaging
Depth imaging is commonly based on light. For example, LIDAR and Kinect use infrared light, while stereo cameras use visible light. These systems require hardware operating at high sampling frequencies, precise calibration, and they dissipate significant p ...
Ieee2014How to Localize Ten Microphones in One Fingersnap
Martin Vetterli, Ivan Dokmanic
A compelling method to calibrate the positions of microphones in an array is with sources at unknown locations. Remarkably, it is possible to reconstruct the locations of both the sources and the receivers, if their number is larger than some prescribed mi ...
IEEE2014Perception and Reproduction of Auditory Spatial Impression
As audio reproduction systems evolve to incorporate many loudspeakers, the potential to evoke faithful auditory spatial impressions increases. Psychoacoustic principles of auditory spatial perception, and methods for production and reproduction of acoustic ...
