An Improved Air Tissue Boundary Segmentation Technique for Real Time Magnetic Resonance Imaging Video Using Segnet

C. A. Valliappan, Avinash Kumar, Renuka Mannem, Girija Ramesan Karthik, Prasanta Kumar Ghosh

ICASSP 2019accepted

This paper presents an improved methodology for the segmentation of the Air-Tissue boundaries (ATBs) in the upper airway of the human vocal tract using Real-Time Magnetic Resonance Imaging (rtMRI) videos. Semantic segmentation is deployed in the proposed approach using a Deep learning architecture c…

Binaural Speech Source Localization Using Template Matching of Interaural Time Difference Patterns

Girija Ramesan Karthik, Prasanta Kumar Ghosh

ICASSP 2018accepted

In this paper we present a template based algorithm for localizing speech sources from a binaural recording. Binaural recordings are associated with head related transfer functions (HRTFs) for each direction which are specific to the object, say head, in between the two microphones. So, using these…
