Noise detection in smartphone phonocardiogram

Deepan Das, Rohan Banerjee, Anirban Dutta Choudhury, Parijat Deshpande, Nital Shah, Vijay Date +2

ICASSP 2017accepted

This paper presents a demo proposal of a standalone smartphone application that can automatically analyse the signal quality of PCG, as it is recorded on a low-cost smartphone-based digital stethoscope. Features, related to the inherent pattern of the autocorrelated signal envelope, have been used f…

Noise cleaning and Gaussian modeling of smart phone photoplethysmogram to improve blood pressure estimation

Rohan Banerjee, Avik Ghose, Anirban Dutta Choudhury, Aniruddha Sinha, Arpan Pal

ICASSP 2015accepted

Photoplethysmography (PPG) signals, captured using smart phones are generally noisy in nature. Although they have been successfully used to determine heart rate from frequency domain analysis, further indirect markers like blood pressure (BP) require time domain analysis for which the signal needs t…
