Motion Magnification Algorithms for Video-Based Breathing Monitoring

no code implementations29 Nov 2022 Veronica Mattioli, Davide Alinovi, Gianluigi Ferrari, Francesco Pisani, Riccardo Raheli

In this paper, we present two video processing techniques for contact-less estimation of the Respiratory Rate (RR) of framed subjects.

Maximum Likelihood Speed Estimation of Moving Objects in Video Signals

no code implementations10 Mar 2020 Veronica Mattioli, Davide Alinovi, Riccardo Raheli

The proposed method is composed of a sequence of pre-processing operations, that aim to reduce or neglect perspetival effects affecting the objects of interest, followed by the estimation phase based on the Maximum Likelihood (ML) principle, where the speed of the foreground objects is estimated.

Markov Chain Modeling and Simulation of Breathing Patterns

no code implementations5 Oct 2016 Davide Alinovi, Gian-Luigi Ferrari, Francesco Pisani, Riccardo Raheli

The presented CTMC statistical model can be strategic to describe realistic breathing patterns and devise simulators useful to develop and test novel and effective video processing-based monitoring systems.
