Hands Off: A Handshake Interaction Detection and Localization Model for COVID-19 Threat Control

no code implementations18 Oct 2021 A. S. Jameel Hassan, Suren Sritharan, Gihan Jayatilaka, Roshan I. Godaliyadda, Parakrama B. Ekanayake, Vijitha Herath, Janaka B. Ekanayake

The proposed model is the first dyadic interaction localizer in a multi-person setting, which enables it to be used in public spaces to identify handshake interactions and thereby identify and mitigate COVID-19 transmission.

A generalized forecasting solution to enable future insights of COVID-19 at sub-national level resolutions

no code implementations21 Aug 2021 Umar Marikkar, Harshana Weligampola, Rumali Perera, Jameel Hassan, Suren Sritharan, Gihan Jayatilaka, Roshan Godaliyadda, Vijitha Herath, Parakrama Ekanayake, Janaka Ekanayake, Anuruddhika Rathnayake, Samath Dharmaratne

In this study, a forecasting solution is proposed, to predict daily new cases of COVID-19 in regions small enough where containment measures could be locally implemented, by targeting three main shortcomings that exist in literature; the unreliability of existing data caused by inconsistent testing patterns in smaller regions, weak deploy-ability of forecasting models towards predicting cases in previously unseen regions, and model training biases caused by the imbalanced nature of data in COVID-19 epi-curves.

DeepLight: Robust & Unobtrusive Real-time Screen-Camera Communication for Real-World Displays

no code implementations11 May 2021 Vu Tran, Gihan Jayatilaka, Ashwin Ashok, Archan Misra

We show that a fully functional DeepLight system is able to robustly achieve high decoding accuracy (frame error rate < 0. 2) and moderately-high data goodput (>=0. 95Kbps) using a human-held smartphone camera, even over larger screen-camera distances (approx =2m).
