When Segmentation is Not Enough: Rectifying Visual-Volume Discordance Through Multisensor Depth-Refined Semantic Segmentation for Food Intake Tracking in Long-Term Care

no code implementations24 Oct 2019 Kaylen J. Pfisterer, Robert Amelard, Audrey G. Chung, Braeden Syrnyk, Alexander MacLean, Heather H Keller, Alexander Wong

We propose a novel deep convolutional encoder-decoder food network with depth-refinement (EDFN-D) using an RGB-D camera for quantifying a plate's remaining food volume relative to reference portions in whole and modified texture foods.

Food for thought: Ethical considerations of user trust in computer vision

no code implementations29 May 2019 Kaylen J. Pfisterer, Jennifer Boger, Alexander Wong

In computer vision research, especially when novel applications of tools are developed, ethical implications around user perceptions of trust in the underlying technology should be considered and supported.

Towards computer vision powered color-nutrient assessment of pureed food

no code implementations1 May 2019 Kaylen J. Pfisterer, Robert Amelard, Braeden Syrnyk, Alexander Wong

With one in four individuals afflicted with malnutrition, computer vision may provide a way of introducing a new level of automation in the nutrition field to reliably monitor food and nutrient intake.

Non-contact hemodynamic imaging reveals the jugular venous pulse waveform

no code implementations15 Apr 2016 Robert Amelard, Richard L Hughson, Danielle K Greaves, Kaylen J. Pfisterer, Jason Leung, David A. Clausi, Alexander Wong

Here, we demonstrate for the first time that the JVP can be consistently observed in a non-contact manner using a novel light-based photoplethysmographic imaging system, coded hemodynamic imaging (CHI).

Non-contact transmittance photoplethysmographic imaging (PPGI) for long-distance cardiovascular monitoring

no code implementations23 Mar 2015 Robert Amelard, Christian Scharfenberger, Farnoud Kazemzadeh, Kaylen J. Pfisterer, Bill S. Lin, Alexander Wong, David A. Clausi

The results support the hypothesis that long-distance heart rate monitoring is feasible using transmittance PPGI, allowing for new possibilities of monitoring cardiovascular function in a non-contact manner.
