New Publication in Elsevier Journal Smart Health

Smartphone-based Human Hemoglobin Level Measurement Analyzing Pixel Intensity of a Fingertip Video on Different Color Spaces has been published in the Elsevier Journal Smart Health (Vol 5-6, January 2018, pp. 26-39). In this work by members of the Ubicomp Lab, RGB information of a 10-second fingertip video is used to covert into different color spaces including hue, saturation, value, lightness, and gray. Later, features are extracted from all the combinations of 10 different colors and applied to a Partial Least Squares algorithm. A prediction model is developed with data collected from patients, and achieves a reliable accuracy for detecting hemoglobin level. The article is available here.
