With Smartphone Camera, Researchers Can Create Hyperspectral Images to Analyze Skin Changes

Via University of Washington | April 1, 2020

Modern smartphone cameras can be harnessed to analyze and track skin changes and blood flow dynamics under the skin, report UW Bioengineering Professor Ruikang Wang and his graduate student Qinghua He, in the February issue of Biomedical Optics Express. Dr. Wang, who is also a professor of ophthalmology, and He developed a smartphone-based system that produces images comparable to those created by expensive hyperspectral imaging tools in clinical laboratories. The tool could be useful to dermatologists and others in evaluating skin changes, including doing mole checks and spotting potential cancers. Wang and He say the system, which uses an unmodified smartphone, is easy to operate, very cost-effective, and could make hyperspectral analysis available to healthcare providers in rural and low-resource settings.

The research was recently highlighted in an article in Physics World magazine Feb. 18.

The imaging system uses the smartphone’s built-in RGB camera and flashlight. The team’s system then applies the Wiener estimation method to transform the images into “pseudo”-hyperspectral images with 16 wavebands, covering a visible range from 470-620 nanometers. The processing method uses weighted subtractions between wavebands to get information about how much light is absorbed due to colorful proteins and molecules in skin, mainly hemoglobin and melanin… Continue reading.
