Abstract: A method of measuring blood oxygenation including acquiring one or more images of a portion of a body with an RGB camera, converting RGB colors in the one or more images into a multispectral data imaging cube, wherein the multispectral date imaging cube comprises a red channel, a blue channel, and a green channel, decoupling an oxygenated blood information and a deoxygenated blood information from the multispectral data imaging cube based on a first reflectance of the green channel and a second reflectance of the red channel, and determining a blood measurement based on the oxygenated blood information and the deoxygenated blood information.
