(Color online) Pixels of monochrome cameras are sensitive to light covering both visible and near-IR wavelengths. Color cameras have a Bayer matrix of pixels that only allow a certain wavelength range to pass through (namely red, green, and blue) to each pixel. For LSI, we used only the red pixels from the raw Bayer image of the color camera.

(Color online) Single frame excerpt of video taken from simultaneous imaging of a human palm during a reactive hyperemia experiment using both monochrome and color cameras (Media 1). The upper left and upper right images are SFI maps using raw images taken concurrently from a monochrome and a color camera, respectively. The bottom graph is a time trace of the average SFI value of an ROI (bounded by black lines) taken within the palm.
