Note 1: Since these are binary files, a MATLAB script (called ShowMulticamRGB) is provided for visualizing the images.

Note 2: Use the white and black standards at the corner of each image to compute the reflectance spectrum of each pixel in the image. Setting the average black standard somewhere near 0 (e.g., 10) and the average white standard somewhere below 255 (e.g., 225) to avoid negative number and saturation, respectively.
