Extraction of blood absorption information content from snapshot hyperspectral image. (a) The raw images directly exported from the spectral band 10 in the camera, from three volunteers (marked as 1, 2, and 3, respectively). (b) Corresponding images showing blood absorption information content derived from the weighted subtraction between band 6 (556 nm) and 9 (625 nm), (c) Overlaid images of raw images and corresponding blood absorption images. (d) Corresponding images derived from weighted subtractions between band11(529 nm) and 10(603 nm). (e) Corresponding images derived from weighted subtractions between band 6 (556 nm) and 8 (615 nm). (f) Contrast enhancements of the blood absorption information content by summing the images showing in (b), (d) and (e). 1,2,3 represent three different cases in the blood extraction. Red arrow: pimples or light red spots, black arrow: melanocytic nevi.
