1. CD contents

• README
• Images (image directory)
• Spectra (skin spectral reflectance directory)
• CameraRGB (directory of camera response curves)
• IllumSPD (directory of illuminant spectral power distribution (SPD))
• Table (text file of rough categories for faces (gender, glasses, skin group))

2. Technical details

A. Images

• Picture Format - BMP compressed
• Size - 428x569 24-bit
• Camera used - 3CCD SONY DXC-755P
• Illuminants used -A (Planckian 2856K), H (Planckian 2300K), TL84 (F11) and D65 (Daylight 6500K)
• Imaging condition - dark room with gray background
• File Naming - RCXXX.bmp.Z

 where R = reference illuminant for camera white balancing and
 C = current illuminant. R,C  = [h,a,t,d]
 XXX = [1..111] person number

  for cases when person has glasses on - RClXXX.bmp.Z

B. Spectral Information

• File format - Text, first column is wavelength
• Range - From 400 to 700 nm in 10 nm steps

i. Skin spectra

• Measuring Device - Minolta CM 2002 spectrophotometer
• File Naming - personXXX_N where XXX=[1..111], N = [1..3] (measurement locations)

Note : Spectral power distribution of the lamps and the camera spectral response were not measured in the laboratory.

ii. RGB Spectral Sensitivities  (derived from manufacturer)

• File Naming - Sony_R, Sony_G, Sony_B

iii. SPD of Illuminants

• File Naming - T (TL84 fluorescent SPD derived from manufacturer)

          A,D,H - (computed SPD's of Incandescent A, Daylight and Horizon illuminant respectively)
