Abstract:
The digital image is analyzed to determine the captured target color (12) and the captured colors of the test card color fields (20). A correction model accounting for ambient lighting conditions and distortion due to image capturing device is computed from the captured and known colors of the test card color fields. The correction model is applied to the captured target color (60) and the estimated true target color is compared to a database of true product color (80) to determine a nearest matching.
Abstract:
Methods and systems for measuring with a Color Measurement System of predetermined specification and evaluating the color of skin, teeth, hair and material substances with a Color Index. The principles of this invention also relate to techniques for using such a Color Measurement System with the Color Index in medical applications such as the detection of chromogenic disease including bilirubin infant jaundice, cosmetics applications and in the evaluation of the color of hair or teeth, and other applications. The Color Index is measured and calculated from the reflectance spectrum of any skin (or teeth, hair or material substance) by a two step process. The first step is the weighting of the visible spectra with a unique set of weighting factors which calculate a sample's reflectance spectrum's contribution to the appearance of four color components independent of the illuminating condition. The second step places the sample's reflectance spectrum's contribution to the appearance of the four color components in opponency to each other and calculates the Color Index providing attributes representative of correlates of lightness-darkness (L, also referred to as lightness), redness-greenness (M) and yellowness-blueness (N).
