Method For Quantitatively Determining Eyelash Clumping
First Claim
Patent Images
1. A method for quantitatively determining eyelash clumping, the method comprising:
- a. providing an eyelash substrate comprising an array of eyelashes, each eyelash having a length defined by a base and an opposing tip;
b. applying an amount of mascara to the eyelashes;
c. capturing an image of the eyelashes with the mascara applied thereto;
d. analyzing a first portion of the image to obtain first individual thickness measures for each eyelash disposed in the first portion;
e. analyzing a second portion of the image to obtain second individual thickness measures for each eyelash disposed in the second portion;
f. obtaining first average thickness measures from the first individual thickness measures and second average thickness measures from the second individual thickness measures;
g. applying a weighting function to the first and second average thickness measures to generate first and second weighted thickness values; and
h. obtaining a Weighted Average Thickness value from the first and second average thickness measures to provide a quantitative determination of eyelash clumping.
