Research Project: New Color Image Analysis Methods to Measure Cotton Color Distributions and Variations (Ci# 12-227)

Location: Cotton Structure and Quality Research

Project Number: 6435-44000-075-13
Project Type: Reimbursable

Start Date: Jan 01, 2013
End Date: Dec 31, 2013

Objective:
To obtain the distribution of color of a cotton sample instead of one single color grade by using image analysis methods, and to investigate if higher variation in cotton color is associated with higher variations in other cotton properties such as maturity and fineness. This research will provide new tools for better evaluation of cotton quality and aid the development of the next generation rapid test instrument for cotton color measurement.

Approach:
Image analysis techniques will be used to explore a series of sub-areas of the area of the measured cotton samples. The size of these sub-areas can be down to pixel level. Sophisticated image processing techniques will be used to analyze the sample images’ color distributions and identify the impacts of trash and other impurities. The digital images can have very high resolutions and color levels that are sufficient for differentiating the variations among the different parts of the sample.
