Categorizing Cotton Trash Shapes Using Video Imagery

M.A. Lieberman and Z.Y. Zhao


 
ABSTRACT

Definitions of trash categories in ginned cotton should be made and the amount of trash in each category should be measured. The purpose was to produce an indicator for ease of cleaning the bale of cotton. Information about these measurements should be presented in a manner that would aid the cotton industry in preparing new cotton grading standards. Classer cotton samples were evaluated with the methods reported at the 1989 and 1990 Cotton Quality Measurements Conferences. Recognition of different non-lint (trash) material was too complex for this initial analysis. Simpler parts of the experiment were then evaluated. Results of these elementary tests are reported. Experiments evaluated: 1) the consistency and accuracy of measuring each piece of trash, 2) the system's ability to recognize trash across images, and 3) the system's power to classify a new trash data set. Ninety-two of ninety-six pieces of trash were correctly identified in the test data set. Possible causes for the incorrectly identified trash are discussed.
