Interpretive Summary: Techniques currently available for small trash measurements in cotton are intrusive and off-line measurements. Advanced Fiber Information System (AFIS) measurements provide the trash distribution in 50 micron increments. Digital camera based and scanner based systems are evaluated for small trash measurements for use in cotton industry. The system measurements are compared to AFIS trash distribution measurements. Real time implementation of these measurements can be used for process control in cotton ginning and spinning industries. This can increase the efficiency of the processes and make the industry more profitable to compete in the global market.

Technical Abstract: This paper discusses the identification of small trash objects in cotton using a machine vision based system; Cotton Trash Identification System (CTIS). Digital camera based (CTIS-Camera) and scanner based (CTIS-Scanner) systems were used to identify objects in target drawings, USDA-AMS Trash Under-Glass boxes, and cotton extracted at three locations in the gin. CTIS-Scanner evaluated scanner resolutions to accurately measure dust size objects. Measurements for trash count and trash area for Trash Under-Glass boxes were compared to High Volume Instrumentation (HVI) measurements. Machine vision results for trash, dust, and total count measurements were compared to Advanced Fiber Information System (AFIS) measurements. CTIS-Scanner first identified an optimum resolution (dpi) for measuring cotton dust. Comparisons were made among CTIS-Camera, CTIS-Scanner, and AFIS measurements. CTIS-Scanner measurements correlate well with HVI measurements on Trash Under-Glass boxes for trash count and percent trash (R2 = 0.9858 and R2 = 0.9932 respectively).
