This study was initiated to provide information and control factors not implemented in current process control technology for gins. The objective is to provide the ginner with knowledge of the presence of bark (or grass) in the ginned lint. An existing color/trash meter was connected to a PC in a laboratory environment. Simple "run length" algorithms were developed which will detect bark 67% of the time when the operator says there is at least one piece of bark in the viewing area. The 5.3 square inch viewing area is considered too small to provide a high probability of containing a piece of bark in lint cleaned cotton during the ginning operation. Work this next year will be directed toward increasing the viewing area of the video trash meter.
