On-line measuring for unusual-fine in raw cotton based on image-recognition technology with MATLAB

The different fine online detection system of raw cotton based on image-recognition technology with MATLAB is described. The software and hardware structure of the online measuring system are discussed, and the principle of the system initial, pretreatment, image-characteristic collection and differentiates are analysed. It has proved that, using this system, the discerning rate can be more than 99%, thus can reduce worker's labor intensity and improve production efficiency.
