Application of Computer Image Processing in Feather Down Color Grader

A feather down color grader based on computer image processing technology was presented to carry out the work of feather down color grading automatically. The image segmentation, windows processing, the calculation of the color fluff area and its barycenter were introduced. The selection of the optimal threshold and the generation of bit control signal were also discussed. The experimental results showed that the performance of the fluff color grader was reliable.
