Abstract: Color reduction technique is crucial for many applications,such as segmentation and presentation of color images.Based on color components operation and bit-mask reduction of grey value,the paper presented a novel image processing technique which was applied to obtaining textile image.The coefficient of color components operation and the mode of linear combination were determined by experiments.This research has shown that color components operation can enhance the visualability of patterns of the fabric,and bit-mask operation can reduce noises in its grey image and ensures real-time processing.
