RLE Algorithm Based Image Data Coding Method of Tujia Brocade Double Knitting Pattern

In order to ensure the resolution of Tujia brocade double-sided woven pattern image and reduce the image storage space, a data encoding method of Tujia brocade double-sided woven pattern image based on RLE algorithm is proposed. A double-sided braided pattern image data encoder is designed as the executive component of the encoding method. Through filtering, image enhancement, illumination compensation and other steps, the pre-processing of pattern image is realized. Using the image data transformation of RLE algorithm, the image data coding of Tujia brocade double-sided woven patterns is realized. Through the performance test experiment, it is concluded that compared with the traditional coding method, the peak signal-to-noise ratio of the optimized design method is improved by about 5.7 db, the image compression ratio is improved by about 0.22, and the image data coding efficiency is significantly improved.
