  5. In addition to showing the solution to linear qd and its analysis, one form of nonlinear qd is discussed. compared with other color diffusion techniques, considering the interactions between channel pairs, qd has the following advantages : 1 staircasing effect is avoided ; 2 as diffusion tensor, the image derivative is regularized without requiring additional convolution ; 3 less time is needed. experimental results demonstrate the effectiveness of linear and nonlinear qd applied to natural color images for denoising by both visual and quantitative evaluations

    雖然講四元數用於圖像處理已有了一些研究，但都是研究四元數傅立葉分析四元數小波分析或將簡化的四元數偏微分方程用於灰度圖像處理，而本文第一次將四元數擴散用於顏色圖像處理，這樣的好處包括： 1可以避免一般非線性擴散的階梯效應2四元數擴散不需要對圖像導數進行高斯卷積等歸整化操作3更為省時。
