瓊脂擴(kuò)散技術(shù) - Abstract how to combine color and multiscale information is a fundamental question for computer vision , and quite a few color diffusion techniques have been presented
擴(kuò)散方程方法是圖像處理的基本方法之一，對于圖像的去噪增強(qiáng)邊緣提取等能取得很好的效果。 - 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(shù)用于圖像處理已有了一些研究，但都是研究四元數(shù)傅立葉分析四元數(shù)小波分析或?qū)⒑喕乃脑獢?shù)偏微分方程用于灰度圖像處理，而本文第一次將四元數(shù)擴(kuò)散用于顏色圖像處理，這樣的好處包括： 1可以避免一般非線性擴(kuò)散的階梯效應(yīng)2四元數(shù)擴(kuò)散不需要對圖像導(dǎo)數(shù)進(jìn)行高斯卷積等歸整化操作3更為省時。
