diffusion technique meaning in English

扩散工艺
扩散技术

Agar diffusion technique
琼脂扩散技术
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
扩散方程方法是图像处理的基本方法之一，对于图像的去噪增强边缘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
虽然讲四元数用于图像处理已有了一些研究，但都是研究四元数傅立叶分析四元数小波分析或将简化的四元数偏微分方程用于灰度图像处理，而本文第一次将四元数扩散用于颜色图像处理，这样的好处包括： 1可以避免一般非线性扩散的阶梯效应2四元数扩散不需要对图像导数进行高斯卷积等归整化操作3更为省时。
