Examples
- Perona - malik equation extracts image feature direction based on gradient method , which can be very erroneous
Perona ? malik方程对图像特征方向的提取是基于梯度方法的。基于梯度提取图像特征方向的方法很容易产生错误。 - 2 ) processing image by using perona - malik equation evolves image to partly planar image . this is the main reason causing blocky effects
2 ) perona ? malik方程处理图像，是将图像向分块水平图像过渡，这是产生块效应的主要原因。 - Perona and malik ' s work on anisotropic diffusion has been one of the most influential papers in the area . they proposed to replace gaussian smoothing by a directional diffusion that preserves edges
基于偏微分方程的图像平滑技术研究领域中以perona和malik在系数各向异性分布方面的研究最有影响。 - 3 ) evolves perona - malik equation to the form of weighted smoothing in two orthogonal directions . brings hessian method , which is an approach to extract the image feature direction , into the technology of smoothing image
3 )推导perona ? malik方程为在相互垂直方向不同程度平滑的形式，将提木于柿微分方程的图街个滑技术及其应用研穴摘要取图像特征方向的hessain方法应用到图像平滑技术中。 - Their work opened a number of theoretical and practical questions in the pde image processing fields . after consulting many references we make the following research : 1 ) analysing perona - malik equation by taking it into the framework of robust 3 estimation
本论文在研究参考众多文献基础上对该项技术及应用做了以下研究工作： 1 )将perona ? malik方程转化到统计鲁棒性估计理论框架下进行了研究。
