滤波图像 meaning in Chinese
filtered image
Examples
- Adaptive weighted median fiter for image denoising
自适应加权中值滤波图像去噪算法 - Multiple wavelet bases wiener filtering in image denoising
基于多小波基维纳滤波图像去噪 - Summarize the common image pre - processing methods and point out their merits and faults . discuss the boundary effect of gaussian low - pass filtering ( glpf ) . to improve it , the zero - order gaussian filtering for an open profile ( gfo ) is used
讨论了高斯低通滤波的边界效应,利用零阶开环高斯滤波算法,对高斯低通滤波进行了改进,使滤波图像在图像大小不改变的情况下,边缘处的滤波效果得到明显的改善。 - An approach for quality assessment of the filtered images was proposed . after qualitative and quantitative assessment , some conclusions have been drawn : ( 1 ) spatial filters are affected greatly by filtering window size , the size of 5 5 presents best result ; ( 2 ) enhanced frost filter , enhanced lee filter and gamma - map filter smooth the speckle noise well with a small sacrifice of losing texture details and narrow edges , which are better than other popular spatial filters ; ( 3 ) the results show that the proposed filter retains texture and edges well , so more researches are expected
通过对jers - 1sar图像的各种滤波图像进行了目视评价和指标比较，得出如下结论: ( 1 )各种空间滤波器受滤波窗口的影响很大， 5 5大小的滤波窗口滤波效果较好； ( 2 )对比各种常用的空间滤波器，增强的frost滤波器、增强的lee滤波器和gamma - map滤波器在去噪和纹理、结构特征保持方面效果最好； ( 3 )小波滤波方法在保持sar图像纹理细节方面表现出了很好的优势，还有待进一步研究。 - In the thesis , the knowledge and principle on magnetic particle testing , digital image and image restoration are introduced first . according to demand of the system , the wiener filter restoration based on parameter identification is proposed and analyzed by the matlab experiment , the specification of evaluating effect of image restoration is presented according to out - of - focus radius as well . programming by visual c + + 6 . 0 , jpeg image files are decoded and converted into bmp files , colorful image is converted into gray image and out - of - focus micro - crack image is restored
本文首先介绍了磁粉探伤、数字图像及图像复原的相关知识和基本原理；根据自动磁粉探伤系统应用的要求，给出了一种基于参数辨识wiener滤波图像复原方法，并进行matlab实验分析，提出一种基于散焦半径的复原效果的评判标准；采用vc + + 6 . 0编程，实现jpeg解码并转换成bmp文件格式，然后变换为灰度图像，再对散焦微裂纹图像进行复原处理。
