| 摘 要： | 主要研究对已损坏了的图像恢复.它是利用退化现象的某种先验知识(退化模型),按退化的逆过程重建图像的技术.其退化模型是原始图像经过算子,或系统经退化因素作用之后和噪声叠加,形成退化后的图像,即实际得到的图像.利用逆滤波法复原的原理,通过已知复原图像和噪声,采用退化函数,经过反傅里叶变换,求出原始图象.同时以Visual C++6.0与Matlab为开发工具.实验表明本算法具有良好的性能,能有效抑制和清除干扰对测试结果的影响,具有算法简单可靠等优点,使图像质量得到改善.

| Abstract: | This paper mainly studies the restoration of damaged images.It is a technique which uses some kind of prior knowledge of degradation phenomena to reconstruct images according to the inverse process of degradation.Its degradation model is the original image processed by operator,or system factors,and it is superimposed with noise to form degradation of the image,namely,the actual image.Using the inverse filtering method,through the recovery of known images and noise,using the degradation of function,and afte... |
