运动和散焦模糊图像的复原方法及其应用研究

The Restoration Method of Motion-blurred and Defocus-blurred Images and Its Application

模糊图像复原是从退化的观测图像中重建原始图像的过程,是进行图像处理和模式识别等研究的基础。运动模糊和散焦模糊是两类常见的模糊方式。通过对这两类模糊图像复原过程的研究,分析了模糊图像复原过程中滤波器的选择、点扩散函数的确定以及边缘噪声的处理等关键技术,提出了图像复原的可行方案。计算机仿真试验结果表明,该方法是有效地和可行的。

The purpose of blurred images restoration is that the original image is restructured from the blurred images. The blurred image restoration is the base technology for images processing and pattern recognition. The motion-blurred and defocus-blurred are two kinds of blurred styles. The effectual approach is presented by the research of filter, spread function and edge noise in the blurred images restoration processing. The computer restoration experiments on actual blurred images show that the method is effective and practical.
