摘要 图像的空间分辨率是评价图像质量的一个关键性指标,也是图像应用中举足轻重的一个参数。然而在图像获取的过程中,诸多因素均会导致图像质量的下降或退化。解决这一问题的一种有效办法就是超分辨率图像重建技术,介绍了超分辨率图像重建技术,对其两种主要的方法进行了分析,给出了凸集投影算法的步骤并通过实验数据进行了图像重建的验证。 The spatial resolution of the image is a critical index of the image quality and also an important parameter in the area of the image application. However there are many factors lowering and degenerating the quality of the images in the process of the image capture. Here the super-resolution image reconstruction and two central methods are introduced and the image reconstruction based on the POCS is verified through an experiment.
