摘要图像的超分辨率重建技术就是利用一组低质量的、低分辨率图像(或运动序列)来产生单幅高质量的、高分辨率图像。图像超分辨率重建技术的应用领域极其宽广。在医学,军事,公共安全,计算机视觉等领域都存在着重要的应用前景。图像超分辨率重建技术可以提高图像的识别精度和识别能力。图像超分辨率重建技术可以实现目标物的专注分析,从而来获取感兴趣区域的更高空间分辨率的图像,而不必直接采用数据量巨大的高空间分辨率图像的配置。在数字图像被广泛应用的领域,高分辨率就意味着拥有更多的细节信息,可以更好的进行观察、识别。目前的超分辨率重建技术有三类:基于插值的方法,基于重建的方法,基于学习的方法。本文的研究工作如下:

Title :  Research on super resolution reconstruction algorithm of traffic bayonet image            
Abstract
Super resolution image reconstruction technology uses a set of low quality, low resolution image (or sequence of motion) to produce a single high resolution and high quality image. Super resolution image reconstruction is used in many fields including military, medicine, public security, computer vision etc.. Super resolution image reconstruction technique can improve the recognition ability and the accuracy of image. Super resolution image reconstruction technology can realize the analysis object of attention, so it can get the region of interest (ROI) is a high spatial resolution image, and it is unnecessary to apply large amounts of data with high spatial resolution image configuration. In the field of digital image application, high resolution means with more detailed information, which is good for observation and identification. Super resolution reconstruction currently has three categories: interpolation based method, reconstruction based method, and learning based method. The research work of this paper is as follows:

We understand and master the simple interpolation algorithm at first in this dissertation:neighbor interpolation bilinear interpolation, bicubic interpolation. Understanding the reconstruction method based on a learning approach, this kind of method employs all the information available in the input image sequence, without any additional prior knowledge. As learning based approach, SR algorithm is a combination of the traditional multi frame reconstruction method and the learning based algorithm frame. In the case of only one image in a higher magnification it still has a better reconstruction effect.
Keywords:Super resolution reconstruction; structural similarity; interpolation algorithm; scale invariance;
