摘要
在分析一些常见的图像超分辨方法的基础上,根据张量在图像处理中的应用和插值处理的特点,提出了一种基于张量的单幅图像超分辨处理方法,以提高图像的分辨率。通过对标准图像库的图像进行实验表明,该方法能较好地保持原图像中丰富的高频信息,提高图像分辨率,而且图像主观上具有很好的视觉效果,客观上具有较高的信噪比,是超分辨率图像处理中一种行之有效的方法。
On the basis of analyzing some common methods of image super-resolution ,and according to the Tensor in the application of image processing and the features of interpolation processing ,we put forward a kind of Tensor-based super-resolution processing method of Single width image ,so as to improve the resolution ratio of the image .The experimenting of the image of the standard image library indicates that this method can better maintain the rich high-frequency informa-tion of the original image and improve the resolution ratio of the image .Besides ,subjectively ,the image has relatively bet-ter visual effects ,and objectively ,it has relatively higher Signal-to-noise ratio .Therefore ,it is also an effective method to process image of super-resolution .
