摘要
医学图像、遥感图像等图像受到成像设备等因素的限制,一般分辨率较低.为得到高质量的高分辨率图像,提出了对低分辨率图像采用NEDI插值方法提高图像的分辨率,利用高斯滤波器进一步对高分辨率图像去噪的算法.将该算法应用于灰度图像的分辨率提升后,不仅获得了边缘较为清晰的图像,同时有效地抑制了边缘噪声,图像视觉质量较好.
Abstract
Restricted by imaging equipment,human interference and other factors,most images have low resolution.In order to obtain high-quality high-resolution images,an algorithm is given to improve the resolution of images by using NEDI interpolation method for low-resolution images,and further denoising the high-resolution images by using Gaussian filter.After applying the algo-rithm to the resolution improvement of gray scale images,not only the images with clearer edges are obtained,but also the edge noise is effectively suppressed,and the visual quality of the images is better.
