Image resolution enhancement algorithm based on NEDI interpolation
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.
