This project is a simple implementation of the Iterative Back-Projection (IBP) algorithm for solving the Super-Resolution problem. It was first proposed by Michal Irani in her 1991 paper "Improving resolution by image registration". The imag

通过对投影数据进行滤波反投影从而得到图像的FBP算法，设置的滤波器可以自行更改为其他的-Through the projection data is filtered back-projection algorithm to obtain an image of the FBP, the filter settings can be changed to other self-

反像投影，可以调节图像，进行任意角度的转换，得到全新的视觉效果。-Back projection, you can adjust the image, arbitrary angle conversion to give new visual effects.

二维图像的投影和图像重建，直接傅里叶反变换法，先反投影后滤波，先滤波后反投影，卷积反投影(Two dimensional image projection and image reconstruction, direct Fourier inverse method, first backprojection, after filtering, first filter, back projection, convolution back projection)
