这是一个医学图像重建程序，用的是滤波反投影算法。-Medical Image Reconstruction using Filtered Back Projection. Matlab code (GUI)+ 4 Sinograms for testing/demonstrations. Can be used as a laboration to compare different numbers of projections, filters and interpolatio

QR码作为一种可高速、全方位识别的二维条码,已经在各行各业中得到了应用,并具有很大发展潜力.本文针对QR码图像的识别过程中可能遇到的图像噪声干扰、QR码占实际拍摄图像的一部分、倾斜、几何失真等问题进行了研究,提出了通过改进型中值滤波去除噪声,使用QR码符号特性定位并对倾斜图像进行旋转,对失真不严重的图像采用控制点变换和双线性插值方法进行几何校正.实验证明, 本文的方法简单有效, 可以用于提高条码的正确识别率.-As a high-speed, full identification of th

偏微分方程在图像处理中的应用代码,有图片及大量代码。-This program implement image interpolation by AMLE method. Firstly, get a number of level sets from an input image by thresholdding. The threshold values are chosen automatically. Then the boundaries for each level set are

The following Matlab project contains the source code and Matlab examples used for use fourier interpolation to increase sampling of an image. also includes an optional filter. . Zero-pads the FFT of an image up to the desired size, then performs IFF
