Digital Image Processing

用comsol做声固耦合的例子，例子的内容是声子晶体的投射系数，对用comsol来计算声子晶体的初学者很不错(Coupled with comsol said anything solid examples, examples of the content is the projection coefficient of phononic crystals, the phonons with comsol to calculate the crystal is very good for beginners)

一种基于DFT的瞬时测频算法，及及插值算法，最后由图形表示测频结果。 (Instantaneous frequency of the DFT-based algorithm, and the interpolation algorithm, by the graphical representation of the frequency measurement results.)

这是一个matlab环境下的关于图像频谱分析的源代码，内附图像。(This is a Matlab environment on the image spectrum analysis of source code, containing images.)

针对图像进行快速傅里叶变换，方便进行频频分析与处理。(Fast Fourier transform for the image, to facilitate frequent analysis and processing.)

方向检测的粒子滤波程序，内含重采样算法。(The direction of the particle filter detection procedures, including re-sampling algorithm.)

基于MAP(最大似然概率）的图像超分辨重建(map-based images super-resolution construction)

共有5个代码其中4个分别实现图像的中值滤波、均值滤波、双边滤波、Lee滤波，另一个是求图像的均值和方差。模板均不固定自己根据需要确定合适的w值。(There are five codes of which four were achieved image median filter, mean filter, bilateral filter, Lee filter, and the other is seeking an image of the mean and variance. Templates are not fixed ourselves w appropriate values as needed.)

压缩感知稀疏恢复中使用的OMP算法，matlab例程(OMP algorithm and MATLAB routine used in compressed sensing sparse recovery)

说明：  对24位的彩色图像用中位切分(中位区分）法将其转换成8位索引图像，并且生成对应的颜色查找表。(median-cut algorithm,8-bit index map, lookup table,256 colors,)

CT（computer tomography ）图像重建算法，FBP，是目前商用CT的主流重建算法(computer tomography reconstruction algrithm)
