HOG

说明：  1.使用medfilt2函数对‘lena.bmp’进行不同模板大小的中值滤波，并观察效果 2.使用fspecial函数构造‘gaussian’, ‘sobel’, ‘prewitt’, ‘laplacian’, ‘average’等不同滤波算子，使用filter2函数对‘cameraman.tif ’进行滤波，观察不同滤波器的效果 3.设计频域理想低通和理想高通滤波器，对‘phantom.bmp’图像进行频域滤波，显示滤波结果。然后改变截止频率，观察对结果的影响。 4.对‘homo.bmp’进行同态滤波，其中频域同态滤波器自行设计。要求在程序注释中说明你设计该滤波器的思想。(1' lena.bmp 'The median filtering with different template sizes was carried out and the effect was observed2. Fsspecial function is used to construct different filter operators such as' Gaussian ',' Sobel ',' Prewitt ',' Laplacian ',' average ', etc' cameraman.tif 'Filter and observe the effect of different filters3. Design ideal low pass and ideal high pass filters in frequency domain' phantom.bmp 'The image is filtered in frequency domain and the filtering result is displayed. Then change the cut-off frequency and observe the effect on the results.4. Yes' homo.bmp 'The homomorphic filter is designed by ourselves. The idea of designing the filter should be explained in the program notes.)

画任意旋转点源码，例程程序使用画板，根据两点的坐标及旋转角度画出旋转点的坐标。(Videos arbitrary rotation point source , a routine procedure using Sketchpad , coordinate rotation point to draw the coordinates of two points and the angle of rotation .)

说明：  MATLAB计算石墨烯能带，判断最近邻，对角化哈密顿量(Calculation of graphene energy band by MATLAB)

这个是最成熟的人脸检测算法viola-jones的matlab版本实现，适合搞研究的同学们(a matlab implementation of the viola-jones face dection!)

Impulse response, system response, for signal processing

3、 请采用学过的图像复原算法（鼓励自己研究新算法），对 blur3.jpg、 sadhna_53_45.bmp和telescope.bmp 图像进行复原处理。(3, please use the learned image restoration algorithm (to encourage their study new algorithm), to blur3.jpg, sadhna_53_45.bmp and telescope.bmp image restoration processing.)

基于FFT的配准程序，用在图像配准中的粗匹配中，对噪声、图像中物体发生运动等极为鲁棒！ (FFT-based registration procedure, used in image registration in the coarse matching, noise, motion and other image objects occur very robust!)

说明：  基于retinex算法对图像进行去雾算法(Image defogging algorithm based on retex algorithm)
