Graphics PresentationsMandelbrot Set Function,

说明：  matlab程序，用于实现对给定图像做的任意角度旋转(rotate a picture by any angle)

基于PCNN的特征提取,PCNN用于特征提取时，具体平移、旋转、尺度、扭曲等不变性，这正是许多年来基于内容的图像检索系统追求的目标，同时PCNN用于特征提取时，有很好的抗噪性。而且PCNN直接来自于哺乳动物视觉皮层神经的研究，具有提取图像形状，纹理，边缘的属性。用PCNN能很好地对图像进行签名，将二维的图像的特征提取成一维矢量签名。(Feature extraction of specified object is an important preprocessing stage in machine vision systems. In this paper, we present a novel hybrid feature extraction method using PCNN (Pulse Coupled Neural Network) and shape information. First, we use PCNN firing map train to formulate object’s time signature, then we use roundness of each firing map to formulate object’s shape information vector, the final feature matrix we got is combined time signature and roundness. We take correlations as our judge criteria in our experiments. It has been proved that the algorithm is not sensitivity with the rotation, scaling and translation of the object and is a useful method for target recognition applications.)

车道偏离识别的程序，采用的是动态规划算法，对弯道也有比较高的识别率(lane departure algorithm, which has good performance even for curve lane.)

图像检索。通过计算所要检索的图像与图像库中的距离dis，dis最小者与检索图像同类。(image retrieval. Calculated to be indexed images and pictures of the dis the distance, the smallest dis with similar image retrieval.)

完整正确的仿射变换程序，测试过绝对没有错(Complete the correct affine transformation procedures, the test had absolutely nothing wrong with)

M-s中的CV方法( CV)

说明：  用matlab编写的基于内容的图像检索源代码。(Matlab prepared with content-based image retrieval source code.)

基于各向异性扩散的医学图像的边缘检测与分割处理(Based on the anisotropic diffusion of medical image segmentation and edge detection)

实现函数imdilate的膨胀效果，自己编写的matlab函数实现。(Imdilate realize the expansion of function effect, I have written matlab function.)
