MATLAB_GUI设计-专题讲稿-王正盛

说明：  能够检测图片的特征点，利用DOG算子，实际测试方便，算法清晰，有相关参考文章链接(Be able to detect image feature points)

说明：  logistic混沌映射图，可以得到对logistic混沌映射图和基于logistic对图像加密(Logistic chaotic map)

多媒体技术的EZW图像压缩算法 本算法处理分辩率大于128*128时速度比较慢(multimedia technologies EZW image compression algorithm processing algorithm Resolution of the more than 128* 128 faster than when slower)

（1）熟悉并掌握傅立叶变换 （2）了解傅立叶变换在图像处理中的应用 （3）通过实验了解二维频谱的分布特点 （4）用MATLAB实现傅立叶变换仿真 ((1) be familiar with and master the Fourier transform (2) understand the Fourier transform in image processing applications (3) experiments to understand the characteristics of the two-dimensional distribution of the spectrum (4) simulation using MATLAB Fourier transform)

图形学中的透视投影算法 在屏幕中心绘制立方体的透视投影 可以绘制一点透视图 二点透视图 三点透视图(Graphics in the perspective projection algorithm for drawing a cube in the center of the screen you can draw a little perspective projection perspective two point perspective three-point perspective)

ASIFT算法实现，C++,对有仿射变换的图像匹配更加准确，想比SIFT算子匹配点数多(ASIFT algorithm, C++, affine transformation of the image matching more accurate, want to match more than SIFT operator points)

说明：  用matlab语言实现的图像平滑算法，效果较好，可设置不同的参数得到不同的平滑效果(Matlab language used to achieve the image smoothing algorithm, the effect is better, you can set different parameters of the smoothing effect of different)

在图像边缘点上计算边缘法向量, Compute the norm vector at the boundary(compute the norm vector at the boundary)

利用八方向的sobel边缘检测，实现对图像多梯度的梯度检测，检测出的边缘信息更加平滑连续。(Eight direction Sobel edge detection is used to realize gradient detection of image multi gradient, and the edge information detected is more smooth and continuous.)

说明：  运动检测和背景提取，比较适合于入门者学习，有一定的参考价值(Motion detection and background extraction, suitable for beginners to learn the value of some reference)
