细菌觅食算法与粒子群优化算法相结合的程序，可以实现适应度函数的最值计算，有很好的参考价值。(Bacterial Foraging algorithm and particle swarm optimization combined program, you can achieve the best fitness function value, and have a good reference value.)

该程序是对原图像进行梯度加掩模的三次分水岭分割(That the procedure was in the original image mask plus three gradient watershed segmentation)

图像DCT变换水印提取 图像DCT变换水印提取(DCT image watermark images extracted from DCT watermark image watermark extraction DCT)

说明：  对图像中不同的颜色进行提取，从而实现图像分割和不同颜色处理(Extracting different colors from images)

双边滤波，在平滑噪声图像的同时又可保留图像的边缘信息(Bilateral filtering, the noise in the image while smoothing the image edge information can be retained)

小波分解，db4小波分解，分解为4层，可以直接运行(Wavelet decomposition, db4 wavelet decomposition, decomposition level of three layers, can be directly run)

用于轴承球与滚道之间，模拟生成非高斯随机粗擦表面(Analog generate non-Gaussian random rough surfaces rub)

医学图像分割和偏移场矫正方法的matlab代码(the matlab code for medical image segmentation and bias correction)

包括harris经典算法、harris-Laplace算法，以及susan算法，鲁棒性好(Harris, including the classic algorithm, harris-Laplace algorithm, as well as susan algorithm, better robustness)

使用sift+RANSAC完成两幅图像的特征提取和匹配，并将较小图像区域在另一幅中用方框圈出来。运行plot.m。(This code uses sift and RANSAC to extract features of two images and then finds and marks the smaller image in the other image.run plot.m)
