lsb embedding for invisible image watermarking

绘制极坐标图函数，绘制多条时，是将参数组成行向量(Draw polar plot function to draw multiple parameters composed of row vectors)

plz give the matlabcode

MATLAB实用源代码 1.图像反转 MATLAB程序实现如下： I=imread( xian.bmp ) J=double(I) J=-J+(256-1) 图像反转线性变换 H=uint8(J) subplot(1,2,1),imshow(I) subplot(1,2,2),imshow(H) (matlab code)

代码是matlab编写，有例图，可直接运行（注意修改路径）。主要用来检测桥面、路面裂纹，有详细函数功能说明和算法思想，实现了路面规则条纹背景的频率估计，采用频域滤波可有效去除路面图像接近估计频率的噪声，保留目标裂纹，实现了初步的检测功能，但是功能还不完善，可作Demo供大家参考。有兴趣的朋友可以逐步完善、移植，有兴趣的朋友请与我联系。(Matlab code is written, there is case diagram, can be run directly (Note to modify the path). Mainly used to detect bridge, road cracks, a detailed description and algorithms Function thinking to achieve a frequency of road rules striped background estimation, using frequency domain filtering can effectively remove the image close to estimate the frequency of road noise, keep cracking goal to achieve a preliminary detection function, but the function is not perfect, can be used for Demo for your reference. Interested friends can gradually improve, transplant, friends who are interested, please contact me.)
