Rayleigh-fudu

This code demomstrates an improved algorithm based on the local binary fitting (LBF) model in Chunming Li et al s paper: "Minimization of Region-Scalable Fitting Energy for Image Segmentation", IEEE Trans. Image Processing, vol. 17 (10), pp.1940-1949, 2008. Usage: These codes can be used for Matlab 7.0.4 or higher versions in Windows. Run the Demos in the M-files for several test images. Once an image comes out, click the mouse to generate a polygon as the initial contour: left click to get a number of points, then right click to get the end point. The number of iterations may need to be increased if the initial contour is too far away from the desired object boundary.

FDTD仿真，空气和玻璃界面的折射现象，可以观察到电磁波的折射现象。(A source of electric field is defined at the top edge of the spatial domain,(in glass) on the left half, which is a hard sinusoidal source, in that it does not change its value due to interference from external fields i.e in other words,the source is a perfect electric conductor. )
