Edge Linking for curved edges
Hello, I have some big coin Images, which I have processed using Image processing techniques, and I have extracted Edges (curved edges of coins), I am observing some breaks in the edges. So I have to apply Edge linking algorithms for such curved edges. How can I do - I am finding methods like Hough transform, Morpho... 15 May 2010 23:31

ODE OutputFcn
Hi! Could someone please help me? I'm using ode45 OutputFcn with size(t) > 2 to pass some values back to the main routine of my program. The problem is, OutputFcn is not being called at every output step so that the time vector is greater than the my artificial output vector; Does anyone know what may be happenin... 15 May 2010 21:22

How to add legend to an area plot with line plot overlay
Hi, I am trying to create a plot with an area plot and a line plot (on the second axis). My question is how do you add a legend for both plots. Essentially, I want it to look similar to Excel when you just put the second data series on a secondary axis and show the legends together. Ideally I'd like to put the legend i... 16 May 2010 02:43

any tops on evaluating the two simulation outputs and observation?
Hi all, I will like to consult your suggestions about your method/suggestions on evaluation of model performance. A model has been modified based a new modeling scheme. The output from the new modified model is named: output_mod. The output from the original model is named: output_org. There is one observation... 15 May 2010 22:26

Rectangle fitting
Hey all, I need to fit the best rectangle to an object. for my rectangle I can define 5 parameters (x,y,theta,L,W) where (x,y) is the center of the rectangle, theta is the angle of the rectangle and L and W are the Length and Width of the rectangle respectively. I need to optimize an energy function f(). the proble... 15 May 2010 19:10

I want use imcrop as below, thank you for help very much!
get some pics as .fig files I want to use imcrop do such thing like c2 = imcrop(filename.fig,[46 46 10 10]); but the file is the .fig file I mean how could I just get the matrix infomation automatically from the .fig files in the ROI(like the center 100 pixels) because the only file I have is the f... 15 May 2010 20:16
