@Adem Trey & Bo
I have added an updated 'miura_usage.m' script, which should be foolproof now ;)

@Nourul
Miura et al. his paper is not clear about the binarisation method. I have used binarisation based on the median value with good results:
md = median(img(img>0));
BW = img > md;

@Ramana, I have added a demo image and a script to show how to use the function.

@Alan, This is probably caused by the fact that you are using an old version of Matlab. Try replacing the tilde(~) with a dummy variable.

Sir,i want to ask that which are all the features you are extracting from the image

Sir, to perform image rotation can you tell us which main program should call this huang_normalise function?

which filter you use please explain it. I m very thankful to you

Sir,
I got the following error while trying this code. The error is with max_curvature function.Reapeted line tracking is working properly. As am new to matlab i could not troubleshoot the error. Please help me
??? Subscripted assignment dimension mismatch.

Error in ==> miura_max_curvature at 54
k(:,:,1) = (fxx./((1 + fx.^2).^(3/2))).*fvr; % hor

Error in ==> miura_usage at 15
v_max_curvature = miura_max_curvature(img,fvr,sigma);
