Hi everybody,

Can you please help me to convert binary image results from *_Laplacian of Gaussian (LOG) filter._* to graph?!

I don't know how to perform like such operation;

Thanks A lot.....

Accepted answer

So this is a Laplacian matrix? I suggest you decompose this: L=D-A, where D is the degree matrix and A is the adjacency matrix. Then use gplot, which graphs a adjacency matrix as a set of coordinates in a plane.

"help gplot" is your friend

I Think what you recommend is just brilliant , Really i am very very thankful....but would you please inform me more about how to get that (L)... assume that D is the matrix i got after "Laplacian" filter what is the adjacency matrix??!!

But really (gplot) is just perfect recommendation THANK YOU :)

what i had now is a binary image results from gaussian filter (as attached), do you know how to convert like such matrix to adjacency matrix??!! http://imageshack.us/content_round.php?page=done&l=img163/9633/j1m.png
