Hi;
I am trying to find the best elliptical fit for irregular shapes in a matrix, say my matrix is defined as:
0 0 0 0 0 0 0 0 0 0 0;
0 0 1 1 1 0 0 0 0 0 0;
0 0 0 1 1 1 1 0 0 0 0;
0 0 0 0 1 1 1 0 0 0 0;
0 0 0 0 0 1 1 1 0 0 0;
0 0 0 0 0 0 0 0 0 0 0;
how can I get the best ellipse fit for this block of ones in the middle of the image? A reference document is much appreciated.
thanks

You know how to find the center of gravity - it's just (in pseudocode)
cogX = sum(x*yourimage)/sum(yourImage)
That gets you the center of gravity in the x direction. That code won't work as is but see if you can translate it into code that does work.
