ImageAnalyst:

edges must be find automaticly. these pictures are CT scans 
of a bone with drilled holes. images from 'the beginning' 
and from 'the end' of hole aren't so bad, they do not have 
so many cracks and i've got an algorithm that find edges in 
them.

problem starts with images from 'the middle' of the bone - 
they have a lot of cracks. i tried some filter but as i 
posted before nothing helps.
i put few more pictures: http://test-bone.pl.tl/

what do You think of them?


Vihang Patil:

shame to say but i do not know how :| as i look at  matlab 
help it is written for example:
I  = imread('circuit.tif');
       rotI = imrotate(I,33,'crop');
       BW = edge(rotI,'canny');
       [H,T,R] = hough(BW);

so at first i need to 'edge' image.. 
but maybe i should read it more carefuly
