I dont know what is wrong the result are not good it find maybe 10% of plates. Algoritm is based on vertical and horizontal histogram, quality of picture is realy good and plate is almost at center of picture.
Maybe the problem is in edge detection? is" A=edge(A,'roberts');" enough or i need to use somthing else, or the problem is smowhere else?
this is a sample how plate looks http://www.naklejka.robego.drl.pl/galerie/t/tablice-rejestracyjne_269.jpg is quite simple.
can somebody help me solve this problem? i dont need to find 100% of the plates by 10% is just bad;/ what is wrong???
