I just want to extract the number plate region..how can use the human vision toolbox for that??

i thought of extracting the portion by the hough transformation results i got..any way is there a way to do that by cropping??

thanks in advance

dude :
My job doesn't involve license plate extraction from complicated scenes so I don't have any code for you, and any guess I made on how to do it would probably not be the latest and greatest method. But here's where you can find all those methods (new, old, great, not so great):

http://iris.usc.edu/Vision-Notes/bibliography/contents.html

Drill down to this section:
16.7.2.5 License Plate Recognition, Extraction, Analysis
Here you will find a citation of every paper ever published on the subject.
Time for you to do some research.
Good luck with it.

Hey thank you very much for your post Image Analyst..but i found a way to extract only the number plate region after hough transformation results. cheers..

using this code,

[code]


[Ilabel num] = bwlabel(BWoutline);

Iprops = regionprops(Ilabel);
Ibox = [Iprops.BoundingBox];
Ibox = reshape(Ibox,[4, num]);

subplot(2,1,1); imshow(im);

%% Plot the Object Location
hold on;


%% try

for cnt = 1:num
lig= rectangle('position',Ibox(:,cnt),'edgecolor','g');
disp('this is :');disp(cnt);disp(Ibox(:,cnt));


cur= imcrop(im,Ibox(:,cnt));
subplot(2,1,2); imshow(cur);
pause(0.5);

end
[/code]

us is having a little fun at your expense. He extracted the number by
looking at the image and reading it off.

But I've got to say -- what is it about license plate number recognition
that makes it such a common assignment in image processing courses (which I
assume is the reason you're working on this task)? Is it that it's just
challenging enough but not too challenging a problem for students to do as
part of a course?

ah us made me confusing by telling that..cuz i have never heard about it,
hmmm yeah before i start this project i ddnt know that this is soo commonly for students projects. but after researching i got to know. but its a challenging one for me. cuz no one taught me matlab and im self studying it.

even the little steps im finding to implement this project gives me a lot of happiness.
in the coleg we are normaly using vb.net,java,C++ and etc normal languages. but i thought to switch to a different language and experience it. so thats how i came up with this idea.
