Character Recognition for License Plate Recognition Sysytem

HELLO. i have completed the process of character segmentation for my project License Plate Recognition System. I am having difficulty regarding character recognition. Kindly help accordingly. My program till char segmentation is written below. The figure im working on is: http://tinyurl.com/cl7arkp

PROGRAM:

imagen=imread('D:\images working\b.jpg');

figure(1)

imshow(imagen);

title('INPUT IMAGE WITH NOISE')

%%Convert to gray scale

if size(imagen,3)==3 % RGB image

      imagen=rgb2gray(imagen);

end

%%Convert to binary image

threshold = graythresh(imagen);

imagen =~im2bw(imagen,threshold);

%%Remove all object containing fewer than 30 pixels

imagen = bwareaopen(imagen,30);

pause(1)

%%Show image binary image

figure(2)

imshow(~imagen);

title('INPUT IMAGE WITHOUT NOISE')

%%Label connected components

[L Ne]=bwlabel(imagen);

%%Measure properties of image regions

propied=regionprops(L,'BoundingBox');

hold on

%%Plot Bounding Box

for n=1:size(propied,1)

      rectangle('Position',propied(n).BoundingBox,'EdgeColor','g','LineWidth',2)

end

hold off

pause (1)

%%Objects extraction

figure

for n=1:Ne

      [r,c] = find(L==n);

      n1=imagen(min(r):max(r),min(c):max(c));

      imshow(~n1);    

      figure

      pause(0.5)

end

Thank You very much for sharing this code

[Kevin]

I tried this on my own photos and it extracts even non letters and non-numbers, how can I fix this?

how can we print in text without ocr?

Hello there are many topics on OCR. I use CORR2 built-in function, to process OCR, ANN is better. I red your code... Smart! You grabbed the right approach, but not complete. You need to work on a hundred image snapshots sample to find out many kinds of problem you can face regarding vehicles picture capture. Front, Back, Noise, illumination, Motion blur, background, etc...

Hi Puneet,

I am working on number plate identification code. I think I saw your video on YouTube recently. Good to know you finally implemented it successfully. Is there any possibility that you may provide me with the code. I am really stuck with the bounding box step.

Thanks.
