Character Recognition for License Plate Recognition Sysytem
Afficher commentaires plus anciens
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

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

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.
