alphabet and number recognition

[amitgangwar_vlsi]

hello sir/madam

i m working on a project that is .......car number plate detection.
In that i have done till character segmentation.
after that i found the individual numbers and alphabets from the image.

but how can i make neural network i don't understand.
i am using matlab 6.5
in that nntool is provided.

in that tool data and network manager window open.

in that window there are a lot of options are there like input, output, input layer, output layer, target etc......

how i have to set these data and network...i did not under stand........
if anyone can help ........
plz help me....

many many thanks in advance

Actually I have answered some of your question in your another thread...

Now, seemed like you have no idea about neural network...If you're not clear about the neural network concepts...please get a book to read...In neural network, there are a lot of different networks which have different purpose respectively.

If you need some guides in neural network, this book is good for beginner:


After you understand about neural network, you can build the neural network using MATLAB built in toolbox or write the code yourself. I only tried to write myself...never use MATLAB nntool before.

If you're interested to write it yourself, maybe this link can help you, there are some sample of neural network code using MATLAB:

thanks for advising..........

yes you are right..neural network is new for me.

i will read the book suggested by you and go through the link given by you........

if i would face some problem i will ask you , if you don't mind.

many thanks for help

Since neural network is still new for you, better you take a look at the book I suggest.

1. Read through all the networks, find out which network is most suitable for your project.
2. Study the algorithm, how the network is working.
3. Write out the code of the network.

I guess you have completed the feature extraction part, as you said you have done until image segmentation.

Then, you can train your network and test it out.

Good Luck...any problem, just post it here, I guess many people willing to help...

 

[amitgangwar_vlsi]

yes i have done till the feature extraction.
i have to detect total 9 characters,i.e. 3 alphabet and 6 numbers.......
i have converted each character in 200 X 1 vector.

now i need the neural network.
i am reading the books and searching on the net.

thanks for guidance

200x1 vector is a bit small, you can test if this is sufficient. If not, then maybe you can make it bigger...anyway, the bigger the vector, training at neural network will take longer time.

You can search online, see most of the people using which network to do this number plate recognition. This is not a new thing. I guess many people have done this kind of project.

Having decide the network, then you can proceed with the neural network training and testing.

Any problem, can post it here.

Can anyone PlZ tell me How to start with image processing..
In my project i need to recognize Arrows (wether it's left,right,up or down arrow). What should i do first? Im good programmer but I dont know much about image processing functions in matlab. Leekk8 or Amitgangwar or any others plz help.

Hi there,

I unable to access the link. Would you mind to state the book title? Any guidance or example to implement NN coding without using Matlab nntool.

TQ

Hi, alabview

Try this, **broken link removed**

I just tried and able to access. Inside there are many matlab code of neural network without using nntool.

The book title should be Neural Networks A Classroom Approach by Satish Kumar.
