Your first step should be identifying where the license plate is in the image. First collect a lot of license plate number images with different variations amongst themselves i.e. different angles, different lightning, different background etc. Now you know what dimensions the license plates are in malaysia and try to find that dimensions in your image, now within that domain (license plate region) try different algorithms i.e. extracting edges and seeing if edges conform to any alphabets etc.

[Sean de Wolski]

The dimensions of the license plate will change if the picture was taken from 500ft away or taken from 1ft away...

Well yes that is why i was suggesting senstivity analysis on a varying number of images, but i did not use correct language and also effectively i was sending him on a wild goose chase. Sorry Matt. And it looks like Jason pointed to a more relevant database.
