How to remove lines as noises from license plate without disturbing the attributes of character and perform vertical projection.

Hello Everyone,

I am newbie here and working on character recognition of license plate. For my initial case I am using a simple image having less amount of distortion or noises. I want to detect peaks of each characters for my further work. I have done some pre-processing methods and here I am attaching two binary images. In 1st there are few lines remaining as noise but the characters appearance is safe while in the 2nd picture these lines are removed but also disturbed the attributes of characters ( I have given explanation in the code for both the pictures)

I need some help so that I can remove all those lines as noises without disturbing the body of every character. Secondly I need suggestions that how can I apply vertical projection on complicated images ( also attached here)

Thanks in advance. Kind Regards.
