Hi all,
currently I am working on a code for license plate recognition, I have finished coding for license plate extraction,I need help for character segmentation into individual character for some of the connected character inside the car plate.I'm thinking to use FFT2 to improve the edge of the image and then inverse it back using IFFT..is that possible to do this??

You know how wide a character is, I would begin with that knowledge to indiscriminately segment the characters from each other.
- start at left edge, set all values in the column x_length over to black, repeat until edge of that connected component.
- repeat with next CC etc.

No, I don't think that edge enhancement should be necessary. Why do you think it should? I think you need to study on on OCR algorithms first to see how the pros do it: http://iris.usc.edu/Vision-Notes/bibliography/contentschar.html#OCR,%20Document%20Analysis%20and%20Character%20Recognition%20Systems
