    If I understand your post correctly, its called Optical Character Recongnition (OCR for short). It's not trivial, as a quick web search on the topic would suggest.

    You'd better choose more specific task. "Image detection" is an umbrella term for a bunch of problems and algorithms. Even with recognition of license plate you have several tasks:
    - determine if license plate is presented on the picture and find its position, rotation;
    - rotate and rectify it (the simplest part);
    - split the fragment into character cells (by clustering or more naive methods);
    - for each cell you'll be able to apply some not very complex OCR algorithm since license plates usually use very similar fonts - so it would be like measuring presence of black pixels in several control points and choosing the closest character.

    Generally, detect or recognize image from camera will need OCR technology. And If you wanna to process the detected image, it requires the OCR solution be qualified with post-processing functions.
