image processing

Question

i have got to work on making line follower bot using image processing. my doubt is whether the c code written for that can be contained in on board circuitry ,i.e. with out using a computer. if it is possible then please guide me. the line to be followed is white on green background. so the task. is quite straight forward. i will be highly grateful to you, if you take out a little of your precious time to address my query. thanking you komal prajapati IIT MADRAS
