Dear Abhilash,

although it would be possible to build a microarray image analysis 
application from the tools provided in the EBImage package, it seems 
that most likely it would be an unwise investment of your time. There 
are many well-tested applications out there for just this task, see e.g. 
here for an overview:


and I am sure a bit of Googling will bring you more.

Best wishes
