I am going to do a project on underwater Image Processing.My aim is to find Object Identification in Underwater Image. Lot of researches are undergone in underwater Image analysis like species life monitoring,underwater oil/gas pipeline monitoring,underwater building monitoring like Dam structures , water quality,man made objects under sea like crashed flight/ship objects also finding underwater environmental conditional monitoring like earthquake under sea, pollution in sea etc .In that I am having little bit confusion about choosing my target. What is the big scope in underwater Image analysis ?what is the useful and very effective target?Please give me a suggestion.
