Hi guys! how could i detect the object as shown in 1st image? or would it be easier by using 2nd image? It is ok to ignore the small dots/noise, but i wan to detect at least the larger shape. It would be helpful if any keywords is provided for me to learn :)

You may wish to run the morphological close operation to remove holes and connect nearly connected pieces.

Morphological operation are used to fill hole or create hole (you can make gradient too and ....). Do you need this and your image? What are your shapes?
