Hi,I'm working on a task to detect blue ball in sea with opencv. How can i detect it without overlapping with sea or sky color ? Should i use bit-wise operations ?

In a case when you can't use color detection, the next step is to try texture segmentation (Haralick, Gabor filters, wavelets, structure tensors...).

The blue ball and blue sky are not the same, because of colour ranges. You will have to two ranges one for ball and one for sky

using blob detection you can easily detect blue color in blue background. take reference from here :- https://www.learnopencv.com/blob-dete...
