Remove noise in such a situation is not simple. I suggest you create a model from objects.You can use deep neural network for detection of objects regions.Then according to the output of dnn do probe segmentation by gallery pair sample.

2016-11-01 09:43:58 -0500 marked best answer How to use Mat.at<Internal type>(i,j)?

How can I use element in Mat by at function without specifying its type.

sample:

Mat.at(i,j) == if (Mat.type == CV_8U) --> Mat.at<unsigned char>(i,j)

Mat.at(i,j) == if (Mat.type == CV_32F) --> Mat.at<float>(i,j)
