% uploading my image I=imread('washington.jpg') % converting it to binary II=rgb2gray(I); figure();imshow(II) BW=bwlabel(II,8);
% This commands choose connected components bigger than a threshold and show them in different images % but I want this CCs to be ommited from the main image and I don`t want to assign a threshold mannually for k=1:max(max(BW)) out=(BW==k); [i,j]=find(out~=0); if length(i)>500 figure();imshow(out2) end end

Use bwareaopen() or propfilt() or bwareafilt().
