%%%% convention:

%%%%% parameters %%%%%%%%


%%%%%%%%%%%%%%%%% step 1: rough segmentation %%%%%%%%%%%%%%%%%%%%
%%% perform segmentation at each frame
%%% by conventional method
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


%%%%%%%%%%%%%%% step 2: contour initialization %%%%%%%%%%%%%%%%%%
%%% intialize contours in the first frame
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


%%%%%%%%%%%%%%% step 3: main loop (propagation) %%%%%%%%%%%%%%%%%
%%% propagate cell contours from frame K-1 to frame K
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%


%%%%% step 3.1: conduct matching between frame {K, K+1, ..., K+Kt}


%%%%% step 3.2: build matching force map MF


%%%%% step 3.3: contours evolution


%%%%% step 3.4: initialize contours for newly entered cells


%%%%% step 3.5: update information and prepare for next iteration
