function presteps_to_compute_motion(I1Match,I2Match,t,tmpdir)
%% Description
% Compute motion with a brigthness constancy data term defined on (I1,I2)
% and a feature matching similarity term defined on (I1Match,I2Match). The
% feature matches are computed by the DeepMatching method [Revaud et al. 2016], with the
% source code provided by the authors
% For more details see the paper: "Imaging neural activity in the ventral
% nerve cord of behaving adult Drosophila", bioRxiv

% Hierarchical Deformable Dense Matching. Int J Comput Vis 120:300–323
%% Input
% I1,I2: Images used for the brightness constancy term
% I1Match,I2Match: Images used by the feature matching similarity term
% fnDeepMatching: filename of the deepmatching code
% param: parameters of the algorithm (see 'default_parameters.m')
% t: number of the frame in the image sequence
