% This is a GUI for formatting the displacements. This can filter out
% displacements with high correlation coefficient values, convert
% displacements from pixels to real units, and apply very basic corrections
% for lens distortion (although this is generally skipped). The number of
% reference images is equal to the number of current images.
%
% Inputs -----------------------------------------------------------------%
% reference - ncorr_class_img; used for displaying the background image.
% current - ncorr_class_img; used for displaying the background image.
% roi - ncorr_class_roi; ROI WRT the reference image. Note that roi has
% already been reduced.
% plots_u_ref - cell; cell array of u displacement plots WRT the reference
% image. Units are pixels. Note that displacement plots are reduced by
% default.
% plots_v_ref - cell; cell array of v displacement plots WRT the reference
% image. Units are pixels. Note that displacement plots are reduced by
% default.
% plots_corrcoef_ref - cell; cell array of correlation coefficient plots
% WRT the reference image. Note that corrcoef plots are reduced by
% default.
% spacing - integer; spacing parameter
% pos_parent - integer array; this is the position of the parent figure
% which determines where to position this figure
% params_init - cell; params_init{1} is the units/pixel factor, params_init{2} is
% the units, params_init{3} is the correlation coefficient cutoff values,
% and param_init{4} is the lens coefficient if these values have been set
% already
%
% Outputs ----------------------------------------------------------------%
% plots_disp_f - struct; contains the formatted displacement data
% rois_f - ncorr_class_roi; updated ROI for displaying displacements
% within the correlation coefficient range
% pixtounits - double; ratio of units to pixels.
% units - string; name of units
% cutoff_corrcoef - double array; correlation coefficient cutoffs as determined
% by the user
% lenscoef - double; lens coefficient
% outstate - integer; returns either out.cancelled, out.failed, or
% out.success.
