function plot_square_hhmm(ev) % Plot the square shape implicit in the evidence. % ev{i,t} is the value of node i in slice t. % The observed node contains a velocity (delta increment), which is converted % into a position. % The Q2 node specifies which model is used; each segment is color-coded % in the order red, green, blue, black. Q1 = 1; Q2 = 2; Q3 = 3; F3 = 4; F2 = 5; Onode = 6; delta = cell2num(ev(Onode,:)); % delta(:,t) Q2label = cell2num(ev(Q2,:)); T = size(delta, 2); pos = zeros(2,T+1); clf hold on cols = {'r', 'g', 'b', 'k'}; boundary = 0; coli = 1; for t=2:T+1 pos(:,t) = pos(:,t-1) + delta(:,t-1); plot(pos(1,t), pos(2,t), sprintf('%c.', cols{coli})); if t < T boundary = (Q2label(t) ~= Q2label(t-1)); end if boundary coli = coli + 1; coli = mod(coli-1, length(cols)) + 1; end end
