d = xlsread('FaceFour_TRAIN.xlsx');

plot(d);

hold on

idx = find(d>0.04);

scatter(idx, d(idx), pointsize, 'b', '*')

hold off

s = d(1:1,2:end);

fa = movstd(s,20,1);

secarray = movstd(fa,20,1) ;

secidx = find(secarray>.04);

f = secarray(secidx);

[maxvals, maxidx] = maxk(f,10);

sidx = secidx(maxidx);

x = 1:length(s);

plot(x, s, 'b-', sidx, s(sidx), 'go')
