Hi I'm writing the code below and I'm wondering and I'm going to ask! I want to show a new quiver for each loop, but what do I need to change?
for q = 1:2:length(str2num)
a = char(str2num(q))
b = char(str2num(q+1))
imagea = imread(a)
imageb = imread(b)
size(imagea);
size(imageb);
for i=1:(w_xcount)
for j=1:(w_ycount)
max_correlation=0;
test_xmin=xgrid(i)-w_width/2;
test_xmax=xgrid(i)+w_width/2;
test_ymin=ygrid(j)-w_height/2;
test_ymax=ygrid(j)+w_height/2;
x_disp=0;
y_disp=0;
test_ima=imagea(test_xmin:test_xmax,test_ymin:test_ymax);
test_imb=imageb((test_xmin-x_disp_max):(test_xmax+x_disp_max),(test_ymin-y_disp_max):(test_ymax+y_disp_max));
correlation=normxcorr2(test_ima,test_imb);
[xpeak,ypeak]=find(correlation==max(correlation(:)));
%re-scaling
xpeak1=test_xmin+xpeak-wsize(1)/2-x_disp_max;
ypeak1=test_ymin+ypeak-wsize(2)/2-y_disp_max;
dpx(i,j)= xpeak1-xgrid(i);
dpy(i,j)= ypeak1-ygrid(j);
end
quiver(-dpx,dpy)
end
end
