I'm porcessing a batch of 50 to 800 images in matlab. The progras read some .tif images and then ,after making some changes, outputs an .tif image using imwrite.
The problem is that i want the output image to have a some refence of the scale i'm using. something like a bar of n pixels thats says what is the equivalent in mm(like thos usually used in microscopic measurements), or a couple of axes showing the scale in mm would be even better.
i already know the equivalente of 1 pixel in mm, but i don't know how to showit in every image(keep in mind that there are a lot of images, so it has to be something automatic).
Thanks.
here is the code i'm using right now:
dird=['G:\Alexis\interf camara rapida\Project_2013.08.07_2\W_80_cilindro_4mm\00-50-C2-1D-7E-AB_AutoSave_003_001\00-50-C2-1D-7E-AB_AutoSave_003_001_FR0'];
dirfondo = [dird,'.tif']; % La imagen de fondo debe estar en el mismo lugar que las imagenes a restarselo
fondo = imread(dirfondo);
zonainter=imshow(fondo);
zona=round(ginput(2));
xmin=zona(1,1);
ymin=zona(1,2);
xmax=zona(2,1);
ymax=zona(2,2);
j=0;
for i =1:1:200;
mil=floor(i/1000);
cien=floor((i-mil*1000)/100);
diez=floor((i-mil*1000-cien*100)/10);
uno=(i-mil*1000-cien*100-diez*10);
numero=[num2str(cien),num2str(diez),num2str(uno)];
i; % sin el punto y coma voy viendo por que número va.
j = j + 1 ;
oldfileimage = [dird,numero,'.tif'];
% numerosalida = [num2str(i)];
newfileimage = ['im',numero,'.tif'];
inter = imread(oldfileimage); %Imagen cruda
rango = 255; %// choose the new maximum. (new minimum always at 0.0).
imgMin = double(min(min(inter(xmin:xmax,ymin:ymax))));
imgMax = double(max(max(inter(xmin:xmax,ymin:ymax))));
inter = ((inter - imgMin)*(rango/(imgMax - imgMin)));
imwrite(inter',newfileimage,'tif');
end;
imshow(inter);
