How can Matlab make a title for all figures, according to the "imread" input image.

I'm doing image processing on images, and a lot of figures are plotted. I am reading in one image at a time in, perform some functions and then have outputs. I want the result figure to show a title that will show what image I was working on, before looping to a next image.

Leernaam has .png images for instance diaretdb1_image002.png

Thus: imageIN = imread(LeerNaam);

image processing .... result=bw.*I;

figure, imshow(result), ... title ' I want it to display diaretdb1_image002 automatically, because imageIN used it and all processing was done on imageIN'

Use sprintf() to create a string that you can use for a title, for example:

caption = sprintf('Working on %s\nImage #%d out of %d',...
  filename, currentImageNumber, totalNumberOfImages);

If you want the title to appear above just the current axes, then you can use title():

title(caption, 'FontSize', 24);

otherwise, you can use set() to send the caption to a static text label control:

set(handles.text1, 'String', caption);
