Hello,
my task is to create a graph showing how a set a of images change in relation to the reference image. For defining the difference I am using the Structural Similarity (SSIM) index. Now my problem is that my loop does not go through all image in the folder directory but only takes the first one. In order to make the graph I need to assign to each image the value of the SSIM index (ssimval) and plot it.
It would be very helpful if someone could show me what I am doing wrong in my code. Thank you!
Here is my code so far:
reference_img = imread('rock01b_noback.png'); %read reference img folder = 'C:\Users\...'; morphimages = dir(fullfile(folder,'*.png')); %specify pattern of files in folder for i = 1:length(morphimages) imagename = morphimages(i).name; fullimagename = fullfile(folder,imagename); fprintf(1, 'Reading %s.\n', fullimagename); imagearray = imread(fullimagename); [ssimval,ssimmap] = ssim(imagearray,reference_img) %find ssim index for each img in folder end
