It is the same requirement, and the same discussion. We are working through it with the person there.

% Images Folder Directory
% Call the images one by one, there are multiple simmilar question, please check
% Load any one image and get the size
imgae_data=rgb2gray(imread(image_file)); %Considering Gray Image
%To select six pixels can be done in two ways
%One approach using randi function
% 2nd Approach using pixelinfo
% Now call the 25 images one by one
for i=1:25
%Read 1st images
% Get the 6 pixels values using x,y
image_data=image1; %when i=1
% Get the pixel form the image at x,y
pix_data{i,1}= % array with 6 pixels value
Once done, pix_data is a cell array with 25 elements and individual cell elements having 6 pixels value
See pix_data details
>> whos pix_data
Name Size Bytes Class Attributes
pix_data 25x6 1200 double
Next plot the pix_data with individual column wise, you will get 6 curves.
