I have a idea to solve but I couldn't implement it. The idea is if we can set a particular threshold and only for those threshold only 2 images will be selected using if/else loop. So how to implement it? Please anyone help

What criteria are you selecting these images? Based on name? Or some property of the image?

Where you have the images? In a single folder? If so:

Imgs = dir('*.JPG') ;  % you are in the folder of images 
N = length(Imgs) ;   % Total number of images
idx = []; 
for i = 1:N
    Img = Imgs(i).name ; 
    I = imread(Img) ; 
    % do what you want. May be get threshold value 
    % use if condition for the threshold to save the indices which 
    % obey your criteria
    if threshold_value <= value
        idx = [idx ; i]
    end
end

With the indices idx, pick the images you want.
