I have a series of images and we are want to anazlyze their brightness. Basically, how should I proceed with setting a threshold brightness value and then be able to calcalate the % above and below this brightness threshold.

The brighness can be computed as shown here :
If there is a series of images with ordered names (e.g.: img1.png, img2.png, ....) , then you'd need to use [for .. end] loop, e.g.:
Name='img';
Ext = '.png';
for ii=1:n_images
Name_IMG=strcat(Name, num2str(ii), Ext);
AA = imread(Name_IMG);
... % use the commands given in the above link
end
