what properties? When you read an image you will get RGB matrix, which would be huge to store.

在 MATLAB Online 中打开

clc; clear all ;
F = dir('*.jpg');   % your images extension and you are in the present directory of images
nimage = length(F) ; % length of images
E = zeros(nimage,1) ; % initiliaze energy 
M = zeros(nimage,1) ; % intiilize mean 
% loop for each image 
for ii = 1:nimage
   I = imread(F(ii).name);   % read image 
   % do what you want, let Ei, Mi be calculated energy and mean
   % E(ii) = Ei ;
   % M(ii) = Mi ;
end
