hii,i have to compress images to reduce their resolution so that the time of processing will be reduce. i have a code for compression for one image only but i have to compress the all frames of my folder. so please give the way to do this. So that i can read all the frames of the folder and silmultaneously can compress them and save them in an another folder. I am giving the code for single image compression below :-
close all;
image = imread('person200.jpeg');
input_image_used = im2double(image);
n=input('Enter the decomposition level : ');
[Lo_D,Hi_D,Lo_R,Hi_R] = wfilters('haar');
disp('The decomposition vector output is');
disp('Size : ');
[thr,nkeep] = wdcbm2(c,s,1.5,3*prod(s(1,:)));
[xd,cxd,sxd,perf0,perfl2] = wdencmp('lvd',c,s,'haar',n,thr,'s');
disp('Compression ratio in percentage : ');
title('Input image');
title('Compressed image');
Please help me if anyone can, your help is much awaited and will be appreciated. thank you in advance.
