sir i have written this program i want to know that how can i call the function in the loop… clc; clear all; B=imread('bulb.jpg');
A=imresize(B,[128 128]);
[a b]=size(A);
c=8; d=8; l=0;
for i=1:c:a-7 for j=1:d:b-7
C = A((i:i+7) ,( j:j+7)); eval(['out_' num2str(l) '=C']) l=l+1; DCT= dct2(C) quant = [ 16 11 10 16 24 40 51 61; 12 12 14 19 26 58 60 55; 14 13 16 24 40 57 69 56; 14 17 22 29 51 87 80 62; 18 22 37 56 68 109 103 77; 24 35 55 64 81 104 113 92; 49 64 78 87 103 121 120 101; 72 92 95 98 112 100 103 99 ];
quantCoef = round(DCT ./ quant)
endend function output=rle2(Input);
L=length(Input); j=1; k=1; i=1; while i<2*L comp=1; for j=j:L if j==L break end; if Input(j)==Input(j+1) comp=comp+1; else break end; end; Output(k+1)=comp; Output(k)=Input(j); if j==L && Input(j-1)==Input(j) break end; i=i+1; k=k+2; j=j+1; if j==L if mod(L,2)==0 Output(k+1)=1; Output(k)=Input(j); else Output(k+1)=1; Output(k)=Input(j); end; break end; end;
