this is my code
clc; clear all; close all;
im=imread('images.jpg');
size(im);
fid=fopen('document.txt','r');
c = fread(fid, 'uint8=>char')';
bin=dec2bin(c);
a=size(bin,1)*size(bin,2);
b=1
delta=20
wi=bin(3)
f=im(3,3)
m=floor(f/((2^b)*delta))
r=f-(2^b)*m*delta
f1=(2^b)*m*delta+wi*delta+r/(2^b)
in execution
b =
1
delta =
20
wi =
1
f =
7
m =
0
r =
7
f1 =
255
the value of f1 should be 24
I think the problem is in saving wi=bin(3) value in matlab because when I put wi=1; manually in my code it gives me 24 but my main code involves a loop and every time wi will take a new value from bin table
why is f1=255??
thank you
