clear;clc;
img = imread('cameraman.tif');
y = imresize(img,[256 256]);
imshow(y)
tic
timg = img;
r = 3.62;
x(1) = 0.7;
row = size(img,1);
col = size(img,2);
s = row*col;
%Creation of Logistic function
for n=1:s-1
x(n+1) = r*x(n)*(1-x(n));
end
[so,in] = sort(x);
timg = timg(:);
for m = 1:size(timg,1)
t1 = timg(m);
timg(m)=timg(in(m));
timg(in(m))=t1;
please i want to make a change in this code instead of this 1 D equation "x(n+1) = r*x(n)*(1-x(n));" i want to try this 3D equations :
and how can i write "[so,in] = sort(x);" in the new form after applied this three equations? ?
x(1)=0.2350;
y(1)=0.3500;
z(1)=0.7350;
a(1)=0.0125;
b(1)=0.0157;
l(1)=3.7700;
for i=1:1:70000
x(i+1)=l*x(i)*(1-x(i))+b*y(i)*y(i)*x(i)+a*z(i)*z(i)*z(i);
y(i+1)=l*y(i)*(1-y(i))+b*z(i)*z(i)*y(i)+a*x(i)*x(i)*x(i);
z(i+1)=l*z(i)*(1-z(i))+b*x(i)*x(i)*z(i)+a*y(i)*y(i);
end
x=ceil(mod((x*100000),image_height));
y=ceil(mod((y*100000),image_height));
z=ceil(mod((z*100000),image_height));
please any one help me
