I divide an image(I) into two subimages (I1 & I2) based on mean value. Now i want to access values of I1 (from 1 to mean value) & I2 (from mean value to last value) to get PDF of image, How to do it?
I = imread('f16.tif');
r=size(I,1);
c=size(I,2);
h1=uint8(zeros(r,c));
h2=uint8(zeros(r,c));
n1=r*c;
n2=r*c;
R=uint8(zeros(r,c));
f1=zeros(256,1);
f2=zeros(256,1);
pdf1=zeros(256,1);
pdf2=zeros(256,1);
cdf1=zeros(256,1);
cdf2=zeros(256,1);
cum1=zeros(256,1);
out1=zeros(256,1);
cum2=zeros(256,1);
out2=zeros(256,1);
Im=mean2(I);
I1=(I(r,c)<=Im);
I2=(I(r,c)>Im);
for i=1:r
for j=1:c
value1=I1(i,j);
f1(value1+1)=f1(value1+1)+1;
pdf1(value1+1)=f1(value1+1)/n1;
end
end
for i=1:r
for j=1:c
value2=I2(i,j);
f2(value2+1)=f2(value2+1)+1;
pdf2(value2+1)=f2(value2+1)/n2;
end
end

Is this?
mean_val=mean2(grayImage);
Image_I1=grayImage(grayImage>mean_val);
Image_I2=grayImage(grayImage<=mean_val);
subplot(211),imhist(Image_I1);
subplot(212),imhist(Image_I2);
Or
Get the PDF of Image_I1 and I2

If you have checked the Histo distribution map, you can get the answer from there also?? Probability distribution map of pixels onthe particular subimage??
Otherwise, can you define the problem again, what do you have and what are you looking for (as a minimal as possible with necessity information)?
