hello to all
i have an 4-D dimension Array that contain some RGB picture and i want to set an image that each pixel of it is average of other corresponding pixel in all picture.i wrote below code but doesn't work correctly.
if any one know the correct solution please help me
best regards
if true
clc;
obj=mmreader('street.avi');
Frames = obj.NumberOfFrames;
vidHeight = obj.Height;
vidWidth = obj.Width;
a=read(obj);
im = a(:,:,:,8);
sum = uint16(0);
imframe =(zeros(vidHeight,vidWidth,3));
imframe1=uint16(zeros(vidHeight,vidWidth,3,Frames));
imframe2=uint16(zeros(vidHeight,vidWidth,3));
for p = 1:250
imframe1(:,:,:,p)=(im2uint16(a(:,:,:,p))); %sum = sum + uint16(a(m,n,k,p));
end
for p = 1:250
imframe2=imadd(imframe1(:,:,:,p),imframe2);
end

Replace nearly all your code with
mean(a,4)
You might need
mean(double(a),4)
