info=aviinfo('viptraffic_original.avi');

k=info.NumFrames;

Hello Srikanth,

To calculate the average frame, you need to convert each frame to a numerical array, sum them up, and then divide by the total number of frames. Here's how you can modify your code to compute the average frame:

video = VideoReader('viptraffic_original.avi');

% Initialize a matrix to store the sum of all frames
sumFrames = zeros(video.Height, video.Width, 3, 'double');

% Loop through each frame to compute the sum
while hasFrame(video)
    frame = im2double(readFrame(video));
    sumFrames = sumFrames + frame;
end

% Compute the average frame
averageFrame = sumFrames / video.NumFrames;

% Display the average frame
imshow(averageFrame);
title('Average Frame');
