How do I import an .AVI movie into 3d matrix in MATLAB

I am trying to write a function that imports an .AVI file and returns a 3D matrix in MATLAB.

Ultimately, this is so I can perform an fftn on the 3d matrix.

Solution

  • Blockquote

    % this is basically for gray scale video

    function video3d

    carobj=mmreader('carwide.avi');
    % the carwide.avi is video considered for making it % matrix

    nFrames=carobj.NumberOfFrames;

    M=carobj.Height; % no of rows

    N=carobj.Width; % no of columns

    video=zeros(M,N,nFrames,'uint8'); % creating a video 3d matrix

    for k= 1 : nFrames

    im= read(carobj,k);

im=im(:,:,1);           % all three layers will have same image

video(:,:,k)=im;

    end

    end
