I can't run the code. I don't have the m-file, the fig-file, or the avi file. Why not step through with the debugger and see what lines of code get executed and what the variable values are?

source = videoinput('winvideo',1); thresh = 25; im=getsnapshot(source); %(Remove this) bg = im;
% read in 1st frame as background frame(change this) %
bg = imread('C:\Users\Aatif\Desktop\Thesis\A2.PNG');
bg_bw = rgb2gray(bg);
% convert background to greyscale %fg1 = bg_bw;
% ----------------------- set frame size variables ----------------------- %fr_size = size(bg);
width = size(bg_bw,2); height = size(bg_bw,1); fg = zeros(height, width);
% --------------------- process frames -----------------------------------
for i = 2:100
fr = getsnapshot(source); % read in frame
fr_bw = rgb2gray(fr); % convert frame to grayscale
fr_diff = abs(double(fr_bw) - double(bg_bw)); % cast operands as double to avoid negative overflow
for j=1:width % if fr_diff > thresh pixel in foreground
for k=1:height
if ((fr_diff(k,j) > thresh))
fg(k,j) = 1;
else
fg(k,j) = 0;
end
end
end
%bg_bw = fr_bw;
figure(1),subplot(2,1,1),imshow(fr)
%subplot(3,1,2),imshow(fr_bw)
subplot(2,1,2),imshow(fg)
M(i-1) = im2frame(uint8(fg),gray); % put frames into movie
if ((bg_bw) ~= (fr_bw))
textIn = ('Car has left the parking lot');
ha = actxserver('SAPI.SpVoice');
invoke(ha,'speak',textIn);
h = msgbox('Car has left the parking lot');
% else
%textIn = ('Car is in the parking lot');
% ha = actxserver('SAPI.SpVoice');
%invoke(ha,'speak',textIn);
%h = msgbox('Car is in the the parking lot');
end
end
i can get the if out put
i mean its nt reading the if statement
it just gives the else out put
