This is really basic stuff. If you want a tutorial of other basic stuff you'll need to do image processing, see my image segmentation tutorial "BlobsDemo": http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 It does basic blob detection and measurement.

With imread?
im = imread(filename);
The folder containing output.bmp has to be on the MATLAB path.

Vinayak, it's good practice to use exist and fullfile
fullFileName = fullfile(folder, 'output.bmp');
if exist(fullFileName, 'file')
% File exists, read it in.
imageArray = imread(fullFileName);
else
% Not there - alert the user.
warningMessage = sprintf('Image file not found:\n%s', fullFileName);
uiwait(warndlg(warningMessage));
imageArray = []; % Create a null array (avoids certain other errors).
end
folder obviously holds a string that is the folder name where your image file lives.
