Read the introductory sections in the
MATLAB user guide regarding file I/O and displays. Familiarise
yourself with the MATLAB "HELP" facility.
We have prepared some short macro files which can
be used for basic image display and region based histogramming which
you should download and save as MATLAB .m files.
Down load the images from this page as ".pgm" files and load them into MATLAB as arrays.
Practice drawing regions of interest and understanding the resulting data in the histogram.
Finally, using the histogramming routine as a starting point, attempt to write your own MATLAB routine which allows you to plot the grey levels along a selected line. You will need to be able to use this method in later practicals as an investigative tool.
