Description
For this problem, handin Matlab .m files for the functions described by the headers below
(also see p. 733 of the text). Note that one of these is a driver which creates inputs for each
function and runs the function on those inputs to obtain the output.
You are also to handin a pdf file (called A4.pdf) reporting on the analysis of the image
00.tif. Extract the part of the image with text, and provide an RMS error comparison as
well as an image difference image of:
1. CS4640 MM boundary vs. bwmorph’s boundary operator
2. CS4640 MM cc vs. bwlabel
3. CS4640 MM convhull vs. bwconvhull
4. CS4640 MM skeleton vs. bwmorph’s skeleton operator
Some notes:
• Indent headers correctly (5 spaces indented lines)
• Do not exceed 72 characters per source line
• CS4640 A5 driver: should show that each function works
None of the functions should write to the interpreter, draw, etc.
