Read the introductory sections in the
MATLAB user guide regarding file I/O and displays. Familiarise
yourself with the MATLAB "HELP" facility.
Run the matlab "demos" and select the "edge detection"
demo from the
"Image Processing" toolbox.
Try out the various edge detectors on the images provided and try to asses their relative performance on the basis of noise, connectivity and completeness of identified edges. Is there a method which performs best on all or most of the images?
Now try manually adjusting the edge threshold. Is it possible to improve
upon the initial detection results with a manually selected threshold?
