slanted
surface for the patients to place their foot. The design ensures
consistent illumination and a fixed optical path length between
the sole of the foot and the camera, so that pictures captured at
different times would be taken from the same camera angles and
under the same lighting conditions. Task 2) was implemented
by utilizing an accurate, yet computationally efficient algorithm,
i.e., the mean-shift algorithm, for wound boundary determination,
followed by color segmentation within the wound area for
assessing healing status.
