Paper Abstract
We propose a new system that makes possible to monitor the evolution of scars after the excision of a tumorous
dermatosis. The hardware part of this system is composed of a new optical innovative probe with which two types of
images can be acquired simultaneously: an anatomic image acquired under a white light and a functional one based on
autofluorescence from the protoporphyrin within the cancer cells. For technical reasons related to the maximum size of
the area covered by the probe, acquired images are too small to cover the whole scar. That is why a sequence of
overlapping images is taken in order to cover the required area.
The main goal of this paper is to describe the creation of two panoramic images (anatomic and functional). Fluorescence
images do not have enough salient information for matching the images; stitching algorithms are applied over each
couple of successive white light images to produce an anatomic panorama of the entire scar. The same transformations
obtained from this step are used to register and stitch the functional images. Several experiments have been implemented
using different stitching algorithms (SIFT, ASIFT and SURF), with various transformation parameters (angles of
rotation, projection, scaling, etc…) and different types of skin images. We present the results of these experiments that
propose the best solution.
Thus, clinician has two panoramic images superimposed and usable for diagnostic support. A collaborative layer is
added to the system to allow sharing panoramas among several practitioners over different places.
