چکیده

In this paper, we present a new segmentation method for range images consisting of a set of planar cross-sectional contours. Our approach is novel in that it uses fuzzy criteria for grouping primitives and identifying homogeneous regions. We have tried our method with images provided by a structured light sensor. In this case, the image sequence corresponds to the scene profiles obtained with the successive positions of a rotating plane of laser light. We assume that the object surfaces can be modelled by a set of quadratic patches. The primitives used for region segmentation result from the approximation of the light profile by second order curves. An efficient tracking of these noisy curves is achieved by using a fuzzy decision-making algorithm. Region growing is then performed by our method by matching 2D curves from the image sequence. We present results obtained with real scenes consisting of multiple objects of arbitrary shapes. They show that an efficient surface segmentation may be obtained with fewconstrained environments including planar or curved shapes.

On fuzzy rule-based algorithms for image segmentation using gray-level histogram analysis

One of the biggest problems in computer vision systems, analyzing images having high uncertainty/vagueness degree, is the treatment of such uncertainty. This problem is even clearest in the segmentation process. Fuzzy set theory and fuzzy logic are ideally suited for dealing with such uncertainty. This work extends our earlier and on-going work in automated image labeled segmentation, modeled f...
