摘要

We are working in collaboration with geographers to study, a set of pebbles digital images. Among the features geographers want to get automatically, pebble sides number is intuitively defined as shown in Fig 1. It is merely computed after a thick polygonalisation of pebble contour We propose an incremental and linear algorithm, free of restrictive hypothesis, which relies on previous works of Debled et al. [3, 4, 5]. We give some results on synthetical and real images.
