Abstract: This paper presents an image segmentation method imitating human focusing visual attention in image interpretation using possibilistic knowledge modeling concepts. The proposed pixel level method consists on the Iterative Possibilistic Knowledge Diffusion (IPKD) on immediate neighbourhood pixels. The advantage of this mechanism is to provide iterative diffusion of per-pixel certain knowledge to surrounding pixels in order to progressively refine the segmentation process. The diffusion process is achieved using image smoothing techniques such as Nagao and Gabor filtering, mean filtering and anisotropic diffusion. Those diffusion techniques are then compared in the possibilistic knowledge representation space. The merit of a possibilistic knowledge representation, rather than a grey-level sensor based representation, is demonstrated by both experimental and synthetic data. Producing the lowest error rates, possibilistic knowledge diffusion using Nagao filter is adopted for the approach assessment. Experimental results using synthetic images as well as mammographic images from MIAS (Mammographic Image Analysis Society) data-base, are performed in order to assess the efficiency of the proposed segmentation method according to the visual criterion as well as some quantitative criteria. IPKD's performance (in terms of recognition rate, 94.37% and global predictive rate, 92.18%) is compared with three relevant reference methods: level-set, Fuzzy C-Mean and region growing methods. The IPKD approach outperforms the other three methods, respectively, at the recognition rates of 89.77%, 84.43% and 88.11% and at the global predictive rates of 87.86%, 89.72% and 84.04%. Noise-sensitivity experiments have been conducted on synthetic as well as on real images. The proposed IPKD approach outperforms the three reference methods and in addition, exhibits a desired stability behaviour. [ABSTRACT FROM AUTHOR]
