Abstract :
The spatial ambiguity among pixels has inherent vagueness rather than randomness, therefore, the conventional methods might not work well. We propose fuzzy homogeneity vectors to handle the greyness and spatial uncertainties among pixels, and to perform multilevel thresholding. The experimental results prove that the proposed approach works better than the histogram-based algorithms
