During the past decades a variety of complexity measures of symbol sequences have been defined.Rapp proposed a taxonomic characterization of such measures based on three defining characteristics:randomness finding versus rule finding,probabilistie versus non-probabilistic and formula based versus model based.These measures can be used to analyze data in the form of one-dimensional time series.However,how to extend the above approaches to characterize two-dirnensional data,such as image is still an open problem.And this problem is important m find some integral morphological parameters which can provide measurement for the quantitative characterization and classification of 2D structures.
