Texture-based recognition for image segmentation and
classification is very important in many domains and different
numerical features coming from a variety of approaches have been
proposed. Texture segmentation using six features based on the
fractal dimension has been used elsewhere. This paper studies
properties of these features from the point of view of
dimensionality reduction, mutual relation, differential relevance,
discrete quantization, and classification ability. In an
experimental framework, a set of statistical, soft computing, data
mining and machine learning methods were used on a set of
different textures (Pearson's correlation, rough sets, principal
components, and inductive classification). It was found that
fractal features effectively have texture recognition ability.
Some of these are very relevant (the fractal dimension of smoothed
versions of the original image and the multi-fractal dimension).
Not so many quantization levels of fractal dimension variables are
required in order to achieve high recognition performance. This
novel methodology can be used in another type of databases to know
its more relevant attributes and be able to simplify models. |
