A measure of similarities in the feature space should
capture the similarities between the initial image models [5].
Still, many times, the value scale is a subjective measure.
The simple measurement of distances, as the Euclidian
distance, may not maintain the initial similarity. Therefore,
the computation of the right measure of similarity may be
seen as a learning problem. The purpose of learning is to
divide the original feature space into clusters with similar
visual models. A large number of labeled images and the
associated characteristic vectors are used during the last
phase. When a texture model is presented, the network
allocates a class, based on its characteristic vector. The final
ordered set of results is then computed using the Euclidian
distance within the same class [10]. The analysis based on the texture properties is largely
used in multimedia or image databases [1]. Usually, the
images from these databases have very large dimensions,
varying from several MB to hundreds of MB, representing a
serious challenge for the image analysis and data
visualization.
