Algorithm of Clustering for Color Images Segmentation

The problem of recognition of objects inside an image can be divided in two steps: segmentation phase and classification of the objects. The cluster is a representative method of the segmentation techniques that divides the pixels in different groups, based on properties of coherence and similarity. We propose a variation of the implementation of the cluster method based on density, OPTICS, which it considers creation of clusters and the density of the points and it develops a classification with regard to their parameters. In this method, we choose color attribute as an important element to define a cluster; the color space considered is the HVC. The experiments were carried out with images that consider different situations, in most cases the results are close to what we expected, once a cluster is found the classification process can be done.
