Resumen
The improvement of the technology in many areas of the knowledge, in particular on the acquisition of images and videos, led to the necessity for index and retrieve such contents from a huge set of files. Nowadays, this task has been gaining more attention from both the academic community and corporate. The image retrieval based on its content is a strategy that reduces the limitation in creating tags or labels to describe its contents, whicha is based on image feature extraction. In the biological area has a great necessity for methods of image retrieval. In particular, in Brazil it is necessary to catalog the flora in order to preserve the knowledge about each species available. The correct cataloging will help the researches, agronomists and biologists to preserve and retrieve information quickly and accurately. In this context, it is proposed the development of an open-source software with the following features: to extract texture image features by using Haralick’s descriptors and Histogram Variation Quantified; to perform the analysis of some different classification methods applied in the leaf recovery of various species; and to analyze the impact of feature selection methods in the computational time for learning and classification. The obtained results show that the selected features can be used for annotation, given that in most classifiers was possible to obtain better results than 70%. As a conclusion, it was developed an open source software tool, jImageFeature, freely available at <http://code.google-.com/p/jimagefeature/ >.
