In Computer-Aided Diagnosis-based schemes in mammography analysis each module is interconnected, which directly affects the system operation as a whole. The identification of mammograms with and without masses is highly needed to reduce the false positive rates regarding the automatic selection of regions of interest for further image segmentation. This study aims to evaluate the performance of three techniques in classifying regions of interest as containing masses or without masses (without clinical findings), as well as the main contribution of this work is to introduce the Optimum-Path Forest (OPF) classifier in this context, which has never been done so far. Thus, we have compared OPF against with two sorts of neural networks in a private dataset composed by 120 images: Radial Basis Function and Multilayer Perceptron (MLP). Texture features have been used for such purpose, and the experiments have demonstrated that MLP networks have been slightly better than OPF, but the former is much faster, which can be a suitable tool for real-time recognition systems.

This academic work has as its objective to demonstrate the fundamental role of communication as a tool towards implantating an environmental management project in organizations, aswell as familiarizing with the complex relashionship be-tween green businesses and its publics. The concern involving environmental prob-lems are increasing and it directly affects the consumer’s choice and their requests on organizations’ behavior. The integration with all sectors of economy is necessary as a part of a developing process that has as its main objective the environmental conservation and therefore the quality of human life on planet. There is also the question of how in the process of communication there is not an only way of interven-tion, but a continuous reciprocal action. The work is accomplished with an analyses of the green management communication of the business Grupo Abril
