1. Explorando informações texturais das visões crânio-caudal e médio-lateral oblíqua para extração e classificação Fuzzy de imagens mamográficas / Explorando informações texturais das visões crânio-caudal e médio-lateral oblíqua para extração e classificação Fuzzy de imagens mamográficas
The computerized system to support detection and diagnosis (Computer Aided Detection or Diagnosis - CAD) is a tool for medical help that has been used to identify and diagnose abnormalities in breast tissue. Although CAD systems have provided a large number of research and increased sensitivity, the majority analyzes the MLO and CC views independently. Exper

2. Desenvolvimento de novas técnicas para redução de falso-positivo e definição automática de parâmetros em esquemas de diagnóstico auxiliado por computador em mamografia / Development of news technique for reduction of false-positive and automatic definition of parameters of mammograms for CAD schemes
This present work consists on the investigation of mammographic image characteristics for automatic determination of image processing parameters for a mammography computer aided diagnosis scheme (CAD) in order to get optimal performance. Additionally, using the results obtained on this first investigation, it was also developed a new technique for the reduct

4. Investigação do uso de imagens mamográficas adquiridas em diferentes digitalizadores no desempenho do processamento de imagens para detecção de microcalcificações / Investigation of the use of mammographic images digitized in different scanners for detection of clustered microcalcifications
This work is intended in comparing the results from a mammographic images processing scheme considering images sets digitized by a laser and by an optical scanners (Lumiscan50 and Umax Powerlook 1120 units, respectively). By means of a statistical analysis, we could verify that the optical scanner yields a remarkable increase in the digitized image intensity
