Ã. O. Rodrigues, A. Conci, F. F. C. Morais +1
The amount of fat on the surroundings of the heart is correlated to several health risk factors such as carotid stiffness, coronary artery calcification, atrial fibrillation, ather…
ROI Extraction in Thermographic Breast Images Using Genetic Algorithms
LC Mendes, EO Rodrigues, Sandro C Izidoro +2
This work proposes the use of Genetic Algorithms (GA) to identify the area of the breast from the background in thermographic breast images. The proposed method uses color informat…
Fractal triangular search: a metaheuristic for image content search
Erick O. Rodrigues, Panos Liatsis, Luiz Satoru +1
This work proposes a variable neighbourhood search (FTS) that uses a fractal-based local search primarily designed for images. Searching for specific content in images is posed as…
