1. Realce de contraste em imagens digitais usando equalização de histograma
Nowadays devices are able to capture and process images from complex surveillance monitoring systems or from simple mobile phones. In certain applications, the time necessary to process the image is not as important as the quality of the processed images (e.g., medical imaging), but in other cases the quality can be sacrificed in favour of time.This thesis f

2. TÃcnicas de Interferometria Ãptica aplicada à medicina, odontologia e comunicaÃÃes Ãpticas
In the work described in this thesis, we used two different interferometric techniques, the coherent optical frequency domain reflectometry (COFDR), and the optical coherence tomography (OCT). Both techniques are based on the Michelson interferometer. They were applied to optical communications and to medical and dentistry imaging. We will give a general des

4. Government health policy and the diffusion of new medical devices.
The combination of absent financial incentives, aspects of physicians' clinical training, and the uncertainty surrounding the appropriate application of expensive new medical devices have been the most significant factors in promoting their wasteful diffusion and use. This presentation summarizes the forces that have resulted in regulatory and reimbursement
