Open-access operating algorithms for commercial videokeratographer and improvement of corneal sampling

We present an algorithm to process images of reflected Placido rings captured by a commercial videokeratoscope. Raw data are obtained with no Cartesian-to-polar-coordinate conversion, thus avoiding interpolation and associated numerical artifacts. The method provides a characteristic equation for the device and is able to process around 6 times more corneal data than the commercial software. Our proposal allows complete control over the whole process from the capture of corneal images until the computation of curvature radii.

Galeria de espelhos: figuras da representação em François Truffaut

Esta dissertação consiste numa análise de quatro filmes de François Truffaut, nomeadamente La mariée était en noir (1968), La sirène du Mississipi (1969), L’histoire d’Adèle H. (1975) e La chambre verte (1978). O meu estudo centra-se nalgumas figuras pertencentes a sistemas de representação, que ocupam posições de relevo nas narrativas e na imagética destes filmes. Assim, considero o tratamento dado a fotografias, pinturas, desenhos ou esculturas no quadro maior da imagem fílmica, e atento na caracterização de certas personagens enquanto, elas mesmas, propiciadoras de uma reflexão acerca da imagem. Finalmente, procuro repensar o modo como, associando esse trabalho sobre objectos representativos a um pensamento sobre a morte, Truffaut formula uma meditação sobre o cinema enquanto arte intimamente relacionada com a noção de fantasma.
