Computer algebra is applied to biomedical computer vision. Specifically certain biomedical images resulting from a case of rhinocerebral mucormysocis in a diabetic boy are analyzed using techniques in computational geometry ...

La restauración de imágenes consiste en recuperar, de la mejor manera posible la imagen original, a partir de su correspondiente imagen degradada (fotografía borrosa) y del conocimiento a priori de las causas de la ...

Na indústria de óleo e gás, a Inversão Sísmica é uma etapa de grande relevância para a caracterização dos reservatórios, pois é o processo pelo qual se obtém os modelos de propriedades de rocha na subsuperfície. Um aspecto ...

Retinal images are often degraded with a blur that varies across the gield view. Because traditional deblurring algorithms assume the blur to be space-invariant they typically fail in the presence of space-variant blur. ...

Image acquisition processes usually add some level of noise and degradation, thus causing common problems in image restoration. The restoration process depends on the knowledge about the degradation parameters, which is ...

Low-level vision is a processing system that plays an important role in human as well as in machine visual pattern recognition. It is often used to refer to information processing based on local visual features such as ...

Retinal images are essential clinical resources for the diagnosis of retinopathy and many other ocular diseases. Because of improper acquisition conditions or inherent optical aberrations in the eye, the images are often ...

The present work introduces an alternative method to deal with digital image restoration into a Bayesian framework, particularly, the use of a new half-quadratic function is proposed. The Bayesian methodology is based on ...
