A plenoptic camera is a device which samples the light field using a microlens grid positioned in front of the CCD sensor. This grid consists of several microscopic lenses (often of the order of 100 000) with tiny focal lengths. The microlens divides what would become a 2D pixel in an ordinary camera to a set of rays of light just before reaching the sensor. The raw image that results ...
Image degradation due to heartbeat and respiratory motion is a major problem in MRI cardiac exams. Many strategies have been developed by the scientific community to handle breathing and heartbeat motion including cardiac gating, tracking, and breath-held cine imaging. However, breath-held protocols can only be

An important goal for Electroencephalogram-based functional brain studies is to identify the location of brain sources that produce the scalp-recorded signals. This task requires accurate identification and position of all Electroencephalogram (EEG) electrodes fixed on the scalp. The most widely used method is currently the electromagnetic digitization technique where a ...
Shape-from-Shading is a Computer Vision technique that aims to infer shape from the brightness map (i.e. intensity values) of the image assuming some simple mathematical models for the interaction between the light source, the surface shape, and the viewer’s position.
On the other hand, Image Synthesis, which is in some ...
