A new time-sequential approach for motion layer extraction is presented. We assume that the scene can be described by a set of layers associated to affine motion models. In one o...

—Reduced Resolution Update (RRU) video coding provides a better compression performance than H.264/AVC does. It is implemented by encoding the predicted residuals after downsampl...

Background: Leishmania and other members of the Trypanosomatidae family diverged early on in eukaryotic evolution and consequently display unique cellular properties. Their appare...
