Occlusions veineuses rétiniennes

Occlusion veineuse rétinienne et syndrome d'hyperviscosité

Les occlusions veineuses rétiniennes secondaires aux syndromes d'hyperviscosité sont rares. Plusieurs cas d'occlusion de la veine centrale de la rétine [OVCR] compliquant une hémopathie ont été décrits, principalement au cours des polycythémies primitives ou secondaires, des lymphomes ou des leucémies. A travers cette observation, nous rapportons le cas d'un patient qui présente une OVCR de l'œ...

Tracking Ants Through Occlusions

The automated tracking of social insects, such as ants, could greatly increase the speed and reliability of gathering data used in studying their complex behaviors. Recently, data association based multipleobject tracking approaches have shown promise in improving tracking during occlusion. However, due to the high density and occlusion rate present in ant video, tracking is still prone to (1) ...

Image Recognition with Occlusions

We study the problem of how to detect interesting objects appeared in a given image I Our approach is to treat it as a function approximation problem based on an over redundant basis Since the ba sis a library of image templates is over redundant there are in nitely many ways to decompose I To select the best decomposition we rst propose a global optimization procedure that considers a concave ...

Depth Layers from Occlusions

We present a method to extract relative depth information from an uncalibrated monocular video sequence. Our method detects occlusions caused by an object moving in a static scene to infer relative depth relationships between scene parts. Our approach does not rely on any strong assumptions about the object or the scene to aid in this segmentation into layers. In general, the problem of buildin...
