Hunting is one of the human activities that directly affect wildlife and has received increasing attention given its socioeconomic dimensions. Most studies have been conducted on coastal and wetland areas and showed that hunting activity can greatly affect bird behaviour and distribution. Hunting-free reserves for game species are zones where birds find an area of reduced disturbance. We evalua...

4D object modeling, also called space-time modeling, allows to build animations with topological modifications, like metamorphosis or implicit surfaces, with high level control. Starting from a 4D objects modeler for animation, we propose a tool to manipulate 4D objects embedded on imported scenes, running on various OS and environments. Since the perception of 4D objects is complex, we propose...

Combined stereo and focus image series are fused for obtaining robust 3D information. The combination of depth from stereo and depth from (de)focus leads to good results also when dealing with scenes presenting periodical or weak structure. For analyzing the problem in ray optics, a signal model is presented which describes the imaging of a camera array taking into consideration a defocussed pr...

In our everyday world, we typically have an expectancy as to the kinds of scenes that we will see from one glance to the next. Also, many of the scenes that we do see are familiar in the sense that they have been experienced before. Do these factors influence the perception of a scene? In three experiments, priming subjects with a verbal descriptor of a scene was not found to improve reliably t...

Identifying a notable object and predicting its importance in front of vehicle are crucial for automated systems’ risk assessment decision making. However, current research has rarely exploited the driver’s attentional characteristics. In this study, we propose an attention-driven saliency estimation (SOE) method that uses attention intensity driver as criterion determining salience objects. Fi...

In this study, we used a hue scaling technique to examine human color constancy performance in simulated three-dimensional scenes. These scenes contained objects of various shapes and materials and a matte test patch at the center of the scene. Hue scaling settings were made for test patches under five different illuminations. Results show that subjects had nearly stable hue scalings for a give...
