Even though the dynamicity of our environment is a given, much of what we know on fixation selection comes from studies of static scene viewing. We performed a direct comparison of fixation selection on static and dynamic visual stimuli and investigated how far identical mechanisms drive these. We recorded eye movements while participants viewed movie clips of natural scenery and static frames ...

A continuous one-dimensional scenery is a double-infinite sequence of points (thought of as locations of bells) in R. Assume that a scenery X is observed along the path of a Brownian motion in the following way: when the Brownian motion encounters a bell different from the last one visited, we hear a ring. The trajectory of the Brownian motion is unknown, whilst the scenery X is known except in...

Terrain generation algorithms have an important role in video games: they can provide a realistic scenario for the game experience, or can help keep the user interested in playing by providing new landscapes each time he plays. Nowadays there are a wide range of techniques for terrain generation, but all of them are focused on providing realistic terrains, often neglecting other aspects (e.g., ...

Westerners’ perceptions tend to focus on salient foreground objects, whereas Asians are more inclined to focus on contexts. We hypothesized that such culturally specific patterns of attention may be afforded by the perceptual environment of each culture. In order to test this hypothesis, we randomly sampled pictures of scenes from small, medium, and large cities in Japan and the United States. ...

A stable process in random scenery is the continuum limit of a class of random walks in random scenery that is described as follows. A random scenery on Z is a collection, {y(0), y(±1), y(±2), . . .}, of i.i.d. mean-zero variance-one random variables. Given a collection x = {x1, x2, . . . } of i.i.d. random variables, we consider the usual random walk n 7→ sn = x1+ · · ·+xn which leads to the f...

Research on methods for representing natural objects and phenomena by computer graphics (CG) has been steadily broadening the scope of represented objects in recent years. Among such research, visual simulation of rocky scenery is an important issue that has a wide range of applications related to visual contents, such as in landscape simulation. In the early days of research on terrain scenery...
