چکیده

When novel scenes are encoded, the representations of scene layout are generally viewpoint specific. Past studies of scene recognition have typically required subjects to explicitly study and encode novel scenes, but in everyday visual experience, it is possible that much scene learning occurs incidentally. Here, we examine whether implicitly encoded scene layouts are also viewpoint dependent. We used the contextual cuing paradigm, in which search for a target is facilitated by implicitly learned associations between target locations and novel spatial contexts (Chun & Jiang, 1998). This task was extended to naturalistic search arrays with apparent depth. To test viewpoint dependence, the viewpoint of the scenes was varied from training to testing. Contextual cuing and, hence, scene context learning decreased as the angular rotation from training viewpoint increased. This finding suggests that implicitly acquired representations of scene layout are viewpoint dependent.

A 2D + 3D Rich Data Approach to Scene Understanding

On your one-minute walk from the coffee machine to your desk each morning, you pass by dozens of scenes – a kitchen, an elevator, your office – and you effortlessly recognize them and perceive their 3D structure. But this one-minute scene-understanding problem has been an open challenge in computer vision since the field was first established 50 years ago. In this dissertation, we aim to rethin...

Comparing rapid scene categorization of aerial and terrestrial views: A new perspective on scene gist.

Scene gist, a viewer's holistic representation of a scene from a single eye fixation, has been extensively studied for terrestrial views, but not for aerial views. We compared rapid scene categorization of both views in three experiments to determine the degree to which diagnostic information is view dependent versus view independent.We found large differences in observers' ability to rapidly c...

Viewpoint Dependence in Human Spatial Memory

We summarize two lines of research that investigated whether human spatial memories are viewpoint dependent (e.g., viewer-centered reference frames) viewpoint independent (e.g., scene-centered reference frames). In one series of experiments, participants made judgments of relative direction after viewing a Sl~ti~_ I layout from one or two perspectives. The findings indicated that multiple views...

Implicit Learning of Viewpoint-Independent Spatial Layouts

We usually perceive things in our surroundings as unchanged despite viewpoint changes caused by self-motion. The visual system therefore must have a function to process objects independently of viewpoint. In this study, we examined whether viewpoint-independent spatial layout can be obtained implicitly. For this purpose, we used a contextual cueing effect, a learning effect of spatial layout in...

3 D Display Rendering Acceleration Using Occlusion Camera Reference Images

1 Abstract—volumetric 3D displays are an emerging technology that allows the user to explore a 3D scene free of joysticks, keyboards, goggles, or trackers. For non-trivial scenes, computing and transferring a 3D image to the display takes hundreds of seconds, which is a serious bottleneck for many applications. We propose to represent the 3D scene with an occlusion camera reference image (OCRI)...
