چکیده

Becoming familiar with an environment requires the ability to integrate spatial information from different views. We provide evidence that view combination, a mechanism believed to underlie the ability to recognize novel views of familiar objects, is also used to recognize coherent, real-world scenes. In two experiments, we trained participants to recognize a real-world scene from two perspectives. When the angular difference between the learned views was relatively small, the participants subsequently recognized novel views from locations between the learned views about as well as they recognized the learned views and better than novel views situated outside of the shortest distance between the learned views. In contrast, with large angles between training views, all the novel views were recognized less well than the trained views. These results extend the view combination approach to scenes and are difficult to reconcile with models proposing that scenes are recognized by transforming them to match only the nearest stored view.

View combination: a generalization mechanism for visual recognition.

We examined whether view combination mechanisms shown to underlie object and scene recognition can integrate visual information across views that have little or no three-dimensional information at either the object or scene level. In three experiments, people learned four "views" of a two dimensional visual array derived from a three-dimensional scene. In Experiments 1 and 2, the stimuli were a...

View combination in recognition of 3-D virtual reality layouts.

We investigated whether a normalization model or view combination model fit the performance of scene recognition of 3-D layouts using a virtual-reality paradigm. Participants learned a layout of seven objects from two training views (e.g., 0° and 48°) by discriminating the "correct" layout from distracters. Later, they performed a discrimination task using the training views (e.g., 0° and 48°),...

Novel-view scene recognition relies on identifying spatial reference directions.

Five experiments investigated whether observer locomotion provides specialized information facilitating novel-view scene recognition. Participants detected a position change after briefly viewing a desktop scene when the table stayed stationary or was rotated and when the observer stayed stationary or locomoted. The results showed that 49 degrees novel-view scene recognition was more accurate w...

Scene recognition following locomotion around a scene.

Effects of locomotion on scene-recognition reaction time (RT) and accuracy were studied. In experiment 1, observers memorized an 11-object scene and made scene-recognition judgments on subsequently presented scenes from the encoded view or different views (ie scenes were rotated or observers moved around the scene, both from 40 degrees to 360 degrees). In experiment 2, observers viewed differen...

Horror Video Scene Recognition Based on Multi-view Multi-instance Learning

Comparing with the research of pornographic content filtering on Web, Web horror content filtering, especially horror video scene recognition is still on the stage of exploration. Most existing methods identify horror scene only from independent frames, ignoring the context cues among frames in a video scene. In this paper, we propose a Multi-view Multi-Instance Leaning (MIL) model based on joi...

Group Behavior Recognition With Multiple Cameras

We propose in this paper an approach for recognizing group of people behaviors using multiple cameras with overlapping FOVs (Field Of View). In this context, Behavior recognition first relies on low level motion detection and frame to frame tracking which generate a graph of mobile objects for each camera. Second, to take advantage of all cameras observing the same scene, a combination mechanis...
