Sensible Scenes : Visual Understanding of Complex

Visual Understanding of Complex Structures through Causal Analysis Matthew Brand, Lawrence Birnbaum, and Paul Cooper Northwestern University The Institute for the Learning Sciences 1890 Maple Avenue, Evanston IL 60201 [email protected] Abstract An important result of visual understanding is an explanation of a scene's causal structure: How action|usually motion|is originated, constrained, and p...

Understanding Descriptions of Visual Scenes Using Graph Grammars

Teaching computers to understand the meaning of natural language text has long been an important goal for Artificial Intelligence. The focus of my work is on the interpretation of descriptions of visual scenes such as ‘A man is sitting on a chair and using the computer’. One application of this research is the automatic generation of 3D scenes (Coyne and Sproat 2001), such as the one in Figure ...

Understanding dynamic scenes

We propose a framework for the representation of visual knowledge in a robotic agent, with special attention to the understanding of dynamic scenes. According to our approach, understanding involves the generation of a high level, declarative description of the perceived world. Developing such a description requires both bottom-up, data driven processes that associate symbolic knowledge represe...

Visual Perception: Objects and Scenes

Visual memory for moving scenes.

In the present study, memory for picture boundaries was measured with scenes that simulated self-motion along the depth axis. The results indicated that boundary extension (a distortion in memory for picture boundaries) occurred with moving scenes in the same manner as that reported previously for static scenes. Furthermore, motion affected memory for the boundaries but this effect of motion wa...
