System and method of image-based space detection
First Claim
1. An image-based space detection system, comprising:
- an image capturing and processing device for capturing and processing images of a plurality of image processing areas and selecting from said captured image processing areas at least an image processing area affecting space status determination;
a 3-layer detection mechanism having an observation layer, a labeling layer and a semantics layer, said 3-layer detection mechanism being coupled to said image capturing and processing device, observing information of said selected image processing areas, combining a local classification model, an adjacent local constraint model and a global semantics model to fully describe probability distribution of link relation between layers of said observation layer, said labeling layer and said semantic layer, and providing global labeling constraint information; and
a computing device connected to said 3-layer detection mechanism, for analyzing said probability distribution and said global labeling constraint information, and generating image-based optimal space detection result.

Abstract
Disclosed is a system and method of image-based space detection. The system includes an image selection module, a 3-layer detection mechanism and an optimization module. At least one image processing area that may affect space-status judgment is selected from plural image processing areas. The 3-layer detection mechanism having an observation layer, a labeling layer, and a semantic layer observes the information about the selected image processing area, associates with a local classification model, and adjacent local constraint model and a global semantics model to completely describe the probability distribution of the links among the three layers, and provide global label constraint information. The optimization module analyzes the probability distribution and global label constraint information, and generates an image-based optimized space detection result.
