    摘要： A system for detecting and counting individuals in a stationary or moving crowd based on a digital or digitized image captured from a single camera. Initial information is assumed based on a foot-to-head plane homology, where a geometric construct is developed to best enclose image features with a high probability of being an individual within a crowd. These geometric constructs are then subjected to further probabilistic analysis to determine individuals. The vector track of each individual is determined to validate the determination of a group of features as individuals, thereby compensating for occlusion of an individual within any given frame image. A virtual gate is then employed to count the individuals moving past the virtual gate. Also, by weighting portions of the individual, events near the gate can be predicted.

    摘要： An advertising system is disclosed. In one embodiment, the system includes an advertising station including a display and configured to provide advertising content to potential customers via the display and one or more cameras configured to capture images of the potential customers when proximate to the advertising station. The system may also include a data processing system to analyze the captured images to determine gaze directions and body pose directions for the potential customers, and to determine interest levels of the potential customers in the advertising content based on the determined gaze directions and body pose directions. Various other systems, methods, and articles of manufacture are also disclosed.
