MOVABLE OBJECT STATUS DETERMINATION |
摘要 |
<p>Embodiments of the present invention relate to automated methods and systems for determining a degree of presence of a movable object in a physical space. Video images are used to define a region of interest (1305) in the space and partition the region of interest into an array of sub-regions (1310). Then, first and second spatial-temporal visual features are determined, and metrics are computed (1320), (1340), to characterise whether or not each sub-region contains a moving or stationary object. The metrics are used to generate (1350) an indication of the overall degree of presence within the region of interest.</p> |
