[0016] The basis for detecting the presence of people in video streams
[0017] Computer vision algorithms for detecting human presence can be varied, with their own drawbacks and advantages. One technique detects the presence of a person by determining whether there is activity in the foreground, i.e. by comparing the frame with the background. Another technique detects the presence of a person by determining whether there is motion, i.e. by comparing a frame with a previous frame. Both foreground-based and motion-based techniques are simple, but either technique can generate false positives when there are moving non-human objects in the video stream, such as moving plants, tethered balloons moving through the air, and spinning fans. Therefore, neither technique can be used outdoors. While another technique detects human presence by analyzing frames for silhouette, shape, color or other signatures. Due to complex image processing algorithms, this technique can be computa...
