Abstract: A method and system for determining occupancy in a space, include determining presence of an occupant in a space based a signal from a PIR sensor monitoring the space and on analysis of an image of the space. Assigning different weights to the PIR signal and image analysis enables controlling a device in the space differently.

Abstract: Embodiments of the invention relate to a method for determining that an object in a sequence of images is a human. The method may include the steps of detecting an object in a first image from the sequence of images and assigning a first score to the object. The object is tracked to a second image from the sequence of images and a second score is assigned to the object in the second image. The second score is compared to a threshold that is inversely related to the first score and a determination that the object in the second image is a human is made based on the comparison.

Abstract: A method and system for detecting a person in an image of a space include determining a value of a parameter of an object in the image, wherein if the value exceeds a threshold the object is determined to be a person. If the object is located in a predetermined area in the image, then changing the threshold and determining that the object is a person based on the value of the parameter and the changed threshold.
