Calculating ambient light in a space by obtaining a top view image of the space from an array of pixels, and identifying an object in the image and assigning weights to pixels from the array of pixels based on locations of the pixels relative to the identified object in the image, where object may include a reflective surface, where ambient light in the space is calculated based on the weighted pixels.

Method and system for calculating ambient light

Methods and systems according to embodiments of the invention calculate ambient light in a space, where the method includes obtaining an image of the space from an array of pixels, defining a plurality of pixel groups in the image, calculating a representative pixel value for each of the pixel groups, and calculating ambient light in the space based on the pixels in the image, disregarding pixels from the pixel groups having the highest and lowest representative pixel values.

A system and method for computer vision based tracking of a human form may include detecting a shape of an object in an image of a space and determining the probability of object having a human form shape based on movement of the object. If the probability of the object of being of a human form is above a predetermined threshold the object is tracked and if the probability is below the threshold then the tracking is terminated. Occupancy in the space may be determined based on the tracking of the object.

System and method for computer vision based tracking of an object

A system and method for computer vision based tracking of a human form may include receiving a sequence of images, the images including at least one object having a shape of a human form. A first selected feature is tracked from within the human form shaped object. Shape recognition algorithms are applied at a suspected location of the human form shaped object in an image from the sequence of images to detect a shape of a human form in the image and a second feature from within the detected shape of the human form is then selected and tracked, thereby providing verification and updating of the location of the human form shaped object.
