A motion sensor for detection motion of humans is provided. The motion sensor contains a near infrared (NIR) low resolution image sensor that captures image frames in the near infrared spectrum and a sensor that detects the amount of visible light. In addition, a processor is connected to the visible light sensor and the NIR motion sensor. The processor is configured to receive the amount of visible light from the visible light sensor and the images from the NIR low resolution image sensor. The processor is further configured to compare the image frames to detect motion; the sensitivity of the detection of motion is determined by the amount of visible light detected by the visible light sensor. The output has two or modes based on the detection of motion by the processor.

Method to customize an application associated with a television experience based on the recognition of users located in front of a display and in the field of view of a camera, comprising the following steps: —an initialization step during which each user is enrolled in a database of a computer system and is defined by a profile referenced by a profile ID and comprising the user name, biometric data and additional personal data, —a finding step during which a wide image, acquired by said camera is scanned to isolate at least one user's faces, to define a marking area surrounding it, to memorize the position of said marking areas, —a matching step to extract the biometric data from said marking area, to match them with the biometric data of the profiles stored in the database, and to assign the detected profile ID with the marking area. While subsequent identification is requested by the application, the following steps are executed —acquiring a wide image with the camera, —extracting the areas of said image according to the marking areas, —extracting for a particular marking area the biometric data of a face, —starting the comparison of the extracted biometric data with the biometric data of the profile ID related to this marking area, and in absence of match, continuing with the other biometric data of the database until one profile is found, —transmitting the found profile ID to the application.

The system and method for hyperspectral target identification provides for sue of a sensor array such that for a 2 by 2 pixel, each pixel is set to a different wavelength by employing a band pass filter, so that one can determine whether a cluster set is of a natural object or a man-made object. Using ratios of the collected energy within the partitioned sub-bands one can make near real-time declarations about targets and in some cases, friend or foe determinations.

A light source (11) of a disguising mask detecting device (1) emits light at a person who is a subject. A camera (12) acquires images in multiple different wavelength ranges of reflected light of the light emitted at the person. A face detector (172) detects a face region of the person from the images acquired by the camera (12). A determiner (173) determines that the person is wearing a disguising mask when luminances of the face region in the images satisfy specific relations different from relations exhibited by skin.

The inventors of the present application developed novel optically active materials, methods, and systems for reading identifying information on an optically active article.
