The present disclosure relates to a compressive sensing imaging system which may include a compressive sensing optic (CSO) that includes a plurality of compressive sensing elements (CSEs), a fiber optic bundle (FOB) that includes a plurality of fiber optic elements (FOEs) and a sensor that includes a plurality of optical sensing elements (OSEs). Each CSE is configured to capture a respective random CSE optical sample related to a respective portion of a scene and to provide the respective CSE optical sample to the FOB. Each FOE is configured to integrate one or more accepted scene optical samples to produce an associated compressed optical sample and each scene optical sample corresponds to at least a portion of a respective CSE optical sample. Each FOE is further configured to provide the associated compressed optical sample to the sensor. Each OSE is configured to integrate one or more received sensor optical samples.

Compressive sensing imaging system

A system and method for gaze detection of an animate subject, typically a human. The subject's pupils are located in three dimensional space, using red-eye detection techniques and triangulation. Then, the gaze direction is determined based on the shape of the subject's irises.

Eye location and gaze detection system and method

Embodiments of the invention provide a non-contact method for measuring the surface profile of an object that can include generating a point-type optical signal and projecting it on a rotatable precision optical grating, generating a rotating pattern of light and dark lines onto the object, recording a series of images of the rotating pattern moving across the object with an image receiving device and calculating the surface profile of the object. Other embodiments can include a method to calibrate the system and a non-contact apparatus that generally includes a point-type light source, a rotatably mounted optical grating being configured to project a moving grating image on the object, a processor in communication with the image capturing device and configured to receive image input from the image capturing device and generate a surface profile representation of the object therefrom.

Non-contact apparatus and method for measuring surface profile

Surveillance apparatus and methods effective for detecting incidents are based upon improved image processing techniques applied to infrared and visible light spectrum images in a time sequence. A reference image is generated by removing motion objects from an image of a region of interest. The reference image is compared to an image to be analyzed to detect motion. Detected motion is analyzed and classified as motion objects. The motion objects are then compared to a motion model, which classifies the objects as being anticipated or unanticipated.
