Methods and apparatus for flexible illumination in which two or more different wavelengths are used in the illumination system. An illumination source may be configured to emit light at two or more different wavelengths, either continuously or selectively. A method may be implemented in which a first wavelength is emitted for capturing an image or images for a first portion of algorithmic processing for biometric authentication, and a second wavelength is emitted for capturing another image or images for a second portion of algorithmic processing for biometric authentication. The camera may sequentially capture two or more images at different wavelengths. As an alternative, the camera may be configured to concurrently capture two or more images at different wavelengths.

A system and a method for determining an object has been on a vehicle seat of a vehicle are provided. The processing circuitry may determine if passengers of the vehicle have left the vehicle. The processing circuitry may determine if a temperature of a vehicle cabin of the vehicle meets a threshold of temperature. The temperature of the vehicle cabin to a first temperature may be adjusted. A temperature of resistive filaments of the vehicle seat of the vehicle to a second temperature may be adjusted. A thermal image of the vehicle seat with a reference thermal image of the vehicle seat may be compared. The processing circuitry may determine if the object has been left on the vehicle seat.

A system for detection and identification of objects and obstacles near, between or on railway comprise several forward-looking imagers adapted to cover each different range forward and preferably to be sensitive each to different wavelength of radiation, including visible light, LWIR, and SWIR. The substantially homogeneous temperature along the rail the image of which is included in an imager frame assists in identifying and distinguishing the rail from the background Image processing is applied to define living creature in the image frame and to distinguish from a man-made object based on temperature of the body. Electro optic sensors (e.g. thermal infrared imaging sensor and visible band imaging sensor) are used to survey and monitor railway scenes in real time.

A method of monitoring synthetic gas emissions comprises obtaining a gas concentration image within a first area of interest from an overhead image acquisition device, detecting from the gas concentration image at least one gas plume of a synthetic gas emission, quantifying an emission rate of the detected gas plume, estimating an estimated point source of the detected gas plume, and attributing the detecting gas plume to an actual point source. A corresponding system for monitoring synthetic gas emissions comprises a memory storing a gas concentration image of a first area of interest, and a processor communicatively coupled thereto and configured to detect from the image of the gas concentration at least one gas plume of a synthetic gas emission, quantify an emission rate of the detected gas plume, estimate an estimated point source of the detected gas plume, and attribute the detecting gas plume to an actual point source.

Techniques of estimating surface normals and reflectance from poorly-lit images includes using, in addition to an RGB image of a subject of a set of subjects, an image illuminated with near-infrared (NIR) radiation to determine albedo and surface normal maps for performing an image relighting, the image being captured with the NIR radiation from essentially the same perspective from which the RGB image was captured. In some implementations, a prediction engine takes as input a single RGB image and a single NIR image and estimates surface normals and reflectance from the subject.

A target and a method of calibration of an IR camera unit is disclosed. The target may include, a substantially flat metallic plate, such that a first surface of the metallic plate has a surface roughness of between N9 to N10; and a pattern made from a polymeric ink applied on the first surface. The method may include, receiving from an IR camera, included in the camera unit, an image of the target taken in the infrared spectrum; extracting parameters, related to the camera, form the image; and calibrating the camera based on the extracted first parameters.

A system and method for quantifying viewer engagement with a video playing on a display in a respondent household includes an agreed upon camera arrangement to monitor viewer engagement. The system and method includes the ability to determine what sources of content are being accessed by the household, and other data such as time of viewing, and source of content.

More secure authentication is enabled. A solid-state imaging device according to an embodiment includes: an image processing unit that includes a plurality of first pixels arranged in a matrix on a first surface and generates image data on the basis of a light amount of incident light incident on each of the first pixels; and an event signal processing unit that includes a plurality of second pixels arranged in a matrix on a second surface parallel to the first surface and generates event data on the basis of a luminance change of incident light incident on each of the second pixels, in which the plurality of first pixels and the plurality of second pixels are arranged on a single chip.
