A multi-spectral light-field device, including an imaging component, arranged to image a light-field emitted by an object point of an object and for setting an input signal including a range of incidence angles on an optical filter. The optical filter has a transmission function depending on the incidence angles to transform the input signal into an output signal including a spectral distribution associated to an angular distribution. A micro-lens array is arranged to transform the spectral distribution of the output signal into a spatial distribution on an image plane. This multi-spectral light-field device is adapted to be integrated in a small, compact and/or handheld device, as a smartphone and also to deliver high resolution images. Also an imaging system which is a compact twin camera device. Also an object identification system allowing an image reconstruction in real-time on limited computational resources of a mobile device, by using a machine-learning module.

Particular embodiments may provide for a method of providing illumination for a vehicle. A user input related to controlling a headlamp assembly for a vehicle may be received. The headlamp assembly may comprise a laser-based lamp configured to provide broad-spectrum, incoherent white light for high-beam illumination, a laser-based infrared lamp, and a light sensor configured to capture images of objects illuminated by the headlamp assembly. Instructions to activate the headlamp assembly may be sent. Images of a scene illuminated by the headlamp assembly may be captured by the light sensor. An object of interest in the images of the scene may be detected. Generation of an alert to a driver of the vehicle regarding the one or more objects of interest may be facilitated.

The present invention is generally related to systems and methods for providing an improved authentication and verification system through the use of compiled user data and user location or traffic data from multiple channels of input. Multiple devices may be utilized by the system in order to receive and process data to authenticate user identities and verify the validity of account activity.

A method for monitoring one or more live cells includes capturing a non-fluorescence image of a sample that includes one or more live cells that further contain fluorescent protein-based nuclear translocation reporters (FTRs), capturing a fluorescence image of the FTRs in the live cell(s) in the sample, identifying, via a computational model, nuclear pixels of the non-fluorescence image that correspond to nuclei of the live cell(s), identifying, based on the nuclear pixels, first pixels of the fluorescence image that correspond to the nuclei and second pixels of the fluorescence image that do not correspond to the nuclei, and calculating, based on first intensities of the first pixels and second intensities of the second pixels, a metric representing a first amount of the FTRs located within the nuclei of the live cell(s) and a second amount of the FTRs not located within the nuclei of the live cell(s).

Various embodiments disclosed herein describe a divided-aperture infrared spectral imaging (DAISI) system that is adapted to acquire multiple IR images of a scene with a single-shot (also referred to as a snapshot). The plurality of acquired images having different wavelength compositions that are obtained generally simultaneously. The system includes at least two optical channels that are spatially and spectrally different from one another. Each of the at least two optical channels are configured to transfer IR radiation incident on the optical system towards an optical FPA unit comprising at least two detector arrays. One of the at least two detector arrays comprises a cooled mid-wavelength infra-red FPA. The system further comprises at least one temperature reference source or surface that is used to dynamically calibrate the two detector arrays and compensate for a temperature difference between the two detector arrays.
