A vehicle monitoring system includes at least one camera, and a server that is communicably connected to a client terminal. The camera performs capturing a vehicle while switching a first capturing condition including an image parameter for capturing a number of the vehicle entering an angle of view of the camera and a second capturing condition including an image parameter for capturing an occupant's face of the vehicle, and transmits a first captured video under the first capturing condition and a second captured video under the second capturing condition to the server. The server arranges reproduction screens for the first captured video and the second captured video that are reproduceable in the client terminal and displays the reproduction screens on the client terminal based on the first captured video and the second captured video.

Provided is a display panel having a display region and a non-display region, and the display panel includes: a substrate; light-emitting elements disposed at a side of the substrate and located in the display region, each of light-emitting elements includes a light-emitting layer; and a light-shielding layer disposed at a side of the light-emitting elements facing away from the substrate, the light-shielding layer includes first apertures, and in a direction perpendicular to the substrate, each first aperture does not overlap with the light-emitting layer. In an embodiment, a distance between a first point on an edge of a first orthographic projection and a second point on an edge of a second orthographic projection is defined as a distance L, which satisfies

[00001]$L\ge \frac{d\times \sin \theta }{\sqrt{n^2-{\sin }^2\theta }},$

where d denotes a distance between the light-emitting layer and the light-shielding layer, n denotes a refractive index of a functional film layer, θ denotes a visible angle and 0°<θ<90°.

Methods, systems, apparatus, and computer-readable media for data band selection using machine learning. In some implementations, image data comprising information for each of multiple wavelength bands is obtained. A multi-layer neural network is trained using the image data to perform one or more classification or regression tasks. A proper subset of the wavelength bands is selected based on parameters of a layer of the trained multi-layer neural network, where the parameters were determined through training of the multi-layer neural network using the image data. Output is provided indicating that the selected wavelength bands are selected for the one or more classification or regression tasks.

Methods, apparatus, systems, and articles of manufacture are disclosed. An example apparatus includes a thermal image detector to determine a heat blob count based on a frame of thermal image data, the frame of thermal image data captured in the media environment, a comparator to compare the heat blob count to a prompted people count, the prompted people count based on one or more responses to a prompting message, and when the heat blob count and the prompted people count match, cause a timer that is to trigger generation of the prompting message to be reset.

A biometrics imaging device for capturing image data of a body part of a person comprises a visible light sensor for capturing image data of the body part in the visible light spectrum and/or a near infrared light sensor for capturing image data of the body part in the near infrared light spectrum.
