A handheld ultrasound device may comprise components configured to provide decreased size, weight, complexity, and power consumption. The handheld ultrasound device may comprise a beamformer configured to implement and compress a flag table in place of a delay table. These improvements can decrease the amount of memory used to generate ultrasound images, which can decrease the size, weight, and power consumption of the handheld ultrasound device. Ultrasound image data on a handheld imaging probe can be compressed on the handheld imaging probe prior to transmission from the probe in order to decrease the amount of data transmitted from the probe. The compressed data may comprise compressed pixels to maintain spatial image resolution. The compression circuitry may comprise an amount of memory related to a dynamic range of the compressed data that is independent of the dynamic range of the input data, which can decrease memory, power consumption, and latencies.

An auxiliary filtering device for face recognition is provided. The auxiliary filtering device is used to exclude an ineligible object to be identified according to the relative relationship between object distances and image sizes, the image variation with time and/or the feature difference between images captured by different cameras to prevent the possibility of cracking the face recognition by using a photo or a video.

Methods and systems to synthesize information from multiple discrete and unrelated documents, and from the synthesized information verify the identity of an individual to a high degree of trust are described. Information is adaptively synthesized from varied documents, and through generation of document confidence scores. Enrollment requirements for a trusted identification are evaluated in a real-time environment. The enrollment requirements may represent a minimum level of documentation required to sufficiently verify an individual's true identity in order to permit issuance of the trusted identification. Once sufficient documentation has been obtained and validated to meet or exceed enrollment requirements, the documentation (including any original source copies of any documentation) is securely submitted to the trusted identification issuing authority.

In a facial skin detection method performed by a terminal device having a front-facing camera, a first image including a face is obtained and feature information of pores in a target area of the face is extracted. The pores in the target area are classified into pore categories based on the feature information of the pores in the target area. Feature information of pores of each pore category is input into at least one pore detection model to obtain pore detection data of each pore category and a skin detection result of the face is determined based on pore detection data of the pore categories.

Methods and devices related to determining image sensor settings using LiDAR are described. In an example, a method can include receiving, at a processing resource via a LiDAR sensor, first signaling indicative of location data, elevation data, and/or light energy intensity data associated with an object, receiving, at the processing resource via an image sensor, second signaling indicative of data representing an image of the object, generating, based at least in part on the first signaling, additional data representing a frame of reference for the object, transmitting to a user interface third signaling indicative of the data representing the frame of reference for the object and the data representing the image of the object, and displaying, at the user interface and based at least in part on the third signaling, another image that comprises a combination of the frame of reference and the data representing the image.

A display screen, comprising a panel (1), a light-emitting plate (2), a light blocking film (3) and an image sensor (4) that are stacked sequentially. The light blocking film (3) is provided with a light-transmitting imaging pinhole (31); the light-emitting plate (2) is provided with a plurality of light-emitting units (21) and a circuit network (22) for driving each of the light-emitting units (21), wherein the circuit network (22) divides the light-emitting plate (2) into a plurality of light-transmitting regions (23), and a light path is formed by the panel (1), the light-transmitting region (23) corresponding to a position of the imaging pinhole and the imaging pinhole (31); alternatively, the light-emitting plate (2) is a plane light-emitting plate which is light-transmissive, and a light path is formed by the panel (1), the plane light-emitting plate and the imaging pinhole (31); and a part of light projected by the light-emitting plate (2) toward the panel (1) is reflected by a target object located on or outside the panel (1), and then irradiated onto the image sensor (4) through the light path. According to the principle of pinhole imaging, the light passing through the imaging pinhole (31) can image on the image sensor (4), thereby enabling the display screen to have both a display function and an image acquisition function.

A mobile terminal to be carried by a user of a vehicle acquires a captured image of the vehicle, acquires distance information on a distance to the vehicle based on the captured image, determines whether the distance to the vehicle is within a predetermined allowable distance based on the distance information, and transmits an operation signal corresponding to an operation content input by a user to the vehicle when the distance to the vehicle is determined to be within the allowable distance.

A method for inserting a virtual object into a virtual environment is provided, including: generating a scan of a real world object; processing the scan to identify a type of the real world object; based on the identified type of the real world object, generating a virtual object that resembles the real world object; based on the identified type of the real world object, assigning a functionality to the virtual object, the functionality defining an action capable of being performed by the virtual object in a virtual environment; deploying the virtual object in the virtual environment.

A data collection apparatus comprises a camera configured to obtain first and second recordings of at least a portion of a medicament delivery device, said portion including a first component and a second component, the first component being configured to move relative to the second component as medicament is expelled from the medicament delivery device. The data collection apparatus also comprises a processing arrangement configured to determine, from said first and second recordings, positions in the first and second recordings of the first component relative to the second component, and determine an amount of medicament that has been expelled by the medicament delivery device by comparing the position, in the first recording, of the first component relative to the second component with a position, in the second recording, of the first component relative to the second component.
