Abstract: Some embodiments of this specification provide face liveness detection computer-implemented methods, devices, and media. In an example, multiple face images continuously captured for a first user are obtained. Two face images are selected from the multiple face images for a target attribute in one or more predetermined image attributes, where a degree of difference between two attribute values of the target attribute corresponding to the two face images satisfies a predetermined criterion. Both of the two face images are input into a pre-trained face liveness detection model corresponding to the target attribute to obtain a detection result corresponding to the target attribute.

Abstract: A display system may include a wearable display for rendering three-dimensional virtual image content that appears to be located in an environment of a user of the display. The relative positions of the display and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the display. For example, the display-to-eye alignment may vary for different users and/or may change over time (e.g., as a user moves or as the display becomes displaced). The wearable device may determine a relative position and/or alignment between the display and the user's eyes by determining whether features of the eye are at certain vertical positions relative to the display. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, and position render camera(s) accordingly to present virtual image content.

Abstract: A braking method for a vehicle is provided. The method includes: determining a threshold of a braking energy recovery torque based on a driving mode; obtaining a braking request; determining a braking energy recovery torque value based on the braking request, where the braking energy recovery torque value is less than or equal to the threshold; and outputting a braking torque, where the braking torque is determined based on a total energy recovery torque value, and the total energy recovery torque value is a sum of the braking energy recovery torque value and a coasting energy recovery torque value. Because the braking torque output by a motor during braking may be decreased based on the threshold of the braking energy recovery torque, a probability of locking of a wheel can be reduced. This reduces a probability of triggering a chassis function and improves experience of a driver.

The display system may determine a relative position or alignment between the HMD and the user's eyes. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, may provide feedback on the quality of the fit to the user, and/or may take actions to reduce or minimize effects of any misalignment.

Abstract: Similarity-based deformable registration of medical images that contain tumor regions often undesirably leads to disproportionate volume changes to tumor regions. An image-registration framework for preserving tumor volumes while promoting similarity in non-tumor part is provided. The framework involves a two-stage process. In the first stage, similarity-based registration is used to identify potential tumor regions by their volume change, generating a soft tumor mask accordingly. In the second stage, a volume-preserving registration network is used. The network uses a novel adaptive volume-preserving loss that penalizes the change in size adaptively based on the masks calculated from the previous stage. The framework balances image similarity and volume preservation in different regions, i.e. non-tumor and tumor regions, by using soft tumor masks to adjust the imposition of volume-preserving loss on each one.
