Abstract: Provided is a method for retrieving a lost-of-contact mobile terminal. The method is applied to a first control terminal, and includes: receiving a first lost-of-contact distress signal a first mobile terminal forwarded by a server; displaying a help seeking interface; sending, in response to a help-retrieving instruction, a first help-retrieving request to the server; and receiving a first confirmation help message from a second control terminal from the server, wherein the first confirmation help message indicates that the second control terminal agrees to help retrieve the first mobile terminal.

Abstract: Provided is a method for processing video data. The method includes: acquiring a second outline of at least one object in an (n+1)th image frame of a to-be-compressed video data group based on a fuzzy algorithm; determining a motion vector of the at least one object according to the second outline and a first outline of the at least one object in an nth image frame of the to-be-compressed video data group; acquiring compressed video data according to the motion vector and a start image frame of to-be-compressed video data; and sending the compressed video data to an apparatus for displaying images.

Abstract: Provided are a mixed reality display method, a mixed reality device, and a storage medium. The method includes: after receiving a mixed display signal, tracking the eyeballs of a user by means of an eyeball tracker, and determining a gaze point of the user on a display screen; determining, according to a correspondence between the gaze point and a sub-display region in the display screen, the sub-display region the user gazes; determining at least one first image sensor according to a correspondence between the sub-display region and an image sensor in an image sensor array, and adjusting the at least one first image sensor; and superimposing and rendering an environment image output by the image sensor array and a virtual image, and obtaining and displaying an MR image.

Abstract: A control method for display switching, an electronic device, and a storage medium are provided. The control method for display switching includes: establishing a first buffer and a second buffer at a kernel layer and initializing the first buffer; establishing a first service process and a second service process at a user layer, and controlling the first service process to render a first image according to a display parameter of a first buffer and transmit it to a display screen via the first buffer for display; and initializing the second buffer according to a switching instruction, and controlling the second service process to render a second image according to a display parameter of the second buffer and transmit it to the display screen via the second buffer so as to make the display screen switch to displaying the second image.

Abstract: This disclosure relates to an image segmentation method and apparatus and image three-dimensional reconstruction method and apparatus, and to the field of computer technology. The segmentation method includes: dividing pixels in an image to be segmented among different pixel sets, according to color gamut ranges to which pixel values of the pixels belong; determining matching between pixels in each pixel set according to pixel values; and performing image segmentation on the image to be segmented according to the matching.
