Abstract: A method for sending an alarm message, and belongs to the field of computer technology. The method includes: acquiring a detection image (201) captured by an image capturing apparatus; determining a target detection area (202); and detecting a person's call status information corresponding to an image in the target detection area according to a preset on-the-phone determination algorithm model, and sending a first alarm message (203) to a server if the person's call status information shows that the person is on the phone.

Abstract: The present disclosure discloses a method and device for sending an alarm message, and belongs to the field of computer technology. The method includes: acquiring a detection image captured by an image capturing apparatus; detecting a face image area and a head and shoulder image area in the detection image based on a preset face and head and shoulder detection algorithm model; determining a target detection area in the detection image according to the detection results of both the face image area and the head and shoulder image area; and detecting a person's call status information corresponding to an image in the target detection area according to a preset on-the-phone determination algorithm model, and sending a first alarm message to a server if the person's call status information shows that the person is on the phone.

Abstract: Systems and methods are provided for hybrid video encoding. An example method includes: acquiring image information; extracting a background image based at least in part on the image information; detecting whether the background image is stable; and performing encoding switching between a background-based encoding method and a non-background encoding method based at least in part on the detection.
