Abstract: The present application discloses a method and an apparatus for displaying an image based on privacy masking, which belong to the field of video monitoring. The method includes: acquiring a to-be-masked original image provided by an image capture terminal and privacy masking area information of the original image; wherein, the privacy masking area information is obtained by identifying the original image or is obtained from the image capture terminal and indicates an area in the original image which is required to be masked; determining whether the original image is required to be privacy-masked based on whether privacy unmasking permission information is stored; if the original image is required to be privacy-masked, performing privacy-masking on the original image based on the privacy masking area information to obtain a masked image, and displaying the masked image. In this way, the image capture terminal is only required to provide an original image without providing the original image and the masked image, so the costs of both storage and transmission are low, saving the storage resources and network resources of the image capture terminal.

Abstract: Embodiments of a surveillance method, apparatus, system, electronic device and computer-readable storage medium are provided. In the surveillance method, a non-visible light image and a target image are obtained, wherein the target image is generated from a visible light signal captured during a capture period of the non-visible light image. The method then detects whether an object is present in the non-visible light image. When an object is detected in the non-visible light image, a second location area of the object in a visible light image is determined according to a first location area of the object in the non-visible light image, such that surveillance of the object is implemented based on the visible light image, wherein the visible light image is an image determined based on the target image. Compared to the relevant art, the embodiments proposes to use the result of the object detection performed on the non-visible light image to determine the result of the object detection performed for the visible light image corresponding to the non-visible light image, which guarantees that the object detection result of the visible light image also has a high accuracy and thereby guarantees the effect of intelligent surveillance.
