摘要： In the embodiments of the present application, a reference position of a second camera associated in the behavior analysis on a moving target is determined in a monitoring area of a first camera, a video image containing the moving target captured by the first camera is displayed, so that when the moving target moves into a range to which a reference position of a target camera belongs in the reference position of the second camera, the video image of the target camera can be displayed. Since the reference position of the second camera associated in the behavior analysis on a moving target is determined in the monitoring area of the first camera, it can be determined during the behavior analysis on a moving target, that the moving target will subsequently appear in a video image of a target camera according to the range of the reference position of the target camera into which the moving target in the video image of the first camera moves, thereby switching to the video image of the target camera for displaying, that is, the behavior analysis on the moving target can be continued, so as to complete the continuous behavior analysis on the moving target, and improve the accuracy of behavior analysis.

摘要： Embodiments of the present application disclose a fingerprint liveness detection method and device (100), and a storage medium, relating to the technical field of security. Zone division can be performed on a first fingerprint image and a second fingerprint image, so that a feature vector for multi-zone grayscale distribution is determined according to the divided zones, so as to perform fingerprint liveness detection through a fingerprint liveness detection model. The first fingerprint image indicates a red channel image, and the second fingerprint image indicates a blue channel image. For a non-living one's fingerprint, a grayscale value distribution pattern for zones within these two channel images is different from that of a living one's fingerprint. Therefore, through the feature vector for multi-zone grayscale distribution, whether grayscale distribution feature(s) of a living one's fingerprint exists in a fingerprint image can be determined, and further whether the fingerprint is of a living one can be determined, which is more secure.

摘要： Embodiments of the present application disclose an infrared temperature measurement method, apparatus, device, and storage medium, which relate to the field of image processing. The method comprises: determining a measurement temperature of a to-be-measured target based on a grayscale image captured to obtain a first measurement temperature; determining key point coordinates of the target based on a target image; determining a first distance based on the key point coordinates and configuration information of an infrared temperature measurement device, the first distance is a distance between the target and the infrared temperature measurement device; determining an actual temperature of the target based on the first measurement temperature and the first distance. In this way, the target image ranging and grayscale image temperature measurement can be combined, which not only reduces the influence of distance on the measurement temperature, but also avoids the problem of inaccurate measurement temperature when the distance does not meet the requirements, thus improving temperature measuring precision and temperature measuring efficiency.
