Information generation method and device

Abstract

The embodiment of the present application discloses an information generation method and device. A specific embodiment of the method includes: acquiring the image to be detected and the first area position information used to define the face area in the previous frame image of the image to be detected; The key point positioning operation is to obtain the coordinates of each key point of the face included in the image to be detected; based on the coordinates of each key point of the face, determine the second area position information used to limit the face area in the image to be detected; generate Correspondence information between the detection image and the location information of the second area. This embodiment enables targeted information generation.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and in particular to an information generation method and device. Background technique [0002] Existing tracking methods for targets (such as target faces, etc.) are usually correlation-based tracking methods. For example, through some correlation judgment methods, the targets of different frames are connected in series to obtain the target tracking information. But the existing object tracking methods have the problem of poor robustness. For example, when a non-target and a target are occluded, it often causes the temporary disappearance of the target. Or when the target approaches or moves away from the camera quickly, the size of the target may suddenly increase or decrease, which is easy to lose. When the target appears again, it is often impossible to continue to track the target accurately. Contents of the invention [000...
