Problems solved by technology

[0003] However, if the face moves quickly, the face in the video frame will appear blurred, and the existing tracking algorithm is prone to failure when tracking the blurred face, resulting in the loss of tracking of the blurred face
In this case, it will not be possible to perform special effects rendering on blurred faces that are lost in tracking, which will undoubtedly affect the effect of special effects rendering on faces

Abstract

The embodiment of the invention provides a face tracking method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining the position information of a first tracking frame when a face of a video is tracked, and if a lost target face is tracked in any current video frame; magnifying the area selected by the first tracking frame according to the target magnification times to obtain the magnified first tracking frame; determining an area corresponding to the amplified first tracking frame in the current video frame according to the position information of the amplified first tracking frame; intercepting an image in the area from the current video frame as a local image corresponding to the amplified first tracking frame; detecting whether a human face exists in the local image; and if so, generating a second tracking frame at the position corresponding to the face in the current video frame, and taking the second tracking frame as a face tracking result in the current video frame. According to the scheme, the target which fails to be tracked in the tracking process can be effectively tracked.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a face tracking method, device, electronic equipment and storage medium. Background technique [0002] In order to perform special effect rendering on the human face in the video frame of the video, it is first necessary to detect and track the human face in the video frame, and then perform special effect rendering on the detected and tracked human face. [0003] However, if the face moves quickly, the face in the video frame will be blurred, and the existing tracking algorithm is prone to failure when tracking the blurred face, so the tracking of the blurred face will be lost. In this case, it will not be possible to perform special effect rendering on the blurred face that is lost in tracking, which will undoubtedly affect the effect of special effect rendering on the human face. Contents of the invention [0004] The purpose of the embodiments of the pre...
