Embodiment Construction

[0019] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0020] In recent years, with the rapid development of network technology, webcasting has been favored by users. Users can share their life, work and travel anecdotes by shooting short videos and posting them to the webcast platform. In order to enhance the interest of the short video, special effects can be added during the shooting of the short video, such as special effects controlled by human hands or faces. In order to ensure that the user can accurately control the special effects through the hand or face, it is necessary to track the user's hand or face and its changes during the shooting process.

[0021] As a way, according to the previous frame of human hand d...

Abstract

The invention discloses a target object tracking method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a first target object detection framefrom a first specified frame image of a to-be-processed video image, acquiring a to-be-tracked target object image corresponding to the first to-be-tracked video image based on the first target object detection frame, inputting the to-be-tracked target object image into a specified detection model, acquiring a target tracking frame output by the specified detection model, acquiring a second target object detection frame from a second specified frame image, acquiring an intersection ratio of the second target object detection frame to at least one target object tracking frame, performing smoothing processing on the second target object detection frame based on the first target object tracking frame corresponding to the intersection ratio with a numerical value greater than or equal to a preset threshold to obtain a reference target object detection frame, and tracking a second to-be-tracked video image corresponding to the first target object tracking frame based on the reference target object detection frame. According to the invention, calculation complexity in the tracking process of the target object tracking frame is reduced, and tracking continuity is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically, to a method, device, electronic device and storage medium for object tracking. Background technique [0002] Short video is a short video, which is a way of disseminating Internet content. Generally, it is a video with a duration of less than 5 minutes that is disseminated on new Internet media; Favored by big platforms, fans and capital. In order to enhance the interest of the short video, special effects can be added during the shooting of the short video, such as special effects controlled by human hands or faces. As a way, in order to ensure that the user can accurately manipulate special effects through the human hand or face, it is necessary to track the user's human hand or face and its changes during the shooting process. However, the existing hand or face tracking models have a complex calculation process and a huge amount of calculation, which...
