Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0022] The current face detection algorithm cannot meet the real-time requirements in terms of speed. In addition, the accuracy rate is not very high, especially when the target moves quickly, or moves far or near, there will be a problem of large detection error. When the face remains still, the face frame will continue to shake (the face frame tracked by each frame has errors), which greatly affects the user experience.
[0023] In order to solve the above proble...

The invention discloses a face detection frame display method. The method comprises the steps of obtaining a reference detection frame of a face detection image; obtaining a transformation detection frame according to the reference detection frame; obtaining a to-be-trained image according to the transformation detection frame; judging whether each to-be-trained image includes the reference detection frame or not; labeling each to-be-trained image according to position data and a judgment result of each to-be-trained image; training a neural network model according to each to-be-trained imageand a training label to obtain a pre-trained face detection model; obtaining a target image in a to-be-detected video, and obtaining the reference detection frame of the target image; amplifying the reference detection frame to obtain an amplified detection frame; acquiring a to-be-detected image of a next frame, and intercepting a to-be-confirmed image according to the amplified detection frame;inputting the to-be-confirmed image into a pre-trained face detection model to obtain a face detection result; and if the to-be-confirmed image is determined to include the face image, taking the amplified detection frame as a face detection frame of the to-be-detected image. In the invention, a problem of shaking of the face detection frame can be effectively solved.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a face detection frame display method, an image processing device, equipment and a storage medium. Background technique [0002] At present, there are many methods for face tracking. One of the more common methods is to train a fast target detector during the tracking process to detect around the target, so that the target position can be quickly located and the target can be quickly tracked. . Face tracking technology is widely used in some scenes of real-time processing of faces. However, the current face detection algorithm, due to the error of face detection in each frame, will appear when the face remains still. The face frame keeps shaking, which greatly affects the user experience. Contents of the invention [0003] Based on this, it is necessary to address the above problems, and propose a method for displaying a face detection frame, an image process...
