Embodiment

[0013] The present invention mainly uses the multi-frame object detection results in continuous frame video as a reference to calculate the relationship between the object detection results of the current input frame and the previous frame and multi-frame object detection results. The compensation method makes the corresponding final detection position information more accurate.

[0014] In the present invention, it does not involve the writing or training of object detectors and the specific implementation of object tracking. Our method is to improve the display effect of object detection and tracking in videos. There are no special requirements or improvement requirements for object detectors. It only needs to calculate the input digital image matrix to obtain the object detection result, which is the object detector satisfying the method.

[0015] Such as figure 1 As shown, the detailed implementation steps of an improved video face detection and tracking effect method are...

Abstract

The invention relates to a position compensation method for fast moving object tracking in a video. The multi-frame object detection result in the continuous frame video is used as a reference, the relation between the object detection result of the current input frame and the object detection result of the previous frame and the multi-frame is calculated, and when the object rapidly moves, the corresponding final detection position information is more accurate by means of calculation and compensation addition. According to the method, the simple mathematical operation is used for carrying outresult association calculation between upper and lower frames on object detection in a video, so that the situation that a detection frame cannot follow up due to high speed in the detection trackingprocess is avoided. Offsets are calculated on the basis of the weights and the objects storing the FPS number, and better excessive smoothness can be obtained compared with direct averaging. The complex noise reduction and other processing do not need to be carried out on an input image, no special requirement is needed for an object detector, and the detection rate can be greatly increased, andenough computing efficiency can be ensured in low-end embedded equipment.

Description

technical field [0001] The invention relates to a position compensation method for fast moving object tracking in video. Background technique [0002] With the development of computer hardware and software technology, computer vision technology has received more and more attention. Especially in military, aerospace, computer-aided design, intelligent robot and other fields, computer vision technology has been widely used. In computer vision technology, the vision technology based on video image sequence is the most important, so it has become the focus and difficulty of people's research. The detection and tracking of moving objects in video sequences is the foundation and key of computer vision technology based on video sequences. First of all, whether the moving target can be accurately detected from the video image sequence is the key to the success of subsequent processing such as motion estimation, target recognition and behavior understanding. In order to realize th...
