Embodiment Construction

[0045] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0046] The present invention proposes an image sequence target detection and tracking algorithm based on super-resolution enhancement and variable template matching. Before tracking the target in the image sequence, the algorithm uses a nonlinear iterative method to increase the The resolution reconstruction step significantly improves the image quality, and also has a positive effect on the subsequent target tracking. Experiments show that this algorithm has a good target tracking and matching effect and has a good application prospect.

Abstract

The present invention discloses a target tracking method based on super-resolution reconstruction. The method comprises the steps of firstly utilizing a nonlinear iteration algorithm to carry out the super-resolution reconstruction on a low-resolution image of a target image sequence; secondly, standardizing the image after the super-resolution reconstruction and determining a desired motion target area; finally, combining a variable template method to detect and track a target in the desired motion target area. The target tracking method based on the super-resolution reconstruction of the present invention better solves the detection difficulty caused by the deformation in the target motion, and is good in detection and tracking effects.

Description

technical field [0001] The invention relates to a target tracking method, in particular to a target tracking method based on super-resolution reconstruction, and belongs to the technical field of information perception and recognition. Background technique [0002] With the development of pattern recognition and various intelligent system technologies, dynamic target recognition technology has been widely used. Moving target detection and tracking based on image sequences refers to real-time detection of moving targets in image sequences and tracking of them. Object detection refers to the process of determining the position and size of an object in a given image. The methods in the literature mainly include: methods based on heuristic rules, methods based on features, methods based on clustering learning, and methods based on artificial neural networks. Object detection techniques can be used to search for the initial position of an object in an image sequence, and can al...
