Abstract

The invention discloses a visual significance-based interference sensing and tracking algorithm. The visual significance-based interference sensing and tracking algorithm comprises the steps of S1, inputting a video image; S2, representing the appearance model of a to-be-tracked target in the image by utilizing the characteristics of a gradient orientation histogram, and calculating to obtain a histogram disturbance model in the gradient direction; S3, calculating the output response and the context awareness correlation tracking response; S4, carrying out weighted fusion to obtain a target weighted response, adopting a position where the maximum response is located as the position of the to-be-tracked target, and estimating the target scale and the position change; S5, when the to-be-tracked target is shielded, calculating to obtain a visual saliency map, and estimating the position of the to-be-tracked target according to the position of a candidate target; S6, according to the condition of the to-be-tracked target, updating the appearance model and the disturbance model; S7, inputting the next frame of the image, and returning to the step S1. According to the algorithm, the problem in the prior art that the existing target tracking method is easily influenced by factors such as illumination change, low resolution, scale change, shielding, similar targets, noisy backgrounds and the like so as to cause the poor tracking effect can be solved.
