Abstract
At present, video target tracking mainly uses correlation filters and deep learning. In target tracking, deep learning often uses convolutional neural networks and has strong feature extraction capabilities. However, due to the large amount of computation required for deep learning, the GPU performance requirements are high, and the computation time is extended, resulting in unsatisfactory tracking speed. Therefore, it is common to apply correlation filters for processing. The more classical ones are the nucleation correlation filter KCF and the Kalman filter. Both processing speeds are significantly improved compared to deep learning. In comparison, the Kalman filter is more advantageous because the moving position of the adjacent frame target is larger or more extensive. Simulate the motion trajectory of the target by the given data, introduce noise as the observation trajectory, and then analyze the error before and after the filtering by Kalman filtering; fit the complex trajectory. The video target tracking program of the interactive multi-model Kalman filter is obtained, and the target tracking accuracy before and after the application of IMM improvement is analyzed.
