摘要: 针对实时目标跟踪会产生跟踪不稳定、易漂移、被遮挡就丢失的问题,提出改进的多样本跟踪算法。在压缩传感实时跟踪中,通过增加随机测量矩阵产生新的压缩感知特征,融合多个正负样本。结合boosting学习方法更新特征权值并改进置信图估计,解决目标漂移和丢失问题。实验结果表明,该方法在目标运动、纹理和环境显著变化以及被部分遮挡的情况下,跟踪的鲁棒性依旧很高,能达到稳定、实时的目标跟踪。

Abstract: Aiming at the problems of unstable tracking, easy to drift, obscured loss, which are produced in real-time target tracking, we propose an improved tracking algorithm for multiple instances. In the compressed sensing and real-time tracking, by adding random measurement matrix to produce new features, multiple positive and negative instances are integrated. By combining with the boosting learning method to update the feature weights and improve the confidence map estimation, we solve the problems of target drift and loss. Experimental results show that the proposed algorithm achieves better robustness and stable real-time tracking when the target moves quickly, or in conditions that the textures and lightings change seriously, as well as it is partially covered.

Key words: target tracking, compressive sensing, multiple instance, real-time tracking, drift, target occlusion
