针对基于均值漂移的目标跟踪，提出了一种新的权值反投影方法。根据相似性评估中使用的每个特征的直方图箱的相对计数来计算权重。提出了一种融合方案，将不同特征的反投影权值组合在一起，从而增强被跟踪目标与背景之间的差异性。提出了一种计算参考窗口和候选窗口之间的总体相似度的机制，该机制不需要实际进行反投影，只需基于直方图箱计数进行少量计算。此外，参考窗口和候选窗口不需要具有相同的大小。与传统的基于均值漂移的跟踪方法相比，该方法具有更好的跟踪效果，特别是在目标运动速度较快、背景杂波较大的情况下。
A new scheme for back-projection of weights for mean shift based object tracking is proposed. Weights are calculated based on relative counts of histogram bins for each feature used in similarity assessment. A fusion scheme is proposed to combine the back-projected weights from different features, such that the dissimilarities between the object being tracked and the background are boosted. A mechanism is proposed to calculate the overall similarity between reference and candidate windows, without actually doing the back-projection, and just by few computations based on histogram bin counts. Moreover, the reference and candidate windows do not need to have the same size. The proposed scheme shows better tracking results compared to the traditional mean shift based tracking, especially in case of fast object movement and high background clutter.
