Object tracking with hyperspectral videos (HSVs) offers significant advantages due to the captured spectral fingerprint information, which provides detailed physical material characteristics. While correlation filter (CF)-based tracking methods align well with the high-dimensional nature of HSVs, they often fall short of fully utilizing the spatial-spectral-temporal structure inherent in these data. In this article, we introduce a spatial-spectral-temporal CF (SSTCF) framework to address these limitations. SSTCF employs the spatial-spectral histogram of gradients and fractional abundances as features to characterize the spatial-spectral structure of the object. A low-rank constraint is integrated into the CF framework to enhance the global spectral semantic dependencies among learned filters. In addition, a temporal constraint is incorporated to ensure filter consistency across consecutive frames, further improving tracking continuity between nearby frames. Extensive experiments demonstrate that our SSTCF tracker achieves more accurate and stable performance. The source code will be publicly available at https://github.com/bearshng/SSTCF
