This code is provided by Jun Wan. It is used in the Chalearn one-shot learning gesture challenge (round 2). This code includes: bag of features, 3D MoSIFT, EMoSIFT and SMoSIFT features.
If you use this code, you should cite these two papers.
1) Jun Wan, Qiuqi Ruan, Shuang Deng and Wei Li, "One-shot learning gesture recognition from rgb-d data using bag of features", journal of machine learning research, Vol 14, pp. 2549-2582, 2013.[link: http://jmlr.org/papers/volume14/wan13a/wan13a.pdf]
This paper introduces the 3D EMoSIFT features and also use SOMP to replace VQ for coding descriptors.
2) Jun Wan, Qiuqi Ruan and Wei Li, "3D SMoSIFT: 3D Sparse Motion Scale Invariant Feature Transform for Activity Recognition from RGB-D Videos", 2013, under review.
This paper introduces the 3D SMoSIFT features. The significant merit is that this new feature is almost real-time. And 3D SMoSIFT can get higher performance than 3D MoSIFT and 3D EMoSIFT features.
