2008
Proceedings of the 2008 international conference on Content-based image and video retrieval - CIVR '08
Preserved Fulltext
The performance of these continuous vocabulary models are compared in an automatic scene recognition task. ...
Our experiments clearly show that the continuous approaches outperform the standard pLSA model. ...
In the next section we will then present the continuous vocabulary pLSA models and explain how the scene recognition system is modified when using a continuous visual vocabulary pLSA model instead of the ...
