In this paper we propose to compare two region-based approaches to content-based video indexing and retrieval. Namely a comparison of a system using the Earth Mover's Distance and a system using the Latent Semantic Indexing is provided. Region based methods allow to keep the local information in a way that reflects the human perception of the content. Thus, they are very attractive to design efficient Content Based Video Retrieval systems. We presented a region based approach using Latent Semantic Indexing (LSI) in previous work. And now we compare performances of our system with a method using the Earth Mover's Distance that have the property to keep the original features describing regions. This paper shows that LSA performs better on the task of object retrieval despite the quantification process implied.
