A Hamming Embedding Kernel with Informative Bag-of-Visual Words for Video Semantic Indexing
Feng Wang, Wan-Lei Zhao, Chong-Wah Ngo, Bernard Merialdo
Article No.: 26
In this article, we propose a novel Hamming embedding kernel with informative bag-of-visual words to address two main problems existing in traditional BoW approaches for video semantic indexing. First, Hamming embedding is employed to alleviate...
We propose a steganalytic algorithm for triangle meshes, based on the supervised training of a classifier by discriminative feature vectors. After a normalization step, the triangle mesh is calibrated by one step of Laplacian smoothing and then a...
