Robust video fingerprints based on subspace embedding
We present a novel video fingerprinting method based on subspace embedding. The proposed method is particularly robust against frame-rate conversion attacks and geometric attacks...

Structure-Based Document Model with Discrete Wavelet Transforms and Its Application to Document Classification
Term signal is an existing text representation that depicts a term as a vector of frequencies of occurrences in a number of user-defined partitions of a document. Although term si...

Hierarchical fusion of color and depth information at partition level by cooperative region merging
A high level scheme for information fusion to create hierarchical region-based image representations based on a region merging process is presented. The strategy is based on an it...

Text Clustering on Latent Thematic Spaces: Variants, Strengths and Weaknesses
Deriving a thematically meaningful partition of an unlabeled document corpus is a challenging task. In this context, the use of document representations based on latent thematic ge...

Two dimensional non-separable adaptive directional lifting structure of discrete wavelet transform
In this paper, we propose a two dimensional (2D) non-separable adaptive directional lifting (ADL) structure of discrete wavelet transform (DWT) and its image coding application. C...
