Risk-distortion analysis for video collusion attack
Collusion attack is a cost-effective attack against digital fingerprint. To develop an efficient collusion-resistant fingerprint scheme, it is very important for the detector t...

Multi-flow attack resistant watermarks for network flows
In this work we present a Multi-flow Attack Resistant Interval Centroid Based Watermarking (MAR-ICBW) scheme for network flows. Our proposed scheme can withstand the newly intro...

Robust discriminative keyword spotting for emotionally colored spontaneous speech using bidirectional LSTM networks
In this paper we propose a new technique for robust keyword spotting that uses bidirectional Long Short-Term Memory (BLSTM) recurrent neural nets to incorporate contextual informa...

Distance blurring for space-variant image coding
We present a novel selective blurring algorithm that mimics the optical distance blur effects that occur naturally in cameras and eyes. The proposed algorithm provides a realistic...

Adaptive coding of images via multiresolution ICA
Multiresolution (MR) representations have been very successful in image encoding, due to both their algorithmic performance and coding efficiency. However these transforms are ...
