Beamformer design exploiting blind source extraction techniques

Brian Bloemendal, Jakob van de Laar, Piet Sommen
2012 2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)  
Recently we have shown how a blind source extraction (BSE) algorithm can be equipped with some prior information about mixing parameters of the desired source in order to extract this source.  ...  In the context of blind beamforming especially the work in [4] is interesting since it exploits prior information about the mixing parameters of the desired source.  ...  With traditional beamforming techniques it is then only possible to use these three sensors to build a beamformer from the parameterized model.  ...

Blind watermarking technique for topographic map data

Haowen Yan, Jonathan Li
2011 Applied Geomatics  
A blind watermarking technique for protecting topographic data from illegal use is proposed, taking into account four rules, i.e., usability, invisibility, robustness, and blindness.  ...  Our experiments show that the technique can resist the attacks from data format change, random noise, similarity transformation, and data editing to some extent.  ...  However, none of such algorithms are blind in detection process.  ...
