It is well known that in reverberant environments, the human auditory system has the ability to pre-process reverberant signals to compensate for reflections and obtain effective cues for improved recognition. In this study, we propose such a preprocessing technique for combined detection and enhancement of speech using a single microphone in reverberant environments for distant speech applicat...

Generalized Lapped Orthogonal Transform (GenLOT) based image coder is used to compress 2-D seismic data sets. Its performance is compared to the results using wavelet-based image coder. Both algorithms use the same state-ofthe-art zerotree coding for consistency and fair comparison. Several parameters such as lter length and objective cost function are varied to nd the best suited lter banks. I...

In this paper we present algorithms for the automatic timesynchronization of score-, MIDIor PCM-data streams which represent the same polyphonic piano piece. In contrast to related approaches, we compute the actual alignment by using note parameters such as onset times and pitches. Working in a score-like domain has advantages in view of the efficiency and accuracy: due to the expressiveness of...

Abstract – In parallel processing of digital signals, we require an algorithm which can be “parallelized” to take advantage of multiple processing units or a signal decomposition whereby each component in the signal decomposition can be processed in parallel. The filter bank is introduced as one way to provide a signal decomposition useful in parallel signal processing. In this paper, we review...

Present information processing suffers from the lack of coordination among researches on new methods of solving information processing problems and non-interoperability of information processing systems. This thesis suggests a unified web-based bank of knowledge meant for coordinating researches on the new methods, supporting development of interoperable intelligent information-processing syste...
