We have proposed new approach for the speech recognition system by applying kernel adaptive filter for speech enhancement and for the recognition, the hybrid HMM/DTW methods are used in this paper. Noise removal is very important in many applications like telephone conversation, speech recognition, etc. In the recent past, the kernel methods are showing good results for speech processing applic...

This paper describes the signature as a one of the most robust and widely used trait in biometric verification. The signature is also known as behavioral biometric property. We present comparative analysis of offline signature recognition based on Dynamic Time Warping (DTW) and Maximally Stable Extremely Regions (MSER). The MSER system reported accuracy of 95. 371% where FAR is 5. 25% and FRR i...

Fine metallic screens are important sub-systems in propellant tank systems of spacecrafts due to their application as filter devices. The flow resistance has to be known for a proper design of tank and feed line systems. In this paper the flow resistance of application-relevant metallic screens is investigated experimentally. The weave types “dutch twilled weave” (DTW) and “broad mesh” (BM) wer...

This paper describes the implementation of two isolated digit recognition techniques and is a comparison between the algorithms implemented. Any digit recognition comprises of mainly two stages feature extraction and similarity evaluation. Here, two feature extraction techniques, namely linear predictive cepstral coefficients (LPCC) and mel frequency cepstral coefficients (MFCC) are implemented...

This paper briefly describes the systems presented by the Software Technologies Working Group (http://gtts.ehu.es, GTTS) of the University of the Basque Country (UPV/EHU) to the Spoken Web Search (SWS) task at MediaEval 2013. GTTS systems consist of four main modules: (1) feature extraction; (2) speech activity detection; (3) DTW-based query matching; and (4) score calibration and fusion. The m...

Speaker verification from talking a few words of sentences has many applications. Many methods as DTW, HMM, VQ and MQ can be used for speaker verification. We applied MQ for its precise, reliable and robust performance with computational simplicity. We also used pitch frequency and log gain contour for further improvement of the system performance.

an improved method to detect the critical points and obtain a matching path in 1 on-line signature verification. More critical points will be detected and the will be improved by the proposed method. We first detect critical points by ature curves for extremum points. We then introduce an improved DTW nal backward-merging DTW (BBMDTW), for the flexible matching of two 1D inally, the critical po...

In recent years Dynamic Time Warping (DTW) has emerged as the distance measure of choice for virtually all time series data mining applications. For example, virtually all applications that process data from wearable devices use DTW as a core sub-routine. This is the result of significant progress in improving DTW’s efficiency, together with multiple empirical studies showing that DTW-based cla...

Mining sequential data is an old topic that has been revived in the last decade, due to the increasing availability of sequential datasets. Most works in this field are centred on the definition and use of a distance (or, at least, a similarity measure) between sequences of elements. A measure called Dynamic Time Warping (DTW) seems to be currently the most relevant for a large panel of applica...

Satellite Image Time Series (SITS) record the continuous temporal behavior of land cover types and thus provide a new perspective for finer-grained classification compared with usual spectral spatial information contained in static image. In addition, SITS data is becoming more accessible recent years due to newly launched satellites accumulated historical data. However, lack labeled training s...
