Wavelet Packets Best Tree 4 Points Encoded (BTE) Features
نویسنده
چکیده
The research aimed to introduce newly designed features for speech signal. The newly developed features are designed to normalize the dynamic structure of best tree decomposition of wavelet packets. The 4 points encoded vector is a full of information just like the original best tree’s structure. It is a loss less encoding system that grantees 100% reconstruction of the original best tree. The encoding process for BTE features vector is developed as such to minimize the distance based on frequency adjacency. The implied scoring system makes BTE suitable for recognition problems.

Voiced/Unvoiced and Silent Classification Using HMM Classifier based on Wavelet Packets BTE features
Wavelet Packets Best Tree Encoded (BTE) features is used here as base features for HMM classifier. The research aimed to introduce the newly designed features that are discussed in [1]. The considered problem is Voiced, Unvoiced and Silent classification. Comparison to the 19 filter banks features is provided. Although it is simple and straight forward, BTE makes comparable results to the 19 el...
متن کاملJoint Wavelet Packets for Groups of Frames in MCTF
Wavelet packets provide a flexible representation of data, which has been proved to be very useful in a lot of applications in signal, image and video processing. In particular, in image and video coding, their ability to best capture the input content features can be exploited by designing appropriate optimization criteria. In this paper, we introduce joint wavelet packets for groups of frames...
متن کاملOptimal bit allocation and best-basis selection for wavelet packets and TSVQ
To use wavelet packets for lossy data compression, the following issues must be addressed: quantization of the wavelet subbands, allocation of bits to each subband, and best-basis selection. We present an algorithm for wavelet packets that systematically identifies all bit allocations/best-basis selections on the lower convex hull of the rate-distortion curve. We demonstrate the algorithm on tr...

متن کاملAnisotropic 2-D Wavelet Packets and Rectangular Tiling: Theory and Algorithms
We propose a new subspace decomposition scheme called anisotropic wavelet packets which broadens the existing definition of 2-D wavelet packets. By allowing arbitrary order of row and column decompositions, this scheme fully considers the adaptivity, which helps find the best bases to represent an image. We also show that the number of candidate tree structures in the anisotropic case is much l...
