An Analysis of 2D Bi-Orthogonal Wavelet Transform Based On Fixed Point Approximation
نویسندگان
چکیده
As the world advances with technology and research, images are being widely used in many fields such as biometrics, remote sensing, reconstruction etc. This tremendous growth in image processing applications, demands majorly for low power consumption, low cost and small chip area. In this paper we analyzed 2D biorthogonal wavelet transform based on Fixed point approximation. Filter coefficients of the bi-orthogonal wavelet filters are quantized before implementation. The efficiency of the results is measured for some standard gray scale images by comparing the original input images and the reconstructed images. SNR and PSNR value shows that this implementation is performed effectively without any loss in image quality. Key Words— Bi-orthogonal wavelet Transform, Fixed Point Approximation

Comparative Analysis of Wavelet-based Feature Extraction for Intramuscular EMG Signal Decomposition
Background: Electromyographic (EMG) signal decomposition is the process by which an EMG signal is decomposed into its constituent motor unit potential trains (MUPTs). A major step in EMG decomposition is feature extraction in which each detected motor unit potential (MUP) is represented by a feature vector. As with any other pattern recognition system, feature extraction has a significant impac...
متن کاملAn Efficient Architecture for a Lifted 2D Biorthogonal DWT
This paper presents a new algorithm for a 2D non-separable lifted bi-orthogonal wavelet transform. The algorithm is derived by factoring complementary pairs of wavelet transform 2D filters. The results are efficient architectures for real time signal processing, which do not require transpose memory for the 2D processing of data. The proposed architecture exploits in place implementation, inher...
متن کاملOrthogonal Wavelet Coefficient Precision and Fixed Point Representation
The Discrete Wavelet Transform (DWT) is an important transform with many signal processing applications, most notably, compression. Many architectures have been proposed to perform DWT, but few address the precision of the coefficients necessary to ensure perfect reconstruction. The goal of this work is to experimentally determine the precision of the filter coefficients (for an orthogonal wave...
متن کاملOn Exploiting Wavelet Bases in Statistical Region-based Segmentation
Statistical region-based segmentation methods such as the Active Appearance Models establish dense correspondences by modelling variation of shape and pixel intensities in low-resolution 2D images. Unfortunately, for high-resolution 2D and 3D images, this approach is rendered infeasible due to excessive storage and computational requirements. This paper addresses the problem by modelling the ap...
