Harmonic Detection Algorithm based on DQ Axis5
The paper presents the DQ axis with Fourier analysis (DQF) algorithm to identify harmonic quantities for hybrid power filters. This algorithm is a combination of the advantages of DQ axis method and sliding window Fourier analysis (SWFA). This paper also presents the harmonic elimination by using the DQF algorithm for both three-phase balanced and unbalanced systems. The results show that the u...
متن کاملA New Algorithm for Voice Activity Detection Based on Wavelet Packets (RESEARCH NOTE)
Speech constitutes much of the communicated information; most other perceived audio signals do not carry nearly as much information. Indeed, much of the non-speech signals maybe classified as ‘noise’ in human communication. The process of separating conversational speech and noise is termed voice activity detection (VAD). This paper describes a new approach to VAD which is based on the Wavelet ...
متن کاملResearch on Color Watermarking Algorithm Based on RDWT-SVD
In this paper, a color image watermarking algorithm based on Redundant Discrete Wavelet Transform (RDWT) and Singular Value Decomposition (SVD) is proposed. The new algorithm selects blue component of a color image to carry the watermark information since the Human Visual System (HVS) is least sensitive to it. To increase the robustness especially towards affine attacks, RDWT is adopted for its...
متن کاملResearch on the Fabric Defect Detection Method based on Improved PSO and NN Algorithm
This paper can reasonably identify the connection weight and threshold of NN and improve capability of true problem solution. This paper also applies PSO-BP NN model into classification of fabric flaws, decomposes the fabric image at single layer and extract the sub-image in horizontal and vertical direction to represent longitudinal and latitudinal texture by using orthogonal wavelet transform...
متن کاملResearch on Cerebral Aneurysm Detection Based on OPTA Algorithm
It is the key step of the cerebral aneurysm recognition system to locate the cerebral aneurysm accurately and fast onto the image. A new detection method of cerebral aneurysm, which is based on the improved thinning algorithm, is proposed after analyzing the morphological characteristics of cerebral aneurysm fully in the paper. In this new detection method, the improved OPTA algorithm is used t...
