Advanced Defect Detection Algorithm Using Clustering in Ultrasonic NDE
A range of materials used in industry exhibit scattering properties which limits ultrasonic NDE. Many algorithms have been proposed to enhance defect detection ability, such as the well-known Split Spectrum Processing (SSP) technique. Scattering noise usually cannot be fully removed and the remaining noise can be easily confused with real feature signals, hence becoming artefacts during the ima...
متن کاملDefect Detection Using Quiescent Signal Analysis
IDDQ or steady state current testing has been extensively used in the industry as a mainstream defect detection and reliability screen. The background leakage current has increased significantly with the advent of ultra deep submicron technologies. This increased background leakage noise makes it difficult to differentiate defect-free devices from those with defects that draw significantly smal...
متن کاملBayesian Harmonic Models for Musical Signal Analysis
This paper is concerned with the Bayesian analysis of musical signals. The ultimate aim is to use Bayesian hierarchical structures in order to infer quantities at the highest level, including such things as musical pitch, dynamics, timbre, instrument identity, etc. Analysis of real musical signals is complicated by many things, including the presence of transient sounds, noises and the complex ...
متن کاملUltrasonic Nde Image Enhancement with Nonlinear Filters in Signal Subspaces
The objective of this study to examine an effective method to remove speckles for enhancing ultrasonic NDE images. The new method presented is based on Independent Component Analysis (ICA). Firstly, in terms of the characteristic of NDE images, we believe that the main image features in NDE images are constructed by “edges”, thus we use “Edge Basis Model” to describe their basis images and prop...
متن کاملAutomatic hard thresholding for sparse signal reconstruction from NDE measurements
We propose an automatic hard thresholding (AHT) method for sparse-signal reconstruction. The measurements follow an underdetermined linear model, where the regression-coefficient vector is modeled as a superposition of an unknown deterministic sparse-signal component and a zero-mean white Gaussian component with unknown variance. Our method demands no prior knowledge about signal sparsity. Our ...
