Recent Trends in 2D Blind Deconvolution for Nondestructive Evaluation

چکیده
Ultrasonic imaging for nondestructive evaluation (NDE) applications is an important process for industrial applications. Understanding the material structure is an integral part of the manufacturing as well as maintenance operations. Especially for the critical industries like airlines where each component of the aircraft is required to perform at its best. One way to analyze material samples for defects is to take its x-ray image. This method is not only hazardous but also highly impractical to be used in many industrial applications specially during running conditions of structures. In addition, it is also very costly procedure. Ultrasonic imaging is an alternate for such application and is constantly gaining popularity in the industrial applications. Ultrasonic images are constrained by the sensor positions and indirect image formation. In this paper, some recent techniques in the areas of ultrasonic image enhancement and restoration, developed by the authors, are presented. Three new approaches have been presented to enhance the ultrasonic images with minimum or no information of the distortion function or the imaging system characteristics.

Wavelet-based deconvolution of ultrasonic signals in nondestructive evaluation
In this paper, the inverse problem of reconstructing reflectivity function of a medium is examined within a blind deconvolution framework. The ultrasound pulse is estimated using higher-order statistics, and Wiener filter is used to obtain the ultrasonic reflectivity function through wavelet-based models. A new approach to the parameter estimation of the inverse filtering step is proposed in th...

Abstract: Image restoration is a critical step in many vision applications. Due to the poor quality of Passive Millimeter Wave (PMMW) images, especially in marine and underwater environment, developing strong algorithms for the restoration of these images is of primary importance. In addition, little information about image degradation process, which is referred to as Point Spread Function (PSF...
متن کاملSparsity enhancement for blind deconvolution of ultrasonic signals in nondestructive testing application.
The received signal in ultrasonic pulse-echo inspection can be modeled as a convolution between an impulse response and the reflection sequence, which is the impulse characteristic of the inspected object. Deconvolution aims at approximately inverting this process to improve the time resolution so that the overlap between echoes from closely spaced reflectors becomes small. This paper presents ...
متن کاملDeconvolution of ultrasonic nondestructive evaluation signals using higher-order statistics
In ultrasonic nondestructive evaluation (NDE) of materials, pulse echo measurements are masked by the characteristics of the measuring instruments, the propagation paths taken by the ultrasonic pulses, and are corrupted by additive noise. Deconvolution operation seeks to undo these masking effects and extract the defect impulse response which is essential for identification. In this contributio...

In this paper we introduce a multichannel blind deconvolution algorithm for the restoration of two-dimensional (2D) seismic data. This algorithm is based on a 2D reflectivity prior model, which takes into account the spatial dependency between neighboring traces. Each reflectivity column is estimated from the corresponding observed trace using the estimate of the preceding reflectivity column a...
