A cost-effective method for ultrasound volumetric imaging
(1996)
A synthetic receive aperture technique is explored for cost-effective ultrasound scanners with high frame rates and beam density. The technique provides ultrasound volumetric imaging where beam count is very large with 2-D ...
Segmentation of ultrasonic images using fuzzy sets
(1996)
An image segmentation technique based on fuzzy sets for ultrasonic B-scans is presented. The fuzzy c-means algorithm is adapted to B-scan images. The classes constituting a region are obtained through fuzzy partitioning ...
Analytical solution for continuous-time Kalman tracking filters with colored measurement noise in frequency domain
(Ieee-Inst Electrical Electronics Engineers Inc, 1994)
New expressions are given for analytical solutions to the steady-state Kalman gains of the two-state exponentially correlated velocity (ECV) and the three-state exponentially correlated acceleration (ECA) tracking filters ...
A fuzzy colour quantizer for renderers
(Elsevier Science Bv, 1998)
This paper presents a new colour quantization method for ray tracing. Normally, quantization is carried out by generating statistics about the colours present in the original image. Then a colour look-up table is created ...
Correlation analysis of ultrasonic speckle for motion estimation

Beam space processing for low-cost scanners
(I E E E, 1996)
A subaperture processing technique suitable for low-cost ultrasound imaging systems is presented. The technique is based on multi-element synthetic aperture approach and beam interpolation. A large receive aperture is ...
A noise reduction algorithm in ECG signals using wavelet transform
(Ieee, 1998)
A noise reduction algorithm based on multiresolution orthogonal wavelet transform in ECG signals is discussed. The results are presented for different analysis and synthesis filter coefficients proposed by Vetterli-Herley ...
Improving performance of switched reluctance motor by fuzzy logic controller
(John Wiley & Sons Ltd, 1999)
This paper presents torque ripple minimization of a switched reluctance motor (SRM) by using a fuzzy controller, The nonlinear model of the SRM and the mathematical model of the converter circuit are driven. The motor used ...
