Smoothing of Ultrasound Images with the p-lag FIR Structures
نویسندگان
چکیده
An analysis is given of the specific points of the noise power gain of the p-lag median hybrid FIR filters in applications to ultrasound image processing. An important feature of such a gain is that, at some cross points, it converges to the reduced degree one. The effect of smoothing is evaluated in terms of the signal-to-noise ratio and root mean square error metrics. We show that image enhancing has the best appearance if the FIR smoother degree and p are both optimized. Key-Words: FIR smoothing, Ultrasound, Hybrid median structure, Power gain.

An Analysis of Hybrid FIR Structures in Applications to Ultrasound Image Processing
In this paper, we analyze and develop hybrid finite impulse response (FIR) structures in applications to image enhancing. Three particular hybrid structures are observed: the FIR median hybrid (FMH), the moving average hybrid (MAH), and the smoothing FIR hybrid (FSH). All these structures have been developed for preserving a sharp edge and enhancing ultrasound images. It is shown that, among ot...

Abstract: A smoothing finite impulse response (FIR) filter is addressed for discrete time-invariant state-space polynomial models commonly used to represent signals over finite data. A general gain is derived for the relevant p-lag unbiased smoothing FIR filter. Applications are given for the time interval errors of a local crystal clock and the United States Naval Observatory Master Clock. An ...

متن کاملL2 signal reconstruction with FIR and steady-state behavior constraints
The problem of recovering an analog signal from discrete measurements, known as signal reconstruction, can be formulated as a sampled-data L fixed-lag smoothing problem. In this paper the problem is solved under the constraint that the reconstructor is an FIR (finite impulse response) system. An analytic and numerically stable solution, whose computational complexity is linear in the length of ...
