Blind Source Parameters for Performance Evaluation of Despeckling Filters
The speckle noise is inherent to transthoracic echocardiographic images. A standard noise-free reference echocardiographic image does not exist. The evaluation of filters based on the traditional parameters such as peak signal-to-noise ratio, mean square error, and structural similarity index may not reflect the true filter performance on echocardiographic images. Therefore, the performance of ...
متن کاملUnassisted Quantitative Evaluation Of Despeckling Filters
SAR (Synthetic Aperture Radar) imaging plays a central role in Remote Sensing due to, among other important features, its ability to provide high-resolution, day-and-night and almost weather-independent images. SAR images are affected from a granular contamination, speckle, that can be described by a multiplicative model. Many despeckling techniques have been proposed in the literature, as well...
متن کاملPerformance of cumulant based inverse filters for blind deconvolution
Chi and Wu proposed a class of inverse filter criteria Jr;m using rth-order and mth-order cumulants (where r is even and m > r 2) for blind deconvolution (equalization) of a (nonminimum phase) linear time-invariant (LTI) system with only non-Gaussian measurements. The inverse filter criteria Jr;m for r = 2 are frequently used such as Wiggins’ criterion, Donoho’s criteria, and Tugnait’s inverse ...
متن کاملPerformance Comparison of Various Filters on Despeckling of Medical Ultrasound Imaging
Ultrasound Imaging plays vital role in diagnoses a disease. US image suffers from speckle noise. Despeckling is an important task for accurate diagnosis. In this paper experiment has been performed to measure the effectiveness of various filters available for despeckling. Results are compared qualitatively and quantitatively the Peak Signal to Noise Ratio and SSIM parameters are used to quantif...
متن کاملImproved expressions for performance parameters for complex filters.
Improved expressions are given for the performance parameters for transverse and axial gains for complex pupil filters. These expressions can be used to predict the behavior of filters that give a small axial shift in the focal intensity maximum and also predict the changes in gain for different observation planes.
