Robust speckle reducing anisotropic diffusion

EUSAR 2012; 9th European Conference on Synthetic Aperture Radar, 2012

Speckle Filter performance strongly depends on speckle model and heterogeneity measurement. Classical single-stage speckle filters fails to retain image structures on iteration, but iteration is necessary for effective smoothing of speckle. In this paper we propose a heterogeneity measuring technique that enables to apply traditional filters iteratively. We also propose a new robust anisotropic diffusion (AD) based speckle filter (ROSRAD), ...


A clustering approach for change detection in SAR images

EUSAR 2012; 9th European Conference on Synthetic Aperture Radar, 2012

This paper presents a new approach for change detection in SAR images based on clustering method. Classic change detection methods use a hard threshold to divide the difference map into two classes: change and unchanged, which has a disadvantage that some weak changed regions are often undetected. Unlike those methods, our proposed method use expectation maximization with graph cut optimization ...

  • Robust speckle reducing anisotropic diffusion

    Speckle Filter performance strongly depends on speckle model and heterogeneity measurement. Classical single-stage speckle filters fails to retain image structures on iteration, but iteration is necessary for effective smoothing of speckle. In this paper we propose a heterogeneity measuring technique that enables to apply traditional filters iteratively. We also propose a new robust anisotropic diffusion (AD) based speckle filter (ROSRAD), that shown to perform better than the existing speckle reducing AD filters like SRAD and DPAD. Performance of ROSRAD is tested on simulated and real SAR images and compared with other AD filters.

  • A clustering approach for change detection in SAR images

    This paper presents a new approach for change detection in SAR images based on clustering method. Classic change detection methods use a hard threshold to divide the difference map into two classes: change and unchanged, which has a disadvantage that some weak changed regions are often undetected. Unlike those methods, our proposed method use expectation maximization with graph cut optimization to cluster the difference map into three classes: strong changed areas, weak changed areas and unchanged areas. The experimental results on real SAR images show that our approach obtains a higher detection rate than the previous ones.

  • Phase coherence factor with sub-aperture beamforming

    High-frame-rate echocardiography using unfocused transmit beams and parallel receive beamforming is a promising method for evaluation of cardiac function, such as imaging of rapid propagation of the heart wall vibration. In this technique, high temporal resolution is realized at the expense of spatial resolution and contrast. The phase coherence factor has been developed to improve spatial resolution and contrast in ultrasonography. It evaluates the variance in phases of echo signals received by individual transducer elements after delay compensation as in the conventional delay and sum beamforming process. However, the phase coherence factor suppresses speckle echoes because phases of speckle echoes fluctuate due to their mutual interference. In the present study, total receiving aperture was divided into several sub- apertures, and conventional delay and sum beamforming was performed with respect to each sub-aperture to suppress echoes from scatterers except for that from a focal point. After sub-aperture beamforming, the phase coherence factor was obtained from beamformed RF signals from respective sub-apertures. By means of this procedure, undesirable echoes, which can interfere with the echo from a focal point, can be suppressed by sub-aperture beamforming, and the degradation of the phase coherence factor due to phase fluctuation caused by such interference can be avoided. Effects of sub-aperture beamforming were evaluated using a phantom. By sub-aperture beamforming, the average intensity of speckle echoes from a diffuse scattering medium was significantly higher (-39.9 dB) than that obtained without sub-aperture beamforming (-48.7 dB). As for spatial resolution, the width at half maximum of the lateral echo amplitude profile obtained without the phase coherence factor was 1.06 mm. Using the phase coherence factor, spatial resolution was improved significantly, and sub-aperture beamforming achieved a better spatial resolution of 0.75 mm than that of 0.78 mm obtained without sub-aperture beamforming. Using sub-aperture beamforming in estimation of coherence factor, better visualization of speckle echoes and spatial resolution could be realized simultaneously by suppressing out-of-focus echoes.

  • A quarter-wave phase-stepping algorithm for fiber-optic electronic speckle pattern interferometry using zero-crossing triggers

    An efficient phase-stepping method for the use in fiber-optic electronic speckle pattern interferometry is proposed. A fiber-optic Michelson interferometer is phase-modulated, and the zero-crossing points of a back- reflected interference signal, that have consecutive pi phase difference, are used to trigger the charged-coupled device camera to capture specklegrams with pi/2 phase difference. A phase error of less than 3 mrad with 100-Hz image capture speed has been obtained in an open-loop configuration. Also, it has been experimentally shown that the phase-stepping accuracy of the proposing method does not depend on the nonlinear actions of the phase modulator

  • Fast least-squares phase estimation in speckle imaging

    This paper describes a fast direct algorithm for obtaining least-squares phase estimates from arrays of noisy phase differences. The algorithm uses the fast Fourier transform (FFT) to diagonalize and decouple the system of equations which results from the application of the least-squares criterion. It is accurate and stable, and is perhaps an order of magnitude faster than the best iterative method. The effectiveness of the algorithm has been demonstrated by using it in connection with the Knox-Thompson speckle-imaging procedure to restore an optical object perturbed by simulated atmospheric turbulence.

  • Parameter estimation of K distribution based on second-kind statistics

    The parameters of K distribution are estimated in this paper, and the log- cumulant estimator is proposed based on second-kind statistics. The performance of the log-cumulant estimator is tested on the Monte Carlo simulations. Parameter estimation results demonstrate that the log-cumulant estimator leads to high estimation accuracy for the small values of the shape parameter.

  • Speckle suppression by adaptive nonlinear filtering

    Using a good statistical model of speckle formation is important for designing an adaptive filter for speckle reduction in ultrasound B-scan images. Most clinical ultrasound imaging systems use nonlinear logarithmic functions to reduce the dynamic range of the input echo signal and emphasize objects with weak back scatter. The statistics of log-compressed images for the Nakagami distribution are used for designing an adaptive nonlinear filter for the purpose of speckle reduction. We processed two original ultrasound images of kidney and liver to demonstrate the efficiency of the designed filter.
