Speckle Noise Reduction in Ultrasound Images using IWD

چکیده
This paper implements Intelligent Water Drop (IWD) technique for removal of speckle noise from the ultrasound images. Noise is a factor that degrades the quality of images, so we need to use an efficient technique to remove the noise from the images. IWD algorithm removes the noise and also retains the useful information of the medical image. It improves the quality of an image. In this work, removal of speckle noise has been tested on 5 ultrasound images by using IWD technique. Moreover IWD technique has been compared with the median filter and wavelet denoising methods on the basis of the parameters namely Peak Signal to Noise Ratio (PSNR), Structural Similarity Index for Measuring image quality (SSIM), Coefficient of correlation (Coc) and Edge Preservation Index (EPI). The results show that the IWD technique is better than wavelet denoising and median filter for removal of speckle noise as well as edge preservation

Speckle is a granular noise-like phenomenon which appears in Synthetic Aperture Radar (SAR) images due to coherent properties of SAR systems. The presence of speckle complicates both human and automatic analysis of SAR images. As a result, speckle reduction is an important preprocessing step for many SAR remote sensing applications. Speckle reduction can be made through multi-looking during the...

Speckle is a multiplicative noise that degrades ultrasound images. In this paper, a statistical spatially adaptive approach for speckle reduction in medical ultrasound images based posterior conditional means (PCM) estimation in the nonsubsampled contourlet domain is proposed. In this framework, a new class of statistical model for nonsubsampled contourlet coefficients is proposed. And the prop...

Synthetic Aperture Radar (SAR) images are inherently affected by a multiplicative noise-like phenomenon called speckle, which is indeed the nature of all coherent systems. Speckle decreases the performance of almost all the information extraction methods such as classification, segmentation, and change detection, therefore speckle must be suppressed. Despeckling can be applied by the multilooki...
