Wavelet filtering of SAR images based on non-Gaussian assumptions
Radar images are affected by a multiplicative noise depending on the underlying signal (the ground reflectivity) due to the coherence of the radar wavelength. Images present a strong pixel to pixel variability considerably reducing the efficiency of target detection and classification algorithms. We propose in this study filtering this noise using image multiresolution analysis. The value of th...
متن کاملWavelet-based SAR image enhancement and speckle reduction for classification
Denoising and image enhancement pre-processing techniques are fundamental for segmentation and classification purposes in a wide range of applications. Particularly, in the field of remote sensing, where synthetic aperture radar, (SAR) images are characterized by the intrinsic multiplicative noise, so-called speckle which affects negatively image analysis techniques, such as automatic target re...
متن کاملWavelet Speckle Reduction for Sar Imagery Based on Edge Detection
This paper introduces a wavelet transform speckle reduction algorithm for Synthetic Aperture Radar (SAR) imagery based on edge detection. Existing speckle algorithm can efficiently reduce the speckle effect but unfortunately also, to some degree, smear edges and blur images. In this paper, the original image is firstly logarithmic transformed and decomposed with multi-scale wavelet transform. F...
متن کاملNon-local Means Filter for Polarimetric Sar Speckle Reduction -experiments Using Terrasar-x Data
The speckle is omnipresent in synthetic aperture radar (SAR) images as an intrinsic characteristic. However, it is unwanted in certain applications. Therefore, intelligent filters for speckle reduction are of great importance. It has been demonstrated in several literatures that the non-local means filter can reduce noise while preserving details. This paper discusses non-local means filter for...
متن کاملSpeckle Noise Reduction in Ultrasound Images by Wavelet Thresholding
Medical practitioners are increasingly using digital images during disease diagnosis several state-of-the-art medical equipments are producing images of different organs, which are used during various stages of analysis. Examples of such devices include MRI, CT, ultrasound and X-Ray. In medical image processing, image denoising has become a very essential exercise all through the diagnose becau...
