sar image segmentation and denoising simultaneously using level set methods
sar (synthetic aperture radar) image enhancement and segmentation is purpose of this thesis. sar image segmentation is a primary step before steps such as classification and target recognition. the main obstacle in sar image segmentation is inherent speckle noise. speckle noise is a multiplicative and highly destructive noise which results to intensity inhomogeneity. hence common segmentation m...
متن کاملWavelets for SAR Image Smoothing
Wavelets are an increasingly widely used tool in many applications of signal and image processing. This paper reviews the basic ideas of wavelets for representing the information in signals such as time series and images, and shows how wavelet shrinkage may be used to smooth these signals. This is illustrated by application to a synthetic aperture radar image. Some guidelines on using wavelet s...
متن کاملUnsupervised SAR Image Segmentation using Recursive Partitioning
We present a new approach to SAR image segmentation based on a Poisson approximation to the SAR amplitude image It has been established that SAR amplitude images are well approximated using Rayleigh distributions We show that with suitable modi cations we can model piecewise homogeneous regions such as tanks roads scrub etc within the SAR amplitude image using a Poisson model that bears a known...
متن کاملSAR Image Segmentation using Statistical Techniques
Segmentation is performed in recognition applications as a primary step towards extraction of interesting regions of an image. In this paper, the characteristic effects of Weibull and Fractal parameters in the segmentation of Synthetic Aperture Radar (SAR) and Optical images acquired from satellite platform is studied. The algorithms are tested for different window sizes and different number of...
متن کاملSAR Image Segmentation using Superpixel Merging Algorithm
Image segmentation is an important tool in satellite image processing and serves as an efficient front end to sophisticated algorithm and thereby simplify subsequent processing. It used to extract the meaningful objects lying in the image. The aim of the paper is to obtain the segmentation of the Synthetic Aperture Radar (SAR) image with minimum run time of the algorithm. The algorithm used for...
