COMPARISON OF FILTERS DEDICATED TO SPECKLE SUPPRESSION IN SAR IMAGES
SAR Images Radar Images Filtering Mathematical Morphology Speckle Suppression
2016/11/23
This paper presents the results of research on the effectiveness of different filtering methods dedicated to speckle suppression in SAR images. The tests were performed on RadarSat-2 images and on an ...
A METHOD FOR SAR SPECKLE REDUCTION BASED ON PARTIAL DIFFERENTIAL EQUATION
Image processing Filtering Digital photogrammetry Feature detection Geography
2015/12/31
Synthetic Aperture Radar (SAR) has been get broad recognition and application in many domains such as surveying and mapping.But the SAR speckles influence the interpretation of the image badly. In thi...
THE EFFECT OF SPECKLE REDUCTION ON COHERENCE ESTIMATION AND INTERFEROMETRIC PHASE OF INSAR
SPECKLE REDUCTION COHERENCE ESTIMATION INTERFEROMETRIC PHASE OF INSAR
2015/12/30
Synthetic aperture radar (SAR) images always suffer from strongly speckle noise, which is a great obstacle to coherence (or correlation coefficient) estimation and interferometric phase, furthermore h...
Speckle Denoising Based on Bivariate Shrinkage Functions and Dual-Tree Complex Wavelet Transform
Transformation Algorithms SAR Radiometric Processing, Image
2015/11/20
Bivariate shrinkage functions (bsf) statistically denoted as joint probability density functions (pdf) and noise pdf, can be united by MAP to denoise image. Because the intensity of speckle in synthet...
THE CONTRAST RESEARCH OF THE METHODS OF RESTRAINING THE SPECKLE NOISE OF SAR IMAGES
SAR High resolution Method Analysis Model
2015/6/1
There commonly exists speckle noise in the SAR images. It badly disturbs the extraction and interpretation of the information of the objects, influences the application of the SAR images. So it has im...
A SAR SPECKLE FILTERING ALGORITHM TOWARDS EDGE SHARPENING
Radar Speckle Reduction Texture Image Processing
2014/12/29
One of the major difficulties when classifying synthetic aperture radar (SAR) images is the existence of speckle due to coherent processing. Existing speckle filtering algorithms can effectively reduc...
