Automatic thresholding for edge detection in sar imagery
SAR Imagery Edge Detection Thresholding Ratio of Averages
2015/8/20
A few edge detectors are derived from the contrast ratio edge detector to extract linear features from SAR imagery with a constant
probability of false alarm. But all of these detectors need one or m...
Noise Filtering of Remotely Sensed Images using Iterative Thresholding of Wavelet and Curvelet Transforms
Multi-resolution analysis wavelet transform curvelet transform additive noise noise filtering fixed thresholding iterative thresholding
2014/12/4
This article presents techniques for noise filtering of remotely sensed images based on Multi-resolution Analysis (MRA). Multiresolution techniques provide a coarse-to-fine and scale-invariant decompo...
AN ALGORITHM FOR THRESHOLDING IN THE CONTEXT OF SIGNAL DENOISING WITH WAVELETS
signal processing analysis denoising filtering
2010/1/11
The problem of estimating a signal corrupted by additive noise has been of
interest to many researchers for practical as well as theoretical reasons. Wavelet based
methods have become increasingly p...
Thresholding Technique with Adaptive Window Selection for Uneven Lighting Image
Image segmentation Thresholding Adaptive window selection
2010/12/15
By adaptively selecting image window size based on the pyramid data structure manipulation of Lorentz information measure, a new technique for image thresholding is proposed. The advantage of this tec...
Fuzzy clustering with spatial constraints for image thresholding
