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
