Multi-scale Segmentation of Venus Sar Images Using a Modified Watershed
نویسندگان
چکیده
ß We develop an application to identify and characterize polygonal features in SAR images, based on a watershed algorithm, modified for a good robustness to radar noise. ß Our system performs a multi-scale analysis of the image. Oversegmentation is prevented by a selection of outstanding contours; regions with less prominent contours are merged ß This analysis is applied to Venus images from the Magellan mission. The system makes the distinction between polygonal and nonpolygonal areas, and analyzes the polygons characteristics.

Identification of Polygonal Patterns on Venus Using Mathematical
Introduction: Many images in the Magellan SAR database show small (typically 1-3 km in diameter) polygonal features (fig. 1) on the surface of Venus [1][2], possibly related to climatic changes that occured in the past [2][3]. Although some of these regions have already been reported, we believe their abundance may be much higher. We developed a detection and recognition model to fully automati...
متن کاملA Novel Spot-Enhancement Anisotropic Diffusion Method for the Improvement of Segmentation in Two-dimensional Gel Electrophoresis Images, Based on the Watershed Transform Algorithm
Introduction Two-dimensional gel electrophoresis (2DGE) is a powerful technique in proteomics for protein separation. In this technique, spot segmentation is an essential stage, which can be challenging due to problems such as overlapping spots, streaks, artifacts and noise. Watershed transform is one of the common methods for image segmentation. Nevertheless, in 2DGE image segmentation, the no...
متن کاملA multi-scale convolutional neural network for automatic cloud and cloud shadow detection from Gaofen-1 images
The reconstruction of the information contaminated by cloud and cloud shadow is an important step in pre-processing of high-resolution satellite images. The cloud and cloud shadow automatic segmentation could be the first step in the process of reconstructing the information contaminated by cloud and cloud shadow. This stage is a remarkable challenge due to the relatively inefficient performanc...
متن کاملSAR image segmentation using Color space clustering and Watersheds
SAR images data are the result of a coherent imaging system that produces the speckle noise phenomenon. Image segmentation is the process of separating or grouping an image into different parts. The good performance of recognition algorithms depend on the quality of segmented image. An important problem in SAR image application is correct segmentation. In this paper, we consider the problem of ...
متن کاملWatershed identification of polygonal patterns in noisy SAR images
This paper describes a new approach to pattern recognition in synthetic aperture radar (SAR) images. A visual analysis of the images provided by NASA's Magellan mission to Venus has revealed a number of zones showing polygonal-shaped faults on the surface of the planet. The goal of the paper is to provide a method to automate the identification of such zones. The high level of noise in SAR imag...
