چکیده

Les travaux présentés concernent la segmentation de zones hydriques par la méthode géométrique des contours actifs. Nous appliquons cette technique à des images radar et établissons un ensemble optimal de paramètres d’opération. Nos résultats montrent une délinéation précise des contours d’une zone hydrique à partir d’un simple pixel d’amorce. Nous montrons que la méthode est très stable par rapport au choix des paramètres ce qui en fait un bon candidat pour une implémentation automatique. In this work, we present segmentation of flooded area detection in spaceborne SAR images. We show that the geometric snakes method is robust to achieve the segmentation when applied to that kind of images. Our results show an exact segmentation of hydrous area edges from a single pixel seed. We show that the method is robust with respect to parameter values making it a good candidate for an automatic approach implementation.

Aerial and Satellite Image Segmentation Based on Shape- Constrained Geodesic Active Contours

In this paper, we propose a novel mathematical model to address segmentation from an aerial and satellite imagery. Segmentation is performed through the consistent recovery of the zero iso-surfaces of a level set function towards image’s foreground (desired object for extraction) and background discrimination. The level set method is embedded in a geodesic active contours variational formulatio...

SNAP: A Software Package for User-Guided Geodesic Snake Segmentation

We present a new software package for interactive segmentation of 3D images by geodesic snakes, with manual editing. Several variants of level set snakes are incorporated, including both gradientmagnitude based snakes as well as region-competition snakes. A complete segmentation pipeline, including image preprocessing, bubble initialization and parameter control, is provided in an intuitive use...

Detecting nets of linear structures in satellite images

Fast recent progresses in satellite imagery have made available high resolution images can be analyzed with computer vision techniques. A large part of civil engineering objects appear as linear structures (e.g. channels, roads, bridges etc.). In this paper, we present a technique to detect linear features in satellite images based on an improved version of the level set extrinsic curvature. It...

Comparing the Capability of Sentinel 2 and Landsat 8 Satellite Imagery in Land Use and Land Cover Mapping Using Pixel-based and Object-based Classification Methods

Introduction: Having accurate and up-to-date information on the status of land use and land cover change is a key point to protecting natural resources, sustainable agriculture management and urban development. Preparing the land cover and land use maps with traditional methods is usually time and cost consuming. Nowadays satellite imagery provides the possibility to prepare these maps in less ...

A Fast Level Set Method for Synthetic Aperture Radar Ocean Image Segmentation

Segmentation of high noise imagery like Synthetic Aperture Radar (SAR) images is still one of the most challenging tasks in image processing. While level set, a novel approach based on the analysis of the motion of an interface, can be used to address this challenge, the cell-based iterations may make the process of image segmentation remarkably slow, especially for large-size images. For this ...
