Multi-resolution methods applied to active contour models can speed up processes and
improve results. In order to estimate those improvements, we describe and compare in this …

In this paper, it is tried to establish a relationship between Munsell soil colour and
normalized difference vegetation index (NDVI) using National Oceanic and Atmospheric …

This paper addresses the issue of motion estimation on image sequences. The standard
motion equation used to complete the apparent motion of image irradiance patterns is an …

This paper describes an innovative approach to estimate motion from image observations of
divergence-free flows. Unlike most state-of-the-art methods, which only minimize the …

Our principal motivation is to study time sequences of echocardiographic raw data to track
specific anatomical structures. First, we show that the image processing can make direct use …

In this paper we define a complete framework for processing large image sequences for a
global monitoring of short range oceanographic and atmospheric processes. This framework …

Data Assimilation is a mathematical framework used in environmental sciences to improve
forecasts performed by meteorological, oceanographic or air quality simulation models. It …

In this article we propose a new method to estimate ocean mesoscale structures of the surface
current velocity by processing sea surface satellite images. Assuming that the intensity …

We present in this paper a motion computation and interpretation framework for oceanographic
satellite images. This framework is based on the use of a non quadratic regularization …

Fires caused by natural or technological disasters emit large amounts of smoke which, once
formed into plumes, may affect the human health and the environment. Satellite remote …
