Traditional image segmentation methods working with low level image features are usually difficult to adapt to higher level tasks, such as object recognition and scene understanding. Object segmentation emerges as a new ...

In this paper we present a new block adaptive coding scheme which uses non-rectangular Laplacian Pyramid Algorithms. The proposed method JB adapted to the local image contents. The original image is broken into subimages ...

This paper presents an absolute capacitive angular-position sensor with a contactless rotor. The sensor is mainly composed of three parts: the capacitive sensing element, a signal processor, and a microcontroller. The ...

This paper deals with the blind source separation. The task consists in separating some independent and linearly mixed signals called sources. After some general remarks, the model is recalled and our approach based on the ...

Cloud Modulation (CM) is a novel transmission method that mitigates the non-linear impairments introduced by the Radio-over-Fiber (RoF) links of a distributed antenna system. In CM, constant-envelope phase-modulated radio ...

This work develops a novel dynamic fuzzy logic system that, based on a fuzzy basis function expansion, successfully solves the non-linear problem of narrowband interference prediction and rejection in DS-SS. A fuzzy basis ...

Rectangular sampling lattices bave been extensively applied to image coding. Sampling is a fundamental orera.tion m image coding systems as a proper selection of the sampling lattice minimizes the physica support of the ...

In the frame of an SMOS follow-on operational mission, a new instrument design is being developed based on the lessons learned from MIRAS, the SMOS payload. To reduce hardware complexity and mass, digital In-phase Quadrature ...

A new linear feature detector for synthetic aperture radar (SAR) images is presented in this article by embedding a three-region filter into the wedgelet analysis framework. One of its main features is that it can detect ...
