Et Aveugles En Traitement Du Signal Et Des Images

We consider the problem of subspace estimation in aBayesian setting. Since we are operating in the Grassmann man-ifold, the usual approach which consists of minimizing the meansquare error (MSE) between the true subspace and its estimatemay not be adequate as the MSE is not the natural metric in theGrassmann manifold , i.e., the set of -dimensional subspacesin . As an al...

Traitement des images et radiothérapie Image processing and radiotherapy

Medical images are of great importance in radiotherapy, which became a privileged application field for image processing techniques. Moreover, because of the progression of the computers’ performances, these techniques are also in full expansion. Today, the recent developments of the radiotherapy (3DCR, IMRT) offer a huge place to them. Effectively, they can potentially answer to the precision ...

Extraction et analyse de l'impact émotionnel des images

This paper proposes a method to extract the emotional impact of images. Emotions are often associated with facial expressions, but we decided not to consider this feature as first emotional characteristic of natural images, which, in general, does not contain faces. Using this statement, our tests have been done on a new image database composed of low semantic diversified images. The complexity...

Utilisation des quasi-invariants géométriques pour l’appariement et la modélisation des images de segments de droite

Image matching consists in nding in two images the features which represent a same feature of the observed scene. It is a basic process of vision as soon as several images are used. In this paper, we propose a matching algorithm for two images, based on the use of local geometric quasi-invariants. Once a rst match is made, a projective approximation of the apparent motion and the epipolar geome...
