Two new families of algorithms for computing openings of binary and label images are presented in this paper. The first family of algorithms is based on an horizontal scan, and a vertical scan that takes the result of the horizontal scan as input. With the results of these two scans it is possible to compute an opening with respect to a rectangle of any size. The second family of algorithms is based on the construction of an exhaustive list of rectangles included in an object. Rectangles of this list all have a maximal extension, i.e. no larger rectangle included in a region contains them. The opening then results from filling the output image with rectangles larger than the structuring element. After a description of the algorithms we provide a comparison of several algorithms in terms of computation time efficiency. The comparison shows that some of the new algorithms advantageously compete with existing algorithms. [less ▲]

Many information hiding techniques have recently been analyzed as they could help manage part of the digital rights. Among the general framework of information hiding, the focus has been put on steganography and on watermarking techniques. This paper proposes an entropy based technique for data embedding in images with a specific target, sometimes referred to as feature location: inclusion of a maximum amount of information instead of robustness against attacks. After an introduction, we analyze the error that results from a modification of the least significant bits. Then we describe our embedding technique. Finally we examine the upper bound of information that can be embedded in the least significant bits by means of our technique and we conclude. [less ▲]

La morphologie mathématique englobe différentes techniques de filtrage aussi variées qu'originales. Parmi l'imposante panoplie des filtres se distinguent ceux qui sont nés de la morphologie à seuillage, encore appelée morphologie floue, très en vogue à l'heure actuelle. Ce document s'inscrit dans ce courant. Nous y définissons le concept central d'érosion partielle, simple transcription d'une opération déjà connue, pour l'étendre ensuite aux notions de dilatation, d'ouverture et de fermeture partielles. À l'inverse des développements récents en ce domaine, c'est l'aspect géométrique qui y tient le haut du pavé; les opérations partielles se conçoivent comme des interactions entre objets et non en termes de lois de probabilité. Elles conduisent à une série de procédés de lissage des contours d'images binaires gérés par un seuil unique et une famille d'éléménts structurants adaptés à l'application. Des techniques similaires sont évoquées pour des images en niveaux de gris. Nous introduisons ensuite le nouveau concept de polymorphisme d'un point. Ce dernier indique pour chaque point le nombre d'éléments structurants qui contiennent ce point. C'est par son entremise que pourront s'appliquer des procédés d'optimisation de filtrage puisqu'il fournit une mesure analytique. [less ▲]
