GENERALIZED CONNECTED OPERATORS Albert

This paper deals with the notion of connected operators These operators are becoming popular in image processing because they have the fundamental property of simplifying the signal while preserving the contour information In a rst step we recall the basic notions involved in binary and gray level connected operators Then we show how one can extend and generalize these operators We focus on two...

Practical Extensions of Connected Operators

This paper deals with the notion of connected operators These operators are becoming popular in image processing because they have the fundamental property of simplifying the signal while preserving the contour information In this paper we discuss some practical approaches for the extension and the generalization of these operators We focus on two important issues the simpli cation criterion an...

Reportrapport Connected Morphological Operators for Binary Images Connected Morphological Operators for Binary Images

This paper presents a comprehensive discussion on connected morphological operators for binary images. Introducing a connectivity on the underlying space, every image induces a partition of the space in foreground and background components. A connected operator is an operator that coarsens this partition for every input image. A connected operator is called a grain operator if it has the follow...

Toeplitz Operators in Multiply Connected Regions

Stereo image analysis using connected operators

Connected operators are increasingly used in image processing due to their properties of simplifying the image with various criteria, without loosing contour's information. These properties are related to the connected operator approach that either preserves or completely eliminates a determined connected component, according to an established criterion of analysis. In this paper we will define...
