چکیده

A non-linear digital filter is presented in this paper: this filter aims at extending the concept of scalar rank-ordering in the case of multichannel images. The filter is based on two steps: 1) a transformation from a p-dimensional steps to a onedimensional space by means of a space filling curve; 2) a scalar median filtering step. Results which demonstrate the advantages and the good restoration computational performances of the filter are shown.

A new approach to vector median filtering based on space filling curves

The availability of a wide set of multidimensional information sources in different application fields (e.g., color cameras, multispectral remote sensing imagery devices, etc.) is the basis for the interest of image processing research on extensions of scalar nonlinear filtering approaches to multidimensional data filtering. A new approach to multidimensional median filtering is presented. The ...

A classical morphological approach to color image filtering based on space filling curves

In the last decade, nonlinear image processing algorithms have been developed for noise removing. With respect to linear methods, they present the advantage of minimizing distortions of informative characteristics. Morphological filters are a class of nonlinear techniques that have been successfully applied in filtering monochromatic images, but their extension to vectorial -valued images encou...

Approximation and Analytical Studies of Inter-clustering Performances of Space-Filling Curves

A discrete space-filling curve provides a linear traversal/indexing of a multi-dimensional grid space. This paper presents an application of random walk to the study of inter-clustering of space-filling curves and an analytical study on the inter-clustering performances of 2-dimensional Hilbert and z-order curve families. Two underlying measures are employed: the mean inter-cluster distance ove...
