A new algorithm for number of holes attribute filtering of grey-level images
(2015-02-01)
Article
Open AccessIn this paper we present a new algorithm for filtering a grey-level image using as attribute the number of holes of its connected components. Our approach is based on the max-tree data structure, that makes it possible to ... -
Antiextensive connected operators for image and sequence processing
(1998-04)
Article
Open AccessThis paper deals with a class of morphological operators called connected operators. These operators filter the signal by merging its flat zones. As a result, they do not create any new contours and are very attractive for ... -
Antipodally invariant metrics for fast regression-based super-resolution
(2016-03-31)
Article
Open AccessDictionary-based super-resolution (SR) algorithms usually select dictionary atoms based on the distance or similarity metrics. Although the optimal selection of the nearest neighbors is of central importance for such ... -
