Filtering Algorithms for the NValue Constraint [PDF]
Constraints, 2005 The NValue constraint counts the number of different values assigned to a vector of variables. Propagating generalized arc consistency on this constraint is NP-hard. We show that computing even the lower bound on the number of values is NP-hard. We therefore study different approximation heuristics for this problem.

Fast algorithm for Morphological Filters [PDF]
Journal of Physics: Conference Series, 2011 In surface metrology, M-system (Mean-line filtering system) and E-system (Envelope filtering system) are two filtering approaches. Although M-system has been the dominant choice and played an important role in manufacturing control, Morphological filters, that evolved from the E-system, are believed to give better results in function prediction of ...

Dilated Filters for Edge-Detection Algorithms [PDF]
Applied Sciences, 2021 Edges are a basic and fundamental feature in image processing that is used directly or indirectly in huge number of applications. Inspired by the expansion of image resolution and processing power, dilated-convolution techniques appeared. Dilated convolutions have impressive results in machine learning, so naturally we discuss the idea of dilating the ...
