Nonlocal and multivariate mathematical morphology

O. Lezoray, A. Elmoataz
2012 2012 19th IEEE International Conference on Image Processing  
In addition to providing an efficient way to construct a vectorial ordering, nonlocal configurations based on color patches can be easily handled and provide much better results than with classical local  ...  The proposed approach is fully unsupervised and consists in constructing a complete lattice from an image as a rank transformation together with a learned ordering of vectors.  ...  From this ordering, we can deduce the rank of a vector on the complete lattice L defined as r : R q → [0,m], and construct a rank image as f r :Ω→ [0,m] with f r (p i )=( r • h • f )(p i ) and p i ∈ Ω.  ...
