The Emancipatory Systems Approache the existence of inverse elements in respect to convolution, and we derive a method to compute inverse elements without using Fourier transform. Furthermore, we get a simple condition for existence of inverse elements which is easy to verify. We describe the computation of small convolution kernel

Based on this brightness contrast along detected contour fragments, we reconstruct a smooth (weak membrane) intensity function under the boundary conditions imposed by the contour fragments. This reconstructed intensity function subseque

The dual irregular pyramid,pyramid, dual graphs, are defined only if they are planar. We prove that planarity is conserved during the construction of the pyramid. We also prove that, though only one graph of the pair is decimated, the dual graph being derived from the result of the decimation. both graphs at the next level have at most a non-increasing number of nodes.

Analytical results on the Quadtree storage-requirements, internal and external nodes differ. Besides, formulae for the expected number of internal and external nodes at a specific level of the tree are given. Next, the space efficiency of the most popular Quadtree implementations is examined. Finally, the possible usefulness of these analytical tools in other problems is commented.

A linear predictor as a regularization function in adaptive image restoration and reconstruction,tive version of the algorithm is developed by matching a weighting function to the previously selected regularization function. The adaptive regularization simultaneously leads to proper noise suppression and enhanced resolution of discontinuities.
