Finitary Compositions of Two-way Finite-State Transductions
Abstract. The hierarchy of arbitrary compositions of two-way nondeterministic finite-state transductions collapses when restricted to finitary transductions, i.e., transductions ...

Object detection and segmentation on a hierarchical region-based image representation
In this paper we present a general framework for object detection and segmentation. Using a bottom-up unsupervised merging algorithm, a region-based hierarchy that represents the ...

On the jump classes of noncuppable enumeration degrees
We prove that for every Σ0 2 enumeration degree b there exists a noncuppable Σ0 2 degree a > 0e such that b ≤e a and a ≤e b . This allows us to deduce, from results on the...
