Hybrid object labelling in digital images
The application of a technique for labelling connected components based on the classical recursive technique is studied. The recursive approach permits labelling, counting, and cha...

On the Monotonic Computability of Semi-computable Real Numbers
Let h : N → Q be a computable function. A real number x is h-monotonically computable (h-mc, for short) if there is a computable sequence (xs) of rational numbers which converges...

QAS: Real-Time Quadratic Approximation of Subdivision Surfaces
We introduce QAS, an efficient quadratic approximation of subdivision surfaces which offers a very close appearance compared to the true subdivision surface but avoids recursion,...

Enumerating randoms
We investigate enumerability properties for classes of random reals which permit recursive approximations from below, or left-r.e. reals. In addition to pinpointing the complexity...

Periodic Sorting Using Minimum Delay, Recursively Constructed Merging Networks
Let α and β be a partition of {1, . . . , n} into two blocks. A merging network is a network of comparators which allows as input arbitrary real numbers and has the property tha...
