In the fractal coding schemes proposed so far based on Iterated Function Systems, an image is represented by a self-affine set of square blocks. In this paper, we propose a scheme of fractal image coding with blocks of variable shapes. In this scheme, the range blocks are determined by so-called splitting-and-merging method. Also, we define two kinds of range blocks, shade blocks and non-shade ...

Learning smooth sequences of multi dimensional values trajectories can be performed by a neural network approximating a function which maps the one dimensional input space time onto anm dimensional output space workspace of the trajectory The underlying structure of the proposed network and the basic learning scheme for trajectory storage has already been published in Go erke et al This paper d...

Droplet manipulation is comprised of techniques such as droplet generation, merging, and splitting, of which droplet merging is one of the major bottlenecks in achieving high-throughput analysis. Here we present a three dimensional electrode that improves the electric field uniformity and field strength experienced by two adjacent droplets undergoing merging. We conducted a systematic compariso...

We present a novel numerical method and algorithm for the solution of the 3D axially symmetric timedependent Schrödinger equation in cylindrical coordinates, involving singular Coulomb potential terms besides a smooth time-dependent potential. We use fourth order finite difference real space discretization, with special formulae for the arising Neumann and Robin boundary conditions along the sy...

In this paper, an image segmentation method based on directed image region partitioning is proposed. The method consists of two separate stages: a splitting phase followed by a merging phase. The splitting phase starts with an initial coarse triangulation and employs the incremental Delaunay triangulation as a directed image region splitting technique. The trian-gulation process is accomplished...

In this paper, a novel method for MRI volume segmentation based on region adaptive splitting and merging is proposed. The method, called Adaptive Geometric Split Merge (AGSM) segmentation, aims at finding complex geometrical shapes that consist of homogeneous geometrical 3D regions. In each volume splitting step, several splitting strategies are examined and the most appropriate is activated. A...
