Branched iterated function system (IFS) models with positioners for biological visualizations
Bio-Algorithms and Med-Systems, 2015Abstract Background: While researching new algorithms for computer graphics, we focused on the ones that are useful in modeling biological formations. Iterated function systems (IFS) are commonly used to visualize fractals or 3D self-similar objects. Their main advantage is the brevity.

Deterministic algorithms for decoding IFS (iterated function system) sets involve determining all the IFS (dynamic) descendants of seed pixels. Realistic algorithms require pruning of previously encountered pixels on the descendant tree. Timing data are reported for the random iteration algorithm, and for three new deterministic algorithms: the ...

A Dupin cyclide can be defined, in two different ways, as the envelope of an one-parameter family of oriented spheres. Each family of spheres can be seen as a conic in the space of spheres. In this paper, we propose an algorithm to compute a characteristic circle of a Dupin cyclide from a point and the tangent at this point in the space of spheres ...

Fractal arrays based on iterated functions system (IFS)
IEEE Antennas and Propagation Society International Symposium. 1999 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.99CH37010), 2003Fractal arrays have been suggested, mostly in order to obtain some kind of self-similar features in the radiation patterns. This, in turn, will allow a multi-band frequency usage of the array. Most of the previous work done in this area deals with fractal arrays in which the distance between the elements is some fractal function (like the Cantor set ...

A phoneme recognition method is presented based on fractal theory. Fractal dimension and IFS (iterated function system) parameters that represent the methods to calculate the fractal dimension are investigated for word segmentation. The IFS matrices and the eigenvalues of the covariance matrix are proposed for phoneme recognition.

Plant Simulating Based on Bilinear Transformation Iterated Function System [PDF]
Procedia Engineering, 2012 For solving the problem that typical Iterated Function System(IFS for short) attractor is very “regular”,we attempt to use bilinear transformation IFS through geometric approach, and use it to simulate fractal plant.

On the topology of the limit sets of non-autonomous iterated function systems
Since Mandelbrot's seminal work, there has been growing interest in the geometric nature of fractals. While the topological properties of the limit sets of IFSs have been studied -- notably in the pioneering work of Hata -- many aspects remain poorly understood, specially in the non-autonomous setting.Nakajima, Yuto, Watanabe, Takayuki
