A fragmented geometric shape that can be split into parts, each of which approximates a reduced-size copy of the whole, a property which is called self-similarity. Fractals provide the mathematics behind structures in the natural universe—e.g., frost crystals, coastlines, etc.—which cannot be described by the language of euclidean geometry. Fractal analysis is providing new ways to interpret biomedical phenomena. It has been used for classifying histopathology, enzymology, and signal and image compression

Ferrari (2007) establishes a formal definition of self-similarity, as follows:
Please note we are speaking of self-similarity over time, not space.
Because this figure demonstrates self-similarity when you zoom in on the sides, students can begin discussing concepts of similarity.
1999; Niklas and Enquist, 2001), following the elastic self-similarity model (Niklas, 1994).
The example for Wavelet transformation window length T = 1000 for self-similarity parameter H values of 0.
Many images exhibit approximate self-similarity and this structure has proven very useful in applications in image compression, representation and analysis (Hutchinson, 1981; Barnsley and Demko, 1985; Barnsley et al.
Thus even the classical non-equilibrium flows can show self-similarity if properly scaled.
Fractals have two basic characteristics suitable for modeling the topography and other spatial surfaces in the Earth's surface: self-similarity and randomness.
m]) can be used as a scaling function to study the self-similarity of the phase morphology at different solidification temperatures.
The plots of the residual analysis shown in Figure 4 don't reveal systematic curves; this fact shows a good fit in the linear pattern of the bi-logarithmic representations and therefore, the characteristic of statistical self-similarity is evidenced in these coastlines.
Zooming in to the intricate boundary reveals more and more detail and self-similarity with subtle variations.
