Hence, it can be achieved through the use of a power-law transformation function [33].
The power-law transformation is mathematically represented as: R=c{X}^{gamma } (1).
The advantage of power-law transformation is that the transformation function can be controlled by varying the gamma γ values.
A morphological filter (Serra, 1998), with disk structuring element (of size 2), and power-law transformation with the basic form s= crγ (Gonzalez and Woods, 2002) are used to enhance the mitochondria objects.
These methods consist of log and power-law transformations [14,15]; low-pass, high-pass, homomorphic filtering [3]; histogram equalization [16]; contrast stretching [17]; normalization [18]; and sigmoid function [19].
Furthermore, since the assumption of log-normality in the Bark-PSD domain implies that the log-domain features are normally distributed, RASTA, preemphasis, and power-law transformations do not alter this condition.
A vector therefore may be regarded as an entity that, in n-dimensional space, has n components that transform according to a specific law of transformation having the above properties.
This law of transformation of the components has two important properties.
She works for an insurer.Beneath the interminable squabbles over Barack Obama's health law, a transformation is taking place.
When the coordinate system is changed, the components of the vector change according to a mathematical law of transformation deducible from the parallelogram law.
