Refinable function
text:
In mathematics, in the area of wavelet analysis, a refinable function is a function which fulfils some kind of self-similarity. A function φ is called refinable with respect to the mask h if This condition is called refinement equation, dilation equation or two-scale equation. Using the convolution of a function with a discrete mask and the dilation operator D one can write more concisely: It means that one obtains the function, again, if you convolve the function with a discrete mask and then s
