Abstract
A system and method are disclosed for representing a data set by selecting a data transformation function and a data masking function. Preferably, the data set transformation and data masking functions are used to generate an attractor that more accurately represents the data set than an attractor generated by the data transformation function alone. The data masking function is a set of exclusionary data elements which are used to terminate data transformations for data elements which generate the attractor. Preferably, the data masking function is defined as a polygon for a two dimensional space. When the data masking function is incorporated with the data transformation function, the attractor normally produced by the data set transformation function is constrained to more accurately represent the data set. The data masking function may be used with any data transformation function including those comprised of complex, projective, affine maps, fractal transform, or fractal transform error function transformations. Deterministic and random iterative methods may be used to generate the constrained attractor that represents the data set to be represented.
