If f:D->Y is a map (a.k.a. function, transformation, etc.) over a domain D, then the

**image**of f, also called the range of D under f, is defined as the set of all values that ...An

**image**of an object obtained by reflecting it in a mirror so that the signs of one of its coordinates are reversed.Let f:A->B be a map between sets A and B. Let Y subset= B. Then the preimage of Y under f is denoted by f^(-1)(Y), and is the set of all elements of A that map to elements in ...

A nonlinear deconvolution technique used in deconvolving images from the

**Hubble**Space**Telescope**before corrective optics were installed.There are several functions called "Lommel functions." One type of Lommel function appear in the solution to the Lommel differential equation and are given by ...

A deconvolution algorithm (sometimes abbreviated MEM) which functions by minimizing a smoothness function ("entropy") in an

**image**. Maximum entropy is also called the ...A finite set of contraction maps w_i for i=1, 2, ..., N, each with a contractivity factor s<1, which map a compact metric space onto itself. It is the basis for fractal

**image**...An object is amphichiral (also called reflexible) if it is superposable with its mirror

**image**(i.e., its**image**in a plane mirror).The span of an unoriented link diagram (also called the link spread) is the difference between the highest and lowest degrees of its bracket polynomial. The span is a ...

The dimension of a partially ordered set P=(X,<=) is the size of the smallest realizer of P. Equivalently, it is the smallest integer d such that P is isomorphic to a ...
