摘要：Methods for determining the transfer function of a signal-processing systemthat do not require a known input signal. The methods are based on two representations
1(x) and I(x) of an object, which the system has produced from differently scaled inputsignals originating from the object, or from a representation I(x) of a first object and froma representation I(x) of an object that is geometrically similar thereto but has beenscaled differently. The representations are either given or are produced at the start ofthe method. According to the invention, the representations are transformed into aworking space, and sections that relate to the same region of the object are selected ineach case. The quotient of the functions corresponding to these two sections in theworking space from which the unknown input signal comes makes it possible to clearlydetermine the transfer function sought. Various methods are indicated for this
determination. The method can be used, in particular, to improve images from electronmicroscopes for which there are no suitable test structures for determining the transferfunction.
