摘要: Pre-processing is a common name for operations with images at the lowest level of abstraction — both input and output are intensity images. These iconic same kind as original data captured by sensor, an image usually represented matrix function values (brightnesses). The aim pre-processing improvement that suppresses unwilling distortions or enhances some features important further processing, although geometric transformations (e.g. rotation, scaling, translation) classified among methods here since similar techniques used.
