Image processing unit to determine spectral values of orthogonal transformations from digitised grey values of the image sensor

摘要

The invention concerns an image processing unit to determine spectral values of orthogonal transformations from digitised grey values of the image sensor. Such operators can be advantageously used for recognition and measurement of linear and surface structures. According to the invention, a signal weighting module is connected to the second input of the arithmetic unit, and the output of the latch which is assigned to the arithmetic unit is connected both to the first input of the arithmetic unit and, via a bidirectionally operating collecting register, to the result memory.
