METHODS FOR QUALITATIVE EVALUATION OF A MATERIAL WITH AT LEAST ONE IDENTIFICATION CHARACTERISTIC
摘要
Method for qualitative assessment of material with at least one identification characteristic, whereby an electronic image sensor or digital camera is used to record a color image. From the image a first correlated electrical signal is generated. A second signal is generated from a reference image that forms a set value for the first signal. To check deviations of the recorded color image from the reference image the two signals are compared.
