Abstract: A method for generating real-time control parameters by a video camera for smoke-generating combustion reactions is disclosed. In accordance with the method, a video camera is used for obtaining a video signal, which is digitized and filtered temporally and spatially. The digitized video signal is divided on the basis of its signal level distribution into signal subareas to reduce the quantity of processed information. The picture elements belonging to the same subarea are combined into contiguous image areas representing a certain signal level, the subareas are combined into an integrated image, subsequent images are averaged to eliminate random disturbance, and the averaged image is displayed on a display device. This method facilitates the real-time monitoring of a combustion process.

Abstract: Randomly distributed objects of piece goods in a state of translatory movement are identified and classified on the basis of a physical property thereof. The travel path of the piece goods is observed with a detector scanning the path transversally and indicating the wanted physical property, said detector generating an electric signal proportional to the observed physical quantity at each spot of the scanning line, within the resolution capacity of the detector. Thereupon, the electric signals are treated continuously in real time and converted into binary key number groups belonging individually to each particular object in the scanning line. The key number groups are processed during the scanning recursively in classifying units nominated for each particular object during its passage past the detector, and the classification is carried out on the basis of these key number groups.
