Abstract: A novel system for recognition of patterns on presented item. A known recognition system expanded by a complementary recognition which is linked with the primary recognition. The results of the primary recognition which are not positively recognised are passed on to the complementary recognition and any characters not positively recognised by the complementary recognition are again passed on to a correction system. Here an operator classifies the unrecognised characters which are then used to teach the complementary recognition unit. Thus, the classified data of the correction system provide the training data for a continuous training process which is coupled with the correction system.

Abstract: METHOD OF REPRODUCING IMAGES WITH GREY VALUES The invention concerns a method of reproducing images with grey values,using picture elements (PELS) for the different grey values, which are represented by dot patterns with a different distribution and arrangement of the individual dots, characterized in that for each grey value there is a stock of quasi-equivalent grey value pels, and that for representing each grey value of an original to be reproduced, a pel corresponding to this grey value is selected from the associated stock of quasi-equivalent grey value patterns.

Abstract: For pattern recognition and validation, especially of hand-written signatures, the invention provides that original files of basic structures are established and stored in a reference image file (39). The structure to be verified is analyzed in the same way and with the same methods to find their significant basic structures. Information stored in the reference image file and information found as significant basic structures are compared. This comparison is performed in the order of significance sequentially or parallel at least for some information entities. Validation is performed for each single comparison step and the results are weighted. If no clear result is gained, a stepwise refinement of the recognition structures is performed by repeating the recognition and validation procedure on a higher level of information, or with other words with finer details to be analyzed.

Abstract: A method and different arrangements for the elimination of color from a multi-color image document is provided. All color information for every picture element of the image of the document is provided concurrently, for every picture element PEL the image signal of all provided colors are analyzed and for every picture element that image signal of that color is selected which has the minimum contrast relative to the background of the image document.

Abstract: OPTO-ELECTRONIC SCANNING APPARATUS The invention relates to an opto-electronic scanning apparatus with a document support on a common frame, and a scanning head scanning a document in two different directions, which is characterized in that on the frame a first carrier (4; 27) is mounted that can be driven by a first driving means (5; 18) in the first direction, that on the first carrier (4; 27) a second carrier (12) is mounted which carries a scanning head (16, 17) operating in the second scanning direction only, that the scanning head (16, 17) on the second carrier (12) is linearly movable in the second scanning direction only, and that for each direction of movement a separate driving means is provided.
