TL;DR: A document processing device for performing separate operations on at least two different kinds of documents, such as bills and associated vouchers, or orders for payment such as checks, provided with transport means for moving documents of a first kind, the bills, in a continuous movement along at least a reading station, and with transport mean for moving the checks, stepwise along an encoding station as mentioned in this paper.

TL;DR: In this article, an error-indicating character reader is used for reading characters on the documents, an operator's console for manually inputting characters rejected by the character reader, and a sorter for sorting the documents into groups.
Abstract: A high-speed apparatus that processes a stack of documents such as bank checks. The apparatus includes a feeder for serially feeding the documents, an error-indicating character reader for reading characters on the documents, an operator's console for manually inputting characters rejected by the character reader, and a sorter for sorting the documents into groups. The error-indicating character reader includes a character reader, a printer located a fixed distance from the character reader and an AC synchronous motor that drives each document serially past the reader and printer in a continuous motion. The character reader provides a first electrical signal when it cannot read a character. A motor velocity detecting means provides a second electrical signal representative of the motor velocity. A variable delay means that includes a phase locked loop and shift register circuitry delays the first electrical signal (can't read from the character reader) a variable time which time depends upon the second electrical signal (motor velocity). The output of the variable delay means commands the printer to print a mark beside the unreadable (rejected) character.

TL;DR: Some of the basic techniques of picture analysis are introduced: correlation, or matching of pictures; transformations and their uses, including their application to normalization for recognition purposes; parametrization, or property measurement, for picture classification; and segmentation of a picture into parts for purposes of description, with emphasis on segmentation based on region connectivity.
Abstract: Picture recognition and analysis has numerous applications in all fields of technology, from medical diagnosis to document processing. This paper introduces some of the basic techniques of picture analysis: correlation, or matching of pictures; transformations and their uses, including their application to normalization for recognition purposes; parametrization, or property measurement, for picture classification; and segmentation of a picture into parts for purposes of description, with emphasis on segmentation based on region connectivity. Examples are given showing how each of these techniques is important in practical applications.

TL;DR: In this article, the authors propose to increase the document processing speed by dividing the document running speed into the speed in the reader and other speed, and feeding the document with high speed other than the part in which intermittent feed is not made.
Abstract: PURPOSE:To increase the document processing speed, by dividing the document running speed into the speed in the reader and other speed, and feeding the document with high speed other than the part in which intermittent feed is not made.
