Abstract: Image processing apparatus is disclosed for splitting, for subsequent storage or processing by OCR apparatus, character images in digital form comprising connected characters, the image processing apparatus extracts an image skeleton from an input image and represents the topology of the image skeleton in a first data structure; generates, from the first data structure, second data structures representing the topologies of the results of possible splits of the input image skeleton; evaluates the second data structures and selects one of the possible splits to thereby split the input image.

Abstract: A data entry system generates an electronically stored coded representation of a character sequence from one or more electronically stored document images, comprising optical character recognition logic (90) for generating, from the document image or images, character data specifying one of a plurality of possible character values for corresponding segments of the document images; characterised by interactive display apparatus comprising: means (110) for generating and sequentially displaying, one or more types of composite image, each composite image comprising segments of the document image or images arranged according to the character data, and a correction mechanism responsive to a user input operation to enable the operator to correct the character data associated with displayed segments.
