Abstract: A computer-implemented method for modifying image data, the method including: loading unmodified image data; detecting at least two alphanumeric characters in an image represented by the loaded image data; selecting one or more of the detected alphanumeric characters, wherein the number of selected alphanumeric characters is smaller than the total number of detected alphanumeric characters; modifying the loaded image data by removing one or more character sections of the loaded image data, wherein each character section corresponds to an area of a selected alphanumeric character; storing the modified image data. Also provided is a corresponding data processing system, computer program product and computer-readable storage medium.

Abstract: A computer-implemented method for optical character recognition and corresponding data processing apparatus, computer program and computer-readable medium. The method includes the following: receiving image data of an input image having one or more characters and applying one or more data processing operations to the received image data, wherein at least one of the data processing operations is configured to return the one or more characters of the input image, wherein each data processing operation is selected from a predefined set of available data processing functions according to a processing configuration, wherein the available data processing functions are precompiled functions, and wherein the processing configuration can be changed at runtime.

Abstract: The invention relates to the optical detection of symbols (4) displayed on a display (2), wherein image data which contains a representation of the display (2) is obtained, comprising the steps: detection (29, 30) of a display area of the display (2) in the obtained image data; preparation (32) of the image data representing the detected display area; performing an optical symbol detection (34, 35) by using the prepared image data; and storing the symbols detected during the optical symbol detection (34, 35) in a memory (13).
