Embodiment Construction

[0023] Preferred embodiments of the present disclosure will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical embodiment, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and those Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0024] Here, it should be noted that, in order to avoid obscuring the technical solution of the present disclosure due to unnecessary details, only the device structure and / or processing closel...

Abstract

The present disclosure provides a document processing device and device and a scanner. The document processing device includes: a text line extraction unit, which extracts text lines from the input document; a language classification unit, which determines whether the language of the input document needs to be processed by OCR; an OCR unit, which determines that OCR needs to be performed , determining the OCR confidence degree by performing OCR processing; a graphical feature recognition unit, which determines the graphical feature recognition confidence degree; and a determination unit, which determines the combined confidence degree based on at least one of the graphical feature recognition confidence degree and the OCR confidence degree, And the orientation of the input document is determined based on the combined confidence. According to the technical solution of the present disclosure, the orientation of the document can be better judged, and it is especially suitable for judging the orientation of the document when the image quality of the document is degraded.

Description

technical field [0001] The present disclosure relates to a document processing device, a document processing method, and a scanner, and more particularly, to a document processing device, a document processing method, and a scanner for determining an orientation of an input document. Background technique [0002] With the increasing demand for digital libraries and document digitization, a large number of documents in the form of physical carriers (such as paper documents, film documents, etc.) need to be scanned and processed by the Document Image Processing System (DIPS). Convert to an electronic document in a specified format. As an important step in the document image processing system, it is often necessary to automatically determine the direction of the document from the scanned document image (for example, from left to right, from right to left, from bottom to top, and from top to bottom. candidate direction). However, the performance of the discrimination process o...
