Embodiment approach

[0030] Further, before the determination of the background color of the scanned card image in step S103, it may further include: performing a preprocessing action on the scanned card image including image noise removal.

[0031] Furthermore, after the completion of the segmentation in step S105 and before filing and storing in step S107, it may also include: performing post-processing on the segmented card scan sub-images, and performing direction correction operations on rotated cards.

[0032] As can be seen from the above, the card scanning image segmentation method provided by the present invention is based on different background types in the card scanning image (including a black background type that is significantly different from the background color of the card and a white background type that is similar to the background color of the card) ) and choose different segmentation logic processing (black background logic processing and white background logic processing), so...

Abstract

The invention provides a segmentation method of a card scan image, which comprises the steps of receiving the to-be-processed card scan image containing a plurality of cards, judging background types of the card scan image, selecting different segmentation logical processings according to different background types to segment a plurality of card scan subimages, allowing only one card to exist in each card scan subimage, and filing and storing the segmented card scan subimages, wherein the background types comprise a black background and a white background, and the segmentation logical processings comprise black background logical processing and white background logical processing. Compared with the prior art, the method can simplify scanning and identification processes of business cards and reduce the time and labor intensity of operators.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for segmenting a scanned image containing multiple cards. Background technique [0002] Today's business contacts and business development are customary to introduce identity in the form of distributing business cards, and the role of business cards also reflects its important value in future contact and record keeping. However, when the number of business cards accumulates a lot, using traditional business card holders to collect business cards is inconvenient to manage and search, and wastes a lot of time and energy virtually. [0003] With the development of electronic technology, the general management method of converting the information on the business card into electronic data and storing it in electronic equipment has been favored by the public, for example: manually input the business card information into the electronic device, use the camera to take t...
