Example Embodiment

[0069] Example 1

[0070] For example, on a general computer, the scanned Beijing medical outpatient fee bills are processed, using the method of the present invention, after obtaining image data in step 110, image preprocessing in step 120, and a red seal in step 130, which is suspected After the region, we get the region information of the supervisor stamp on the header of the bill and the outpatient fee stamp. After step 140, the red stamp region is extracted and the background text is removed to obtain a separate red region stamp. Finally, step 150 restores the stamp region text to obtain the removed stamp All the information of the bill afterwards.

Example Embodiment

[0071] Example 2

[0072] For example, on a general computer, the scanned Shanghai medical outpatient fee receipts are processed, using the method of the present invention, after obtaining image data in step 110, image preprocessing is performed in step 120, and a red seal is obtained in step 130. After the area, all the information of the supervisory chapter and the acceptance chapter area are obtained. After step 140, the red seal area is extracted to obtain the chapter information, and the information of the background text is removed. Finally, the text of the seal area is restored through step 150 to obtain all the information of the bill after the chapter is removed.

Example Embodiment

[0073] Example 3

[0074] On a general computer, using the method of the present invention to extract the central medical outpatient fee bills obtained by scanning, extract the red seal area, restore the text of the seal area, and achieve the separation effect.

Abstract

The invention relates to a method for separating a red seal of a medical bill. The method comprises the following steps of 110, obtaining image data; 120, performing image preprocessing; 130, obtaining a suspected red seal region; 140, extracting a red seal region; and 150, recovering a text of the seal region. According to the method, the red seal region is preliminarily obtained by utilizing two-time difference of bgr three-channel images of an image; then a non seal region is filtered in combination with characteristics of the seal; and finally mask processing is performed in combination with a coordinate position of a seal pattern to obtain text information after seal removal. The universality is high; non seal texts are filtered as more as possible; the purpose of separating the sealpattern of the bill from the characters of the text is achieved; and conditions are created for identifying complete information of the bill.

Description

technical field [0001] The invention belongs to the technical field of target detection and image processing, and relates to a method for separating red stamps of medical bills. Background technique [0002] Affixing a seal to a negotiable instrument is an important condition for a negotiable instrument to take effect, and it is also a matter that should be recorded in the form of expression of a negotiable instrument.
