This will help the user identify that the document has been tampered with. After training a font with NewOCR, the image’s font can be detected. Assume this value is manually changed to “41000” and the “4” is written in a size 12 font. Process a batch to verify the changes in the HOCR schema. Support for batches executed of Encrypted Batch Classes. Détection de l'écriture manuscrite avec reconnaissance optique des caractères (OCR) L'API Vision peut détecter et extraire du texte à partir d'images : DOCUMENT_TEXT_DETECTION extrait le texte d'une image (ou d'un fichier). After training a font with NewOCR, the image’s font can be detected. ON/OFF switches have been added to the RECOSTAR_HOCR and NUANCE_HOCR plugins which the user can configure to retrieve font information. In Ephesoft Transact v4.5.0.0, a new Font Recognition switch has been introduced to detect potential fraud and tampering with processed documents. The system will recognize the font size and style in the HOCR file. Note: The Recostar OCR engine does not recognize combinations of font styles. This does the same thing as the OCRUtils#removeLeadingSpaces(String) method used in the basic scanning example, but modifies the ImageLetter object so the first character will be a non-space. The HOCR schema has been revamped to include font information from the data fetched by the Recostar and Nuance OCR engines. Assume this value is manually changed to “41000” and the “4” is written in a size 12 font. This feature is available only in the Recostar and Nuance OCR engines. In the screenshot below you can see the difference in the HOCR schema when the Font switch is turned OFF. Conclusion. The information about font family and size is not fetched when the switch is turned OFF. Also, a tag entitled “Style” has been added in the HOCR file which contains information about the style (Bold, Italics, and Underline) of the span. OpenCV (Open source computer vision) is a library of programming functions mainly aimed at real-time computer vision.OpenCV in python helps to process an image and apply various functions like resizing image, pixel manipulations, object detection, etc. Our proposed method significantly outperforms the most closely related model designed for document manip-ulation detection. Turn OFF the NUANCE FONT SWITCH and save your changes. I'm scanning documents that might have different parts with different fonts, and it would be useful to have this information. If style information is not fetched, its value is “None”. Fraud Detection Using OCR Font Switch. For this example, the image being scanned is the following, written in 20pt (27px) font: This will be using similar code to the basic training and scanning, the only difference being the definition of OCRActions which provides the method being used to detect font sizes in the future. The HOCR file reflects the font style (Bold, Italics, and Underline) and font size if the Font switch is turned ON in the RECOSTAR_HOCR or NUANCE_HOCR plugins.

For example, the original amount of a field in a document is “1000” and the font size is 11. EasyOCR is a python package that allows the image to be converted to text. The following Web Services have been modified to include font information in the HOCR file: The following Web Service can be configured to obtain font information in the HOCR file: createOCR (a new parameter fontSwitch with an ON/OFF setting has been added to the input .xml file). Also, a tag entitled “Style” has been added in the HOCR file which contains information about the style (Bold, Italics, and Underline) of the span. The following changes have been made to implement this feature: The newly generated HOCR schema now includes the font size of each character in the span. Note: Tesseract does not provide any information on font detection. By default, the Font switch is set to OFF. Turn OFF the NUANCE FONT SWITCH and save your changes. Font Detection. For example, the style value would be “None” if a character string was both bold and underlined. Database Permissions – Can non-DB Owner permissions be assigned for successful operation? As like with normal scanning, shutting down the database can be done right after the scanning, but is usually placed at the end of a program incase the database needs to be reused.
