IntroductionFast New Year, Bo Master of the application of the screen to take the words of reading glasses coding work is also in intensive progress. Here's a look at the core functional OCR in this application, which is the function of image recognition. Let's take a look at my implementation results. It's an English-language page that's been cut off on the internet, and it's my app's
In the past few monthsR D department of the companyAs an intern in pattern recognition, I have learned a lot about OCR and technology. Thank you for your guidance from teacher Lu, sun, and other teachers. I like it very much. You have gained a lot from me.
OCR (Optical Character Recognition) optical character recognition is a processing technique used to obtain character information in an image, it is a
Speaking of OCR, it means dealing with a variety of pictures.
Therefore, the quality of images is critical.
When talking about the quality of images, we have to mention the collection of images. At present, the most reliable source of image acquisition is the scanner.
The scanner is the most reliable, and the scanner that is most suitable for OCR is the key. Today we recommend several very reliable scanners
Today is. after a busy day, I finally have time to write something. Some time ago I wrote about how to recover from the existence of a backup in RAc ocr. Today I wrote about how to reconstruct ocr and olr without a backup?
The biggest tragedy is that the database is broken and the backup is gone. It reminds me of a popular saying in the past few years: "the biggest tragedy is that people are living and mone

Many netizens like to use some OCR software identification software to scan paper materials to the electronic documents, however, the use of OCR software to identify the use of time, sometimes there will be some text recognition errors, for example, "primer" to identify the word "bow 1" or "Bow I", "Bow L." So, when you encounter OCR software identification softw
For the software functions, think of four for the moment:
