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

Success: diskgroup FRA was mounted

The database instance name was originally Dave. Because it was made into RAC standby, db_unique_name of the database was changed to dave_st. There is no p

The company has a need, so we have to study ha. Recently the company needs to read the verification code. So we studied the image recognition.

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."

It has been nearly three months since the previous blog titled automatic identification of simple verification Codes Using gocr. Recently, verification codes have been cracked again, but this time, the verification code is more complicated. gocr is not powerful enough. The accuracy of pure digital recognition is indeed high, but the mixed numbers and letters cannot be handled. So this time, we changed Tesseract-

There are roughly two solutions for OCR in Android applications, and the most are tesseract. My little brother is here to write down the last two days of my thinking, such as defective, welcome to shoot Bricks:There are two solutions, one is to use the tesseract Cloud-service, the clock is to send the picture information to the cloud, and then get the image analysis data, the second is to use the network, the localization analysis of the picture infor
With the development of mobile phone and tablet computer and mobile communication, the information system on PC is gradually transferred to the intelligent terminal equipment. It is anticipated that over 60% of the business in the next few years will be gradually transferred to the intelligent Terminal System. OCR recognition technology is no exception, the mobile OCR recognition is also gradually emerging.
input is very slow, and very prone to error.In order to solve the pain point that the user entered on the mobile phone, the VIN code automatic recognition software was developed, and the VIN information was collected by OCR intelligent recognition technology. The actual application proves that the automatic recognition software using VIN code greatly improves the efficiency of VIN code entry, and can collect the information of VIN code in an instant.
In the day-to-day work, we often scan some information, but scanned through the scanner files we can not edit it, we can only manually input it into the computer, and then edit. This method is not only time-consuming and laborious, but also error prone, so many users are thinking, can we use some tools to directly convert scanned images into a Word document that can be edited? In fact, this kind of OCR recognition technology already exists, many of th
