Why is the accuracy of OCR text recognition very low?

The reasons for the low accuracy rate of using OCR text recognition software are as follows:

1. The recognized text is not clear enough;

2. Not using professional OCR text recognition software;

3. **The text should not be scribbled.

Basically, the OCR text recognition accuracy is low due to the above three reasons.

The recognition accuracy of OCR technology is instantly able to recognize text and convert almost all types of printed documents, including articles in books and magazines with complex layouts.

If your company needs to identify a large number of text information, it is recommended to use the OCR text recognition system in the future, you can call the specific link, I hope it can help you

This is related to the clarity of the **, if the clarity is high, abbyy is recommended, but this software is too big, you can use the love dot converter (lovedot.cn), this recognition accuracy is very high, and it can output word and excel

First of all, the image mode of scanning is black and white, the resolution is set to 300dpi, and the color level is set to 128, so the recognition rate is more than 90%, and I often use Shangshu.

Normally, the recognition accuracy of OCR text recognition software will not be low, the key is still the ** or other media that are recognized, and the accuracy of OCR text recognition is high, you can try.

The reason for the font is that bold will reduce his recognition.

The best recognition rate is Songti.

The business card recognition rate of Yunmai can reach 96%, which is a very useful network information management tool. Expert.

In addition, the second-generation ID card recognition software of Yunmai can reach 98%, which is usually used in the field of intelligent and rapid entry of personal information by mobile terminals, and is widely used in systems such as finance, telecommunications, and public security.

Recently launched a cloud identity** for user experience.

OCR text recognition software which is better.

OCR Character Recognition BAI

Which software has a high recognition accuracy?

Go online to find a special type of text recognition software for "Xunzhi OCR Text DAO Recognition". OCR text recognition is the most powerful ** (**format or scanned) to word software I have ever seen.

It is an OCR software,The interface is relatively concise and clear,Support 100 language recognition,Especially the mixed multi-language recognition effect is also very good:After installation,First identify the text on the **,And then corrected the identification error again,In this way,Format conversion from JPEG file to word。

The above recommended OCR text recognition software has an accuracy rate of more than 97%.

1. Choose all the text recognition software software. Choose a good text recognition software that suits you is the basis for doing a good job in text recognition, generally do not use the OEM software that comes with the scanner, OEM OCR software has few functions and poor effects, and some even do not have Chinese recognition. The ECR text recognition software has conducted in-depth research on Chinese characters, and also has the function of associating Chinese characters, and guesses the unclear word according to the previous word or the next word of the recognized word, so the recognition effect is very good.

Users of text recognition software should also make some preparations before recognition, so as to get better recognition results.

Binarization: The camera shoots, most of them are color images, the color image contains a huge amount of information, for the content of the **, we can simply divide it into foreground and background, in order to make the computer faster, better recognition of text, we need to process the color map first, so that only the foreground information and background information, you can simply define the foreground information as black, the background information as white, this is the binary diagram.

Noise removal: For different documents, we can define noise differently, and denoising according to the characteristics of the noise is called noise removal.

4. Layout analysis:

The process of dividing the document into paragraphs and branches is called layout analysis, due to the diversity and complexity of the actual document, therefore, there is no fixed, optimal cutting model.

Character cutting: Due to the limitation of photographic conditions, it often causes character adhesion and pen breakage, which greatly limits the performance of the recognition system, which requires text recognition software to have character cutting function.

I believe that everyone will encounter the problem that the recognition rate of OCR text recognition software is very low;

The following takes "Swift OCR Text Recognition Software" as an example to share a method to improve the recognition rate of OCR text recognition software;

Second, you need to choose the recognition format and recognition effect;

Third: Use professional OCR text recognition software.

Hopefully, the above narrative can help you!
