How accurate are the OCR recognition results? What factors affect the recognition accuracy?
OCR (Optical Character Recognition) technology can convert text in an image into an editable text format. The accuracy of its recognition results is an important indicator of the performance of OCR technology. Generally speaking, modern OCR technology has a very high recognition accuracy rate on standard printed documents, almost reaching more than 99%. However, when processing complex images, handwritten text or specific fonts, the accuracy rate may decrease.
1: Image quality
Clarity, lighting conditions, noise, etc. will affect the recognition ability of OCR.
2: Font and font size
Some special fonts or too small fonts may be difficult to be accurately recognized by the OCR system. Font complexity is also an important factor, and complex font structure will increase the difficulty of recognition.
3: Text layout
When the text is arranged in disorder, overlapped, tilted, or there are a lot of interfering elements, the recognition accuracy of the OCR system will be affected.
4: Multi-language and multi-alphabet system
The OCR system needs to support multiple languages and character sets. Different languages and character sets have different recognition difficulties, which will also affect the overall recognition accuracy.
