Iv. Introduction to OCR technology
The so-called OCR (Optical Character Recognition) technology refers to an electronic device (such as a scanner or digital camera) to check printed characters on paper and determine its shape by detecting the dark and bright pattern, the character recognition method is used to translate a shape into a computer text. That is, the process of Scanning text materials, analyzing and processing image files, and obtaining text and layout information.
OCR is a technology that shares the same recognition rate. Therefore, it is the most important topic for OCR to improve the recognition accuracy rate by debugging or using auxiliary information. Intelligent Character Recognition) this is why. Different types of applications are derived based on the media of text materials and the methods in which the materials are obtained.
V. OCR recognition rate depends on
1. Image Quality. Generally, it is recommended that the image quality be higher than DPI.
2. color. Generally, the color recognition is poor, and the black and white images are relatively high. Therefore, we recommend that you use the black and white Tif format for OCR.
3. The most important thing is the font. If the handwriting recognition rate is low.
