What does OCR (Optical Character Recognition) mean
This technology system is used to identify handwritten or printed content through digital images, eg a redacted paper record.
The basic OCR course involves examining the content of a record and interpreting the characters into a code that can be used to process the information.
OCR is also sometimes referred to as text recognition. OCR frameworks consist of a combination of hardware and software that are used to alter actual reports in machine-readable content. For example, a scanner or circuit board, it is used to repeat or read the text, while the software prepares the text in a high-level style. The software can also harness technical know-how to implement more advanced smart character recognition strategies such as accent identification
In the present era, the goal we seek is to understand each topic in the ORI system in question. For the purposes of ease of reading, we have divided the item into several sections:

How does the OCR system work?
1- Pre-processing: Here, image enhancement techniques are applied (increasing the contrast between colors and de-blurring), then converting the image from a color image to a black and white image (binarization), and the useless contents of the image are also removed. Like long lines. The image is also analyzed.
For example: If a tilted table is detected in the image, the system rotates the image, so that the tables' lines become horizontal and vertical only. It also reduces the width of the lines (thinning). Consequently, this stage results in the identification of areas of interest.
In light of the analysis of the page, it is divided into several parts, and each part is treated separately.
2- Character recognition: This process often takes place in two stages, so that the initial survey paves the way for the final second scan.
