How can you improve accuracy when scraping with OCR a region that contains only digits?

Using Google OCR with the "Numbers Only" setting is an effective way to improve accuracy when scraping a region that contains only digits. This specific setting optimizes the recognition process by filtering out any unnecessary characters or elements that do not conform to numeric data. Consequently, it enhances the OCR's focus on accurately interpreting the digits presented, reducing errors that might arise if the OCR were set to recognize all characters, including letters or symbols.

When the OCR is configured to specifically target numbers, it employs algorithms designed to better detect the shapes and patterns associated with numerical characters. This tailored approach can significantly increase the likelihood of achieving accurate results in applications such as data extraction or document processing where precision is critical, especially when the data consists exclusively of digits.

Improving OCR accuracy through other approaches, such as altering font styles, adjusting image resolution, or changing the region size, may yield some benefits, but they do not specifically cater to the unique characteristics of numerical data in the way that selecting "Numbers Only" does. Reducing the OCR region size, for example, might help focus on a specific part of the image, but it might cut off crucial context needed for accurate interpretation. Similarly, using a wider font may not always guarantee better recognition of digits, particularly if
