How can you improve the accuracy of OCR?

5 Ways to Improve OCR Accuracy

1. Good Quality of Source Images. Before using OCR, make sure you can read the images with your own eyes.
2. Right Size of Images.
3. Remove Noise / Denoise.
4. Increase Image Contrast.
5. De-skew Original Source.

What is the accuracy of OCR?

Obviously, the accuracy of the conversion is important, and most OCR software provides 98 to 99 percent accuracy, measured at the page level. This means that in a page of 1,000 characters, 980 to 990 characters will be accurate. In most cases, this level of accuracy is acceptable.

How does OCR increase accuracy in image processing?

When it comes to improving OCR accuracy, you basically have two moving parts in the equation.

1. The Quality Of Your Source Image.
2. The OCR Engine.
3. Good Quality Original Source.
4. Scaling To The Right Size.
5. Increase Contrast.
6. Binarize Image.
7. Remove Noise and Scanning Artefacts.
8. Deskew.

What affects OCR?

Short term interest rates are influenced by the OCR. This is because banks are unlikely to lend money to people for rates less than they could receive from the Reserve Bank. Market interest rates – particularly for longer terms – are also affected by the interest rates prevailing offshore.

What does an increase in the OCR mean?

An increase in demand puts upward pressure on prices. Therefore, if the Reserve Bank increases the OCR, which then reduces demand (as discussed above), this will put downward pressure on prices, thus reducing inflation. A decrease in the OCR will have the opposite effect, resulting in an increase in inflation.

What does raising OCR mean?

Official Cash Rate
The Official Cash Rate (OCR) is the interest rate set by the Reserve Bank to meet the dual mandate specified in the Remit to the Monetary Policy Committee. Unscheduled adjustments to the OCR may occur at other times in response to unexpected or sudden developments.
