Utilizing the Best Font and Size for OCR
A major challenge when it comes to OCR is getting accurate text read out of an image. The various factors that go into the chances of the OCR output being as accurate as it need be is the font. OCR softwares primarily first identify the background in the image vs. the text content on the background and then extract the text from the background. A key to this process is recognizing the font. Optimizing the font effects can be done by changing the font style and font size.
Utilizing the Best Font Style for OCR
There are many options when it comes to using the best font for OCR. One of the options is using specialized fonts that OCR picks up very well. These are the OCR A and the OCR B fonts that are more or less customized for the best OCR output. These can be easily downloaded off the Internet from an abundant number of websites. OCR A is the typical font found in ISBN labels that are stuck on products. It is useless using and tweaking regular used fonts like Ariel, Times New Roman and Helvetica among others if you want to get good quality OCR output. In a case when the output is not all that important, any of these fonts or any regular fonts used in regular printing can be used to give an output of quality that will suffice.
Using the Best Font Size for OCR
When it comes to font size that is optimum for OCR purposes, there are many other factors that one must take into consideration like the contrast of the image and the amount of content (referred to as density) among other things. The font size that has showed the best response in OCR output is anywhere between 10 and 12. Depending on the case, one can try out different things but there are some extremities that do not work at all. For example, any font size beyond 72 will make the OCR read it as image and won't extract it as text.
