Quality of the Original Image or pdf

The source arrives in the system in unarranged form. OCR cannot read and recognize different formats, variants, and layouts. It cannot read specific characters such as signatures, numerical as well. Due to the reasons, OCR lacks in quality and shows up errors. Before processing it into the software, it must undergo pre-processing methods. The pre-processing method increases the accuracy as well as the efficiency. It also results in avoiding errors. Production of errors results in poor efficiency and quality of work. So, pre-processing methods are necessary.

The pre-processing methods are simple. It can be easily determined. If the source of the image or pdf is good, it will be visible to the native eyes. After processing this document results in better accuracy and produces no errors. It also produces good efficiency of work. If the original documents are not visible to the eyes results in containing errors. It will not produce good quality of work. The higher the quality of the source, the easier OCR works. The higher the quality of the document or scanned images, the easy it is to separate the characters from the original document. Pre-processing methods are important for OCR. Pass the documents through pre-processing methods to obtain the best OCR accuracy and quality.

Quality of the OCR engine

There is no software or application available. Every software or application works in a different algorithm. Mainly, the difference comes in quality. Comparing the accuracy of OCR is also dependent on the OCR engine. It is also necessary to choose a proper quality OCR engine. There is software that results in faster data extraction. It recognizes texts but does not extract data as accurately as the original image. If the quality of the OCR engine is not good, it will show up many more complications.
