ABBYY FlexiCapture 12 has a smart and powerful mechanism that makes it easy to set up special image enhancement profiles. We review the possibilities that ABBYY FlexiCapture 12 provides for image enhancement (including images obtained from a mobile camera) as the example of issues described in the previous article.
The first thing I want to tell you about is that ABBYY FlexiCapture 12 has a convenient preview interface that allows you to see your settings on the selected sample in real time.
So, there are the following settings for image enhancement.
Correction of geometric and perspective distortions
This setting should be applied first because the work of other ABBYY FlexiCapture 12 image enhancement tools depends on it.
ABBYY FlexiCapture 12 has a tool that automatically detects the borders of the document and crops the excess.
This is an important enhancement to improve the subsequent OCR processing, as well as improving the overall appearance of the image.
It is important that all documents have the same resolution in order for the OCR engine to cope with the recognition of the highest quality possible. Using the image enhancement settings built into ABBYY FlexiCapture 12, you can adjust the resolution to 300dpi for all images.
The main process of improving the image is completed. The following is a list of other tools built into ABBYY FlexiCapture 12, which allows to get maximum OCR quality even from images received from a mobile camera:
- correction of brightness and contrast;
- deskewing and etc.
The following shows the recognition results obtained before applying the image enhancement settings and after. The difference is really amazing.
Summarizing, we can say that ABBYY FlexiCapture 12 Image Enhancement features are a smart tool that allows you to achieve maximum OCR quality even in poor quality images obtained from a mobile camera.
