This ABBYY FineReader Engine (SDK) sample includes a set of image preprocessing tools and allows you to watch how this or that tool influences recognition quality. You can use general preprocessing tools (like page orientation and skew correction), filter colors, use special preprocessing tools for photos, and enhance appearance of the images.

Description

The sample processes specified image twice: once it process original image, and then corrected image. Then it compares recognized documents and shows the result of comparison together with the original and corrected image. Uncertainly recognized characters are highlighted on the images.

To view how it works:

  1. Select the image to process.
  2. Specify recognition language of the processing document.
  3. Select the tools, which should be used for image preprocessing.
  4. To run the sample, click Go.
