This sample shows how ABBYY FlexiCapture Engine can process images with overlaid stamps and ink inscriptions.

The illustration below shows, that this can be a real issue, because the text/characters under the stamp are not detected and can not be recognized.


FineReader Engine 11 can also remove stamps, screenshot Image Preprocessing Sample

Description

The sample processes images from the specified folder using the selected Document Definition. The sample creates a FlexiCapture processor and specifies a special image source for it. This image source is implemented in such a way that it can perform preprocessing of the images. The processor removes stamps using this image source and then recognizes the images. The result of processing is displayed in a form of a tree with recognized data. The recognized fields are highlighted on the image.

To view how it works:

  1. Select the folder with images to process and the Document Definition, which should be used for processing. You can restore the default settings by clicking Restore defaults.
  2. To recognize an image, click Process image.
  3. After the image is recognized, all the stamps are removed from the image, and the recognized data appears in a tree to the right of the image. You can click on an element in the tree to view it on the image.
  4. To navigate between images, use the buttons below the image.
