Definition
Diese Klassifikationsstelle umfasst:(Für diese Definition ist die deutsche Übersetzung noch nicht abgeschlossen)
Image preprocessing specially adapted for character recognition, in particular:
- Quantising the image signal;
- Noise filtering;
- Normalisation of pattern dimensions;
- Smoothing or thinning of the pattern; skeletonisation.
Examples
FIG. 1A shows a fragment of an example image with blur in its original state.
FIG. 1B shows the fragment shown in FIG. 1A in a restored state after applying a method for restoring blurred images.
FIG. 1C shows the fragment shown in FIG. 1B after being binarised.
FIG. 1D shows the fragment shown in FIG. 1A after being binarised without applying a method as described herein.
