TopOCR's Edge Enhancement Filter
TopOCR's Document Camera Image Capture Dialog provides an option that will improve the quality of captured black and white images.
This feature works by smoothing the edges of text characters.
To enable this filter, simply click on the Set Image options->Edge Enhancement button.
The result of Binarizing with the Edge Enhancement filter is seen with the image on the right.
|Default Binarization||Edge Enhanced Binarization|
This filter not only improves the readability of text, but can also increase OCR accuracy.
Note: The Edge Enhancement filter is very compute and memory intensive, and is best run on a high-end CPU with at least 2 GB of memory.
