Enum BarcodeReader.BarcodeImageCorrection
An enum defining strategies for cleaning pixels in noisy input documents such as scans and photographs. In essence BarcodeImageCorrection helps separate dark barcode pixels from background patterns in images automatically.
Aggressive BarcodeImageCorrection is not always better. BarcodeImageCorrection will take longer to perform (use more CPU cycles). We recommend experimenting with diIferent levels of BarcodeImageCorrection starting with the lowest settings first and gradually working up from there.

Syntax
public enum BarcodeImageCorrectionFields
| Name | Description |
|---|---|
| CleanNonBlackPixels | Barcode pixels area filtered to remove all pixels than are at not least 80% black. Pixel Thresholds are 80% dark or greater and a relative color tint of less than 40% from black |
| DeepCleanPixels | Barcode pixels area filtered to remove all but the darkest pixels and pixels of very distinctly non-black color Pixel Thresholds are 70% dark or greater and a relative color tint of less than 30% from black |
| LightlyCleanPixels | Barcode pixels area lightly filtered to remove light pixels and pixels of very distinctly non-black color. Pixel Thresholds are 40% dark or greater and a relative color tint of less than 50% from black |
| MediumCleanPixels | Barcode pixels area filtered to remove light pixels and pixels of very distinctly non-black color Pixel Thresholds are 60% dark or greater and a relative color tint of less than 40% from black |
| None | Default. Barcode images are not preprocessed. Fastest. |
