Enum BarcodeImageCorrection

Specify the amount of pre-processing to clean pixels in noisy input documents. Useful for scans and photographs that may have visual noise obstruction. Internally, this process aims to separate dark barcode pixels from background patterns in images.

Please understand that pre-processing is CPU-heavy and we recommend experimenting with different settings starting with the lowest settings first and gradually working up from there.

public enum BarcodeImageCorrection

Fields

Name	Description
CleanNonBlackPixels	Alternative cleaning option. Barcode pixels area filtered to remove all pixels than are at not least 80% black.
DeepCleanPixels	Heavy Processing is performed to attempt to clarify the barcode area and make it stand out more for the reader. This is a very CPU-intensive operation and may still not improve blurry barcodes or noisy images. Please consider using our filters: https://ironsoftware.com/csharp/ocr/tutorials/c-sharp-ocr-image-filters/
LightlyCleanPixels	Light Processing is performed to attempt to clarify the barcode area and make it stand out more for the reader.
MediumCleanPixels	Medium Processing is performed to attempt to clarify the barcode area and make it stand out more for the reader. This is a CPU-intensive operation. We recommend experimenting with all levels of processing to ensure you are using the weakest one required to improve performance.
None	No Processing (Default). Barcode images are not preprocessed at all.
