NoiseReduction - filter noise out of an image
If the NoiseReduction property is none zero then the toolkit will run an image through a noise reduction filter before scanning for barcodes. The filter removes marks from an image that are unlikely to be part of a barcode. A larger value for NoiseReduction will remove larger marks from the image, but may also destroy vital barcode. A typical value for NoiseReduction is 10.
Default value: 0
