Issue:

When you scan a barcode from a screen on a monitor, a TV or a mobile phone, the image contains roughly parallel dark and light bands superimposed, called the moiré pattern. The interfering pattern makes decoding the barcode very challenging.

Solution:

Dynamsoft Barcode Reader SDK provides an image processing step to remove the moiré texture and would quickly decode the barcode. It can be configured through TextureDetectionModes.
