Symptoms

The document is being matched correctly in FlexiLayout Studio, but when it's processed in FlexiCapture, it is recognized as an Unknown Document.

Cause

The usual causes are the image quality of the used samples, unreliable elements used as Header, Footer, or other Required Elements, and different Image Processing settings in FlexiLayout Studio and FlexiCapture.

Resolution

In case you encounter a situation when in FlexiCapture the document is not being matched to the Document Definition based on FlexiLayout, it is necessary to remember the measures that can make the results better:

• Use high-quality images whenever possible.
• In FlexiLayout, use reliable objects of good quality: keywords, separators, etc.
• Make sure that the Image Processing settings are as same as possible between the two.
  FlexiCapture:
  
  FlexiLayout Studio: 
   
• Always check the hypothesis tree in FlexiLayout Studio and make sure there are no branching, empty, or unreliable (yellow) elements.
• In case there is a multi-page document in FlexiLayout Studio, make sure the Header and Footer are set correctly and the reference document is assembled correctly (indicated with a green and blue line):
   
• Make sure to always keep the number of Required elements in FlexiLayout as low as possible, because their excessive amount may cause problems such as the inability to match.
