Remarks

This property allows you to limit identification to a subset of the forms in the FormModels collection. Set this property to true when you know that an unknown image cannot match some of your forms. For example, if you are processing 3 multi-page forms and you just recognized page 1 of form A, you may choose to exclude forms B and C from consideration until you have found all the pages of form A. The subset used is defined by the IdentificationSubset property.

Two alternates to using this property are to maintain separate IdentificationProcessor objects for the subsets or to change the FormModels collection of a single IdentificationProcessor object. Both are poor alternatives due to memory and performance issues. Each IdentificationProcessor object consumes a certain amount of RAM and having multiple copies will consume more RAM than having a single one. Using a single IdentificationProcessor object also provides that object with more opportunities to learn about your forms and improve future results. Finally, changing the FormModels collection is an especially bad idea because this object will have to repeat its analysis of the forms and that can be very expensive if you have a lot of forms.

Default value: false
