Be default elDoc IDP assumes that input files (images) are provided with average or good scanning quality, as such they are pre-processed with the default settings optimized for processing images of the average quality.

elDoc IDP also allows to process images provided with poor and bad quality (noisy background or color background, twisted and rotated photos of documents, etc.), but such scanned documents may require custom preprocessing settings. For this purpose elDoc IDP provides possibility to define custom parameters per RecoForm so when documents are to be processed with the given RecoForm they are at first place re-pre-processed with custom settings and only after that - IDP will be performed.

This page provides overview of the available advanced settings.

Recognition Form Advanced Settings

Advanced settings are set via the Advanced settings configuration area of the RecoForm.

Advanced settings description

Advanced setting param name	Data type	Default value	Description	Triggers custom pre-processing
idp_recoform_table_removelines	Boolean	false	Enables functionality for removing lines on the page during tables processing. To be enabled for images with the broken table border lines.
idp_recoform_table_ancundtblusebottom	Boolean	false	Use bottom left point of anchor for calculating location of table end.
idp_recoform_pattern_date	String		Date pattern to be used for parsing date fields on the conversion phase.
idp_recoform_use_source	Boolean	false	Switches RecoForm to use source image instead of the pre-processed image for the RecoForm processing.
idp_recoform_custom_id	String		Id of the custom RecoForm which is loaded as plugin.
idp_recoform_morphology	String		Enables artifacts removal and sets size of the artifact to be removed during image pre-processing. Min value: "0x0" (disabled) Max value: "99x99"
idp_adaptive_threshold	Boolean	false	Enables adaptive thresholding.
idp_resolution_threshold	String		If source image resolution is below defined threshold in at least one dimension document will be sent to validation. Min value: "10x10" Max value: "99999x99999"
idp_ocr_mode_sparse_text	Boolean	false	Sets OCR recognition mode to Sparse Text.
idp_recoform_strict_layout	Boolean	false	Enforces strict template layout for the RecoForm. When this value set to true anchors' positions are used for calculating page scale.
