Example

{
    "QuadrilateralDetectionModes": [
        {
            "Mode": "QDM_GENERAL",
            "MinQuadrilateralAreaRatio" : 30
        }
    ]
}

Parameter Summary

QuadrilateralDetectionModes consist one or more mode objects. Each mode object contains a candidate mode and other mode arguments.

Mode Arguments

Mode Argument Name	Mode Argument Summary
Mode (Required)	Description Specifies a mode for quadrilateral detection.
	Type String
	Candidate Mode List QDM_GENERAL QDM_SKIP

MinQuadrilateralAreaRatio (Optional)	Description The minimum ratio between the target document area and the total image area. Only those exceeding this value will be outputted (measured in percentages).
	Type Int
	Value Range [0,100]
	Default Value 0, indicates the use of automatic exclusion logic to filter out small quads. When this value is changed to anything other than 0, the automatic filtering logic will be disabled.
