Document Detection Section

The Document Detection Section is designed to detect the edges of a document.

{
    "Section": "ST_DOCUMENT_DETECTION",
    "ImageParameterName": "ip_ddnDefault",
    "StageArray": []
}

Section

The section is named ST_DOCUMENT_DETECTION.

ImageParameterName

Specifies the ImageParameter to apply in the stages of this section.

Parameter Summary
Type string
Range It must be one of the name that defined under `ImageParameterOptions`
Default Value ip_ddnDefault

StageArray

StageArray is a parameter that specifies the stages within the Document Detection Section. A Stage is the smallest step significant enough to involve users in image processing.

The Document Detection Section consists of stages show below:

SST_ASSEMBLE_LONG_LINES
- It is designed at the stage level to assemble relatively long line segments to facilitate the assembly of more advanced line segments.
SST_ASSEMBLE_LOGICAL_LINES
- It is designed at the stage level to assemble line segments based on certain criteria to serve the assembly of quadrilateral corners.
SST_DETECT_CORNERS
- It is designed at the stage level to detect corners of quadrilaterals that meet the specified conditions.
SST_DETECT_EDGES
- It is designed at the stage level to detect edges of quadrilaterals that meet the specified conditions.
SST_DETECT_QUADS
- It is designed at the stage level to detect complete quadrilaterals.
