JSON Structure

Location in template:

LabelRecognizerTaskSettingOptions[i]
    └── SectionArray[j] (Section object)
        └── StageArray[k] (Stage object where Stage = "SST_RECOGNIZE_RAW_TEXT_LINES")
            └── DictionaryCorrectionThresholds

Parent object: RecognizeRawTextLinesStage

Example:

{
    "DictionaryCorrectionThresholds": [
        {
            "MinWordLength": 3,
            "MaxWordLength": 5,
            "Threshold": 1
        },
        {
            "MinWordLength": 6,
            "MaxWordLength": 10,
            "Threshold": 2
        },
        {
            "MinWordLength": 11,
            "Threshold": 3
        }
    ]
}

This snippet shows only the DictionaryCorrectionThresholds parameter.

To use it, embed this parameter within a RecognizeRawTextLinesStage object.

Remarks

It supports segmentation threshold.
It works together with the DictionaryPath parameter to perform error correction during the recognition process.

Parameter Details

Parameter DictionaryCorrectionThresholds consist of a group of dictionary correction threshold objects. Each threshold object includes a series of child parameters.

Child Parameter Summary

Child Parameter Name	Child Parameter Summary
MinWordLength (Required)	Description The minimum value of word length.
	Type int
	Range [0,0x7ffffff]
	Default Value 3
MaxWordLength (Required)	Description The maximum value of word length.
	Type int
	Range [0,0x7ffffff]
	Default Value 256
	Remarks MaxWordLength >= MinWordLength
Threshold (Required)	Description The maximum number of correctable characters per word.
	Type int
	Range [0,0x7fffffff]
	Default Value 1

Default Setting

If the parameter DictionaryCorrectionThresholds is not included in your template file, the following setting will be used.

{
    "DictionaryCorrectionThresholds" : 
    [
        {
            "MaxWordLength" : 256,
            "MinWordLength" : 3,
            "Threshold" : 1
        }
    ]
}

If any of MaxWordLength, MinWordLength or Threshold is missing in your dictionary correction threshold object, the default values of the child parameters will be used.
