CharacterNormalizationModes
Parameter CharacterNormalizationMode defines an array of character normalization mode to implement. The array index represents the priority of the item. The smaller index is, the higher priority is.
Example
{
"CharacterNormalizationModes":
[
{
"Mode": "CNM_MORPH",
"MorphOperation": "Close",
"MorphArgument": "3",
},
{
"Mode": "CNM_SKIP"
}
]
}
Parameter Summary
Parameter CharacterNormalizationModes consist of a group of character normalization mode objects. Each character normalization mode object includes a candidate mode and a series of mode arguments. The mode arguments of the character normalization mode object is shown as follow:
Mode Arguments
| Mode Argument Name | Mode Argument Summary |
|---|---|
| Mode (Required) |
Description Specifies a mode for character normalization. |
| Type String |
|
| Candidate Mode List
CNM_MORPH CNM_AUTO CNM_SKIP |
|
| Default Value ["CNM_SKIP"] |
|
| MorphOperation (Optional) |
Description Sets the morph operation. |
| Type String |
|
| Range "Erode", "Dilate", "Open" or "Close" |
|
| Default Value "Close" |
|
| Remarks "Erode": Perform erosion process. "Dilate": Perform dilation process. "Open": Perform erosion first, then perform dilation. "Close": Perform dilation first, then perform erosion. |
|
| MorphArgument (Optional) |
Description Sets the Argument ContentDirection. |
| Type int |
|
| Range [0,2] |
|
| Default Value 0 |
|
| Remarks Only available for "DM_PERSPECTIVE_CORRECTION". 0: Direction unknown. 1: Vertical direction. 2: Horizontal direction. |
