MultiFrameResultCrossFilter

The MultiFrameResultCrossFilter class is responsible for filtering captured results. As a default implementation of CapturedResultFilter, it provides results verification and duplicate results filtering features.

Definition

Namespace: Dynamsoft.Utility

Assembly: Dynamsoft.Utility.dll

Inheritance: CapturedResultFilter -> MultiFrameResultCrossFilter

public class MultiFrameResultCrossFilter : CapturedResultFilter

Methods

Method Description
MultiFrameResultCrossFilter Default constructor of a MultiFrameResultCrossFilter object.
EnableResultCrossVerification Enable result cross verification feature to improve the accuracy of video streaming recognition results.
IsResultCrossVerificationEnabled Determines whether the result cross verification feature is enabled for the specific captured result item type.
EnableResultDeduplication Enable result deduplication feature to filter out the duplicate results in the period of duplicateForgetTime for video streaming recognition.
IsResultDeduplicationEnabled Determines whether the result deduplication feature is enabled for the specific result item type.
SetDuplicateForgetTime Sets the duplicate forget time for the specific captured result item types.
GetDuplicateForgetTime Gets the duplicate forget time for a specific captured result item type.
Dispose Releases all resources used by current object.

MultiFrameResultCrossFilter

Default constructor of a MultiFrameResultCrossFilter object.

MultiFrameResultCrossFilter()

EnableResultCrossVerification

Enable result cross verification feature to improve the accuracy of video streaming recognition results.

void EnableResultCrossVerification(int resultItemTypes, bool enabled)

Parameters

IsResultCrossVerificationEnabled

Determines whether the result cross verification feature is enabled for the specific captured result item type.

bool IsResultCrossVerificationEnabled(CapturedResultItemType type)

Parameters

[in] type The specific captured result item type.

Return Value

Returns a bool value indicating whether result verification is enabled for the specific captured result item type.

EnableResultDeduplication

Enable result deduplication feature to filter out the duplicate results in the period of duplicateForgetTime for video streaming recognition. The default value of duplicateForgetTime is 3000ms.

  • CRIT_BARCODE: When the text and format are identical, it is considered as the same barcode.
  • CRIT_TEXT_LINE: When the text is exactly the same, it is considered as the same text line.
  • CRIT_DETECTED_QUAD: When the quadrilateral is approximately the same, it is considered as the same quadrilateral.
void EnableResultDeduplication(int resultItemTypes, bool enabled)

Parameters

[in] resultItemTypes The or value of the captured result item types.
[in] enabled Set whether to enable result result deduplication.

IsResultDeduplicationEnabled

Determines whether the result deduplication feature is enabled for the specific result item type.

bool IsResultDeduplicationEnabled(CapturedResultItemType type)

Parameters

[in] type The specific captured result item type.

Return Value

Returns a bool value indicating whether result deduplication is enabled for the specific result item type.

SetDuplicateForgetTime

Sets the duplicate forget time for the specific captured result item types. The same captured result item will be returned only once during the period.

  • CRIT_BARCODE: When the text and format are identical, it is considered as the same barcode.
  • CRIT_TEXT_LINE: When the text is exactly the same, it is considered as the same text line.
  • CRIT_DETECTED_QUAD: When the quadrilateral is approximately the same, it is considered as the same quadrilateral.
void SetDuplicateForgetTime(int resultItemTypes, int time)

Parameters

[in] resultItemTypes The or value of the captured result item types.
[in] time The duplicate forget time measured in milliseconds. The value rang is [1, 180000].

GetDuplicateForgetTime

Gets the duplicate forget time for a specific captured result item type.

int GetDuplicateForgetTime(CapturedResultItemType type)

Parameters

[in] type The specific captured result item type.

Return Value

Returns the duplicate forget time for the specific captured result item type.
