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
Package: com.dynamsoft.utility
Inheritance: CapturedResultFilter -> MultiFrameResultCrossFilter
public final class MultiFrameResultCrossFilter extends CapturedResultFilter
Methods
| Method | Description |
|---|---|
MultiFrameResultCrossFilter |
Initializes a new instance of the MultiFrameResultCrossFilter class. |
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. |
setMaxOverlappingFrames |
Sets the max referencing frames count for the to-the-latest overlapping feature. |
getMaxOverlappingFrames |
Gets the max referencing frames count for the to-the-latest overlapping feature. |
enableLatestOverlapping |
Enables the to-the-latest overlapping feature. The output captured result will become a combination of the recent results if the latest frame is proved to be similar with the previous. |
isLatestOverlappingEnabled |
Determines whether the to-the-latest overlapping feature is enabled for the specific result item type. |
setResultCrossVerificationCriteria |
Sets the cross-verification criteria for specified result item types. |
getResultCrossVerificationCriteria |
Gets the cross-verification criteria for a specified result item type. |
MultiFrameResultCrossFilter
Initializes a new instance of the MultiFrameResultCrossFilter class.
