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
Module: dynamsoft_utility
Inheritance: CapturedResultFilter -> MultiFrameResultCrossFilter
class MultiFrameResultCrossFilter(dynamsoft_capture_vision_router.CapturedResultFilter)
Methods
| Method | Description |
|---|---|
__init__ |
Initializes a new instance of the MultiFrameResultCrossFilter class. |
enable_result_cross_verification |
Enable result cross verification feature to improve the accuracy of video streaming recognition results. |
is_result_cross_verification_enabled |
Determines whether the result cross verification feature is enabled for the specific captured result item type. |
enable_result_deduplication |
Enable result deduplication feature to filter out the duplicate results in the period of duplicateForgetTime for video streaming recognition. |
is_result_deduplication_enabled |
Determines whether the result deduplication feature is enabled for the specific result item type. |
set_duplicate_forget_time |
Sets the duplicate forget time for the specific captured result item types. |
get_duplicate_forget_time |
Gets the duplicate forget time for a specific captured result item type. |
set_max_overlapping_frames |
Sets the max referencing frames count for the to-the-latest overlapping feature. |
get_max_overlapping_frames |
Gets the max referencing frames count for the to-the-latest overlapping feature. |
enable_latest_overlapping |
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. |
is_latest_overlapping_enabled |
Determines whether the to-the-latest overlapping feature is enabled for the specific result item type. |
__init__
Initializes a new instance of the MultiFrameResultCrossFilter class.
def __init__(self):
enable_result_cross_verification
Enable result cross verification feature to improve the accuracy of video streaming recognition results.
def enable_result_cross_verification(self, result_item_types: int, enabled: bool) -> None:
Parameters
result_item_types A bitwise OR combination of one or more values from the EnumCapturedResultItemType enumeration.
enabled Set whether to enable result verification.
See Also
is_result_cross_verification_enabled
Determines whether the result cross verification feature is enabled for the specific captured result item type.
def is_result_cross_verification_enabled(self, type: int) -> bool:
Parameters
type The specific captured result item type. It is a value from the EnumCapturedResultItemType enumeration.
Return Value
Returns a bool value indicating whether result verification is enabled for the specific captured result item type.
See Also
enable_result_deduplication
Enable result deduplication feature to filter out the duplicate results in the period of duplicateForgetTime for video streaming recognition.
def enable_result_deduplication(self, result_item_types: int, enabled: bool) -> None:
Parameters
result_item_types A bitwise OR combination of one or more values from the EnumCapturedResultItemType enumeration.
enabled Set whether to enable result result deduplication.
See Also
is_result_deduplication_enabled
Determines whether the result deduplication feature is enabled for the specific result item type.
def is_result_deduplication_enabled(self, type: int) -> bool:
Parameters
type The specific captured result item type. It is a value from the EnumCapturedResultItemType enumeration.
Return Value
Returns a bool value indicating whether result deduplication is enabled for the specific result item type.
See Also
set_duplicate_forget_time
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 if deduplication feature is enabled. The default value is 3000ms.
def set_duplicate_forget_time(self, result_item_types: int, time: int) -> None:
Parameters
result_item_types A bitwise OR combination of one or more values from the EnumCapturedResultItemType enumeration.
time The duplicate forget time measured in milliseconds. The value rang is [1, 180000].
See Also
get_duplicate_forget_time
Gets the duplicate forget time for a specific captured result item type.
def get_duplicate_forget_time(self, type: int) -> int:
Parameters
type The specific captured result item type. It is a value from the EnumCapturedResultItemType enumeration.
Return Value
Returns the duplicate forget time for the specific captured result item type.

set_max_overlapping_frames
Sets the max referencing frames count for the to-the-latest overlapping feature.
def set_max_overlapping_frames(self, result_item_types: int, max_overlapping_frames: int) -> None:
Parameters
[in] result_item_types The or value of the captured result item types.
[in] max_overlapping_frames The max referencing frames count for the to-the-latest overlapping feature.
See Also
get_max_overlapping_frames
Gets the max referencing frames count for the to-the-latest overlapping feature.
def get_max_overlapping_frames(self, type: int) -> int:
Parameters
[in] type Specifies a specific result item type, which can be defined using EnumCapturedResultItemType.
Return value
Returns the max referencing frames count for the to-the-latest overlapping feature.
See Also
enable_latest_overlapping
