Member Function Documentation

add()

None add	(		self,
		str	label,
		cvb.Image	src_image,
		cvb.Point2D	extraction_location,
		Optional[int]	mode
	)

Add a sample to a new class.

If the class indicated by the label already exists the sample will be added to the existing class.

Parameters

label : str Name of the new class.

src_image : cvb.Image Image from which to extract the first sample for the new class.

extraction_location : cvb.Point2D Location at which to extract the first sample for the new class. Note that what the extraction location actually refers dependent on the value of the mode parameter.

mode : Optional[int] Interpretation hint for the extraction_location parameter (see cvb.sample_database.SampleExtractionMode).

clear()

None clear

(

self

)

Remove all labels (and their associated data) from the sample list.

Note that this invalidates all info objects that have been taken from this collection!

has_label()

None has_label	(		self,
		str	label
	)

Check if a given label is already present in the classes collection.

Parameters

label : str Label to test for.

merge_classes()

None merge_classes	(		self,
		str	from_label,
		str	to_label
	)

Merge two classes into one class.

Parameters

from_label : str Class to merge to the other classes.

to_label : str Class to merge the samples to.

merge_classes_by_index()

None merge_classes_by_index	(		self,
		int	from_index,
		int	to_index
	)

Merge two classes into one class.

The class label will be taken from the 2nd class index. Note that this operation will invalidate all indices higher than from_index.

Parameters

from_index : int Class to merge to the other classes.

to_index : int Class to merge the samples to.

read_info()

cvb.sample_database.ImageClassificationLabelInfo read_info	(		self,
		int	index
	)

Retrieves the indexed item.

Parameters

index : int Index of the collection to be accessed.

Returns

cvb.sample_database.ImageClassificationLabelInfo Label information.

read_infos()

List[cvb.sample_database.ImageClassificationLabelInfo] read_infos

(

self

)

Retrieves all the items stored in the collection.

Returns

List[cvb.sample_database.ImageClassificationLabelInfo] The collection items.

remove()

None remove	(		self,
		str	label
	)

Remove a class and all the data objects associated with it based on its name.

Parameters

label : str Name of the new class to be removed.

remove_at()

None remove_at	(		self,
		int	index
	)

Remove a class by index.

Parameters

index : int Index of the class to be removed.
