Initializing

This API is used to construct a hard example filter.

• API calling

  hilens.HardSample(threshold_one, threshold_two, filter_type)

• Parameter description

  Table 1 Parameters

  Parameter	Mandatory	Type	Description
  threshold_one	Yes	float	Threshold. The value varies depending on the value of filter_type.
  threshold_two	Yes	float	Threshold. The value varies depending on the value of filter_type.
  filter_type	Yes	int	Type of a hard example filter. Possible values are 0, 1, and 2, which correspond to CrossEntropyFilter, IBT, and CSF, respectively. For details, see Introduction to Hard Example Upload. If the value is 0, threshold_one corresponds to threshold_cross_entropy of CrossEntropyFilter, and threshold_two can be any value. If the value is 1, threshold_one and threshold_two correspond to box_threshold and img_threshold of IBT, respectively. If the value is 2, threshold_one and threshold_two correspond to box_threshold_low and box_threshold_up of CSF, respectively.

• Return value

  A hard example filter. If the construction fails, an exception is thrown.
