Method Detail

optClip

public MultiBoxDetection.Builder optClip(boolean clip)

Sets the boolean parameter that indicates whether to clip out-of-boundary boxes. It is set to true by default.

Parameters:

clip - whether to clip out-of-boundary boxes

Returns:

this Builder

optForceSuppress

public MultiBoxDetection.Builder optForceSuppress(boolean forceSuppress)

Sets the boolean parameter that indicates whether to suppress all detections regardless of class_id. It is set to false by default.

Parameters:

forceSuppress - whether to suppress all detections regardless of class_id

Returns:

this Builder

optBackgroundId

public MultiBoxDetection.Builder optBackgroundId(int backgroundId)

Sets the class ID for the background. Defaults to 0.

Parameters:

backgroundId - the class ID for the background

Returns:

this Builder

optNmsTopK

public MultiBoxDetection.Builder optNmsTopK(int nmsTopK)

Sets the boolean parameter that indicates whether to clip out-of-boundary boxes. Defaults to -1 which implies that there is no limit.

Parameters:

nmsTopK - whether to clip out-of-boundary boxes

Returns:

this Builder

optThreshold

public MultiBoxDetection.Builder optThreshold(float threshold)

Sets the threshold score for a detection to be a positive prediction. Defaults to 0.01.

Parameters:

threshold - the threshold score for a detection to be a positive prediction

Returns:

this Builder

optNmsThreshold

public MultiBoxDetection.Builder optNmsThreshold(float nmsThreshold)

Sets the non-maximum suppression(NMS) threshold. Defaults to 0.5.

Parameters:

nmsThreshold - the non-maximum suppression(NMS) threshold

Returns:

this Builder

build

public MultiBoxDetection build()

Builds a MultiBoxDetection block.

Returns:

the MultiBoxDetection block
