setInputSize((int, int) inputSize) → void
Set the size for the network input, which overwrites the input size of creating model. Call this method when the size of input image does not match the input size when creating model.
setInputSizeAsync((int, int) inputSize) → Future<void>

Available on FaceDetectorYN, provided by the FaceDetectorYNAsync extension

setNMSThreshold(double nmsThreshold) → void
Set the Non-maximum-suppression threshold to suppress bounding boxes that have IoU greater than the given value.
setNMSThresholdAsync(double nmsThreshold) → Future<void>

Available on FaceDetectorYN, provided by the FaceDetectorYNAsync extension

setScoreThreshold(double scoreThreshold) → void
Set the score threshold to filter out bounding boxes of score less than the given value.
setScoreThresholdAsync(double scoreThreshold) → Future<void>

setTopK(int topK) → void
Set the number of bounding boxes preserved before NMS.
