func (d *Detector) Close()

func (*Detector) DetectNextFrame ¶

func (d *Detector) DetectNextFrame(camIndex int) (*frame.FrameDetectResult, error)

func (*Detector) ParseResult ¶

func (d *Detector) ParseResult(data []byte) ([]*frame.Box, error)

a. First fp16 value holds the number of valid detections = num_valid. b. The next 6 values are unused. c. The next (7 * num_valid) values contain the valid detections data

Each group of 7 values will describe an object/box These 7 values in order.
The values are:
  0: image_id (always 0)
  1: class_id (this is an index into labels)
  2: score (this is the probability for the class)
  3: box left location within image as number between 0.0 and 1.0
  4: box top location within image as number between 0.0 and 1.0
  5: box right location within image as number between 0.0 and 1.0
  6: box bottom location within image as number between 0.0 and 1.0
