'Genuine' field

In TrackedObject we have a Genuine field. This is an attempt at reducing false positives from the NN. We should aim to get rid of this kind of filtering, and rely solely on the neural network. End to end is always the goal!

Types ¶

type AnalysisState ¶

type AnalysisState struct {
	CameraID int64               `json:"cameraID"`
	Input    *nn.DetectionResult `json:"input"`
	Objects  []TrackedObject     `json:"objects"`
}

Result of post-process analysis on the Object Detection neural network output SYNC-ANALYSIS-STATE

type Monitor ¶

type Monitor struct {
	Log log.Log
	// contains filtered or unexported fields
}

func NewMonitor ¶

func NewMonitor(logger log.Log) (*Monitor, error)

func (*Monitor) AddWatcher ¶

func (m *Monitor) AddWatcher(cameraID int64) chan *AnalysisState

Register to receive detection results for a specific camera. You must be careful to ensure that your receiver always processes a result immediately, and keeps the channel drained. If you don't do this, then the monitor will freeze, and obviously that's a really bad thing to happen to a security system.

func (*Monitor) AddWatcherAllCameras ¶

func (m *Monitor) AddWatcherAllCameras() chan *AnalysisState

Add a watcher that is interested in all camera activity

func (*Monitor) AllClasses ¶

func (m *Monitor) AllClasses() []string

Return the list of all classes that the NN detects

func (*Monitor) Close ¶

func (m *Monitor) Close()

Close the monitor object.

func (*Monitor) DetectedClasses ¶

func (m *Monitor) DetectedClasses() []string

Return the list of classes that we're interested in

func (*Monitor) LatestFrame ¶

func (m *Monitor) LatestFrame(cameraID int64) (*cimg.Image, *nn.DetectionResult, *AnalysisState, error)

Return the most recent frame and detection result for a camera

func (*Monitor) RemoveWatcher ¶

func (m *Monitor) RemoveWatcher(cameraID int64, ch chan *AnalysisState)

Unregister from detection results for a specific camera

func (*Monitor) RemoveWatcherAllCameras ¶

func (m *Monitor) RemoveWatcherAllCameras(ch chan *AnalysisState)

Unregister from detection results of all cameras

func (*Monitor) SetCameras ¶

func (m *Monitor) SetCameras(cameras []*camera.Camera)

Set cameras and start monitoring

type TrackedObject ¶

type TrackedObject struct {
	ID      uint32  `json:"id"`
	Class   int     `json:"class"`
	Box     nn.Rect `json:"box"`
	Genuine bool    `json:"genuine"`
}

An object that was detected by the Object Detector, and is now being tracked by a post-process SYNC-TRACKED-OBJECT
