PM> Install-Package matrix-io-malos

Using the MalosDriver

To use the MALOS driver in your code you can do the following:

class Program
    static matrix_io_malos.Driver driver;

    static void Main(string[] args)
        // Initialize the driver for malos vision with the IP and the BasePort.
        driver = new matrix_io_malos.Driver("", matrix_io_malos.BasePort.Vision);

        // Add the event handler to receive the data events.
        driver.onGetData += Driver_onGetData;

        // Start the connection to get the data events from Malos Vision.

    private static void Driver_onGetData(byte[] data)
        // Parse the date from byte array to a vision result object.
        MatrixIO.Vision.V1.VisionResult result;
        result = MatrixIO.Vision.V1.VisionResult.Parser.ParseFrom(data);

        // Convert the vision result to a json.
        var json = Google.Protobuf.JsonFormatter.Default.Format(result);

    private static void stopGetData()
        // Stop the connection to get data from Malos Vision.

MALOS Vision data

On each onGetData event you will receive a byte array data that you can parse to a VisionResult object. if you convert the VisionResult to a Json you will have an object like the follow

    "rectDetection": [{
        "facialRecognition": [{

This message organizes (at least) four components: - Detections (faces, hands, cars). - Tracking information. - Recognition (gender, age, emotion). - Events (New face in video, face leaves video, gesture starts).

  • rectDetection Results of all the rectangular detectors. Each detecion also stores the recognitions that can be done inside of this rectangle. For instance, for faces the available recognitions are (age, gender, emotion).
  • visionEvent Vision events. For instance, tracking events (start, end). This message is not inside rect_detection because some events will happen when the detection is no longer available, for instance: TRACKING_END.
  • uuid UUID (v4) that uniquely identifies each vision result


Result of a rectangle detector.

  • facialRecognition Facial recognitions for this detection (age, gender, pose, features, etc).
  • tag What kind of detections the rectangle contains.
  • trackingId Tracking id for this detection.
  • uuid UUID (v4) identifies this unique rectangular detection


The following fields should only be present when the tag HAS_AGE tag is set.

  • age Detected age.

The following fields should only be present when the tag HAS_GENDER is set.

  • gender Detected gender, genders available for detections are MALE, FEAMLE.

The following fields should only be present when the tag HAS_EMOTION is set.

  • emotion Detected emotion, emotions available for detections are ANGRY, DISGUST, CONFUSED, HAPPY, SAD, SURPRISED, CALM, FEAR, NEUTRAL.

The following fields should only be present when the tag HAS_HEAD_POSE is set.

  • poseYaw Face yaw.
  • poseRoll Face roll.
  • posePitch Face pitch.
  • isLooking Face looking.


  • tag Tag for events. The fields below will make sense for a specific tag. for face will be TRACKING_START or TRACKING_END
  • trackingId Object identifier.
  • dwellTime Dwell time: Amount of seconds facing the camera. Used for TRACKING_END event.
