Setting this to ```true``` will tell Marty to advertise these topics and vice-versa.\n\nThe next three define the classifier to use when attempting to detect a certain feature. Bundled in the package within ```.../classifiers``` are a selection of some pre-made open source classifiers. Creating your own is possible, though outwith the scope of this package. To change the classifier, simply change the filename defined within these parameters.\n\nThis ```launch``` file also loads a separate parameter file, ```detection_params.yaml```, which defines the parameters used within the package's feature detection methods. Take a look at the comments within this file for further clarification.\n\nTopics\n===\n\n### Publishers:\n\n\tVideo:\n\n    /marty/face_tracking/faces\n    /marty/face_tracking/smiles\n    /marty/face_tracking/eyes\n\n    Co-ordinates:\n\n    /marty/face_tracking/faces_centroid\n    /marty/face_tracking/smiles_centroid\n    /marty/face_tracking/eyes_centroid\n\nThe format of the co-ordinate message are three x-y-z arrays of floats, defining the centroid co-ordinate of detected features.\n\n\tfloat32[] x\n\tfloat32[] y\n    float32[] z\n\nFor example, the co-ordinates of the first face would be at ```x[0]```, ```y[0]```, ```z[0]``` and so on.\n\nThis is defined within ```CentroidMsg.msg```, within the [marty_msgs](https://github.com/robotical/marty_msgs) package.\n\n### Subscribers:\n\n\t/marty/camera/image  \n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frobotical%2Fmarty_face_tracker","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frobotical%2Fmarty_face_tracker","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frobotical%2Fmarty_face_tracker/lists"}
