    • loadOpenCV

      public static void loadOpenCV()
      Load OpenCV native library.

    • loadResourceLocation

      public void loadResourceLocation()
      Get the absolute path of the src/main/resources folder and save it in mAbsolutePath.

    • loadModel

      public void loadModel()
      Loads the model yolov3 as the neuronal network to use.

    • loadImageFromPath

      public void loadImageFromPath​(java.lang.String path)
      Loading the image in the working data class of OpenCV.
      Parameters:
      path - Path to the image file.

    • addDetectionsToNode

      public void addDetectionsToNode​(MMFG fv, java.util.Vector<Node> detectedNodes, float confThreshold)
      Generates the detections of the model. The nodes contains the classification name specified in cocoNames and the position in the TechnicalAttribute.
      Parameters:
      fv - holds the node where to save the detections.
      detectedNodes - also save the nodes in this vector to make it compatible with the interface of GMAF_Plugin.
      confThreshold - sets the threshold which evaluates of a detection is enough sure.
