Package de.swa.fuh.yolo

Class YoloObjectDetection

java.lang.Object
de.swa.fuh.yolo.YoloObjectDetection
All Implemented Interfaces:
GMAF_Plugin
public class YoloObjectDetection
extends java.lang.Object
implements GMAF_Plugin
This Class acts as a Plugin to implement object recognition, using the YOLOv3 convolutional neural network, into the GMAF Framework. Prerequisites for the usage of the Plugin (as detailed in installation.pdf) are: - An installation of the OpenCV 4.52 Library on the using machine - Inclusion of the OpenCV 4.52 Library into the GMAF Project Buildpath - Folder /yolo/ containing provided yolo_class.names, yolo.cfg and yolo.weights files - de.fuh.fpss21.group4.YoloObjectDetection added to GMAF plugin.config

  • Method Summary

    Modifier and Type Method Description
    boolean canProcess​(java.lang.String arg0)
    this method returns, if the plugin is able to process files with a given extension
    java.util.Vector<Node> getDetectedNodes()
    this method is called by the GMAF to receive the results of this plugin and to fuse it into the MMFG
    boolean isGeneralPlugin()
    if this plugin contains overall metadata, e.g.
    void process​(java.net.URL url, java.io.File f, byte[] bytes, MMFG fv)
    An implementation of GMAF_Plugin process method for use with the YOLOv3 CNN.
    boolean providesRecoursiveData()
    this method should indicate, if it returns recursive data, which are then re-processed within the GMAF framework

    • canProcess

      public boolean canProcess​(java.lang.String arg0)
      Description copied from interface: GMAF_Plugin
      this method returns, if the plugin is able to process files with a given extension
      Specified by:
      canProcess in interface GMAF_Plugin
      Returns:
      true or false

    • providesRecoursiveData

      public boolean providesRecoursiveData()
      Description copied from interface: GMAF_Plugin
      this method should indicate, if it returns recursive data, which are then re-processed within the GMAF framework
      Specified by:
      providesRecoursiveData in interface GMAF_Plugin
      Returns:
      true, if recursive data is available

    • isGeneralPlugin

      public boolean isGeneralPlugin()
      Description copied from interface: GMAF_Plugin
      if this plugin contains overall metadata, e.g. EXIF data, this method should return true to indicate, that these general data have to be attached to the MMFG's root node
      Specified by:
      isGeneralPlugin in interface GMAF_Plugin
      Returns:
      true, if it is a general plugin

    • getDetectedNodes

      public java.util.Vector<Node> getDetectedNodes()
      Description copied from interface: GMAF_Plugin
      this method is called by the GMAF to receive the results of this plugin and to fuse it into the MMFG
      Specified by:
      getDetectedNodes in interface GMAF_Plugin
      Returns:
      a vector of MMFG nodes

    • process

      public void process​(java.net.URL url, java.io.File f, byte[] bytes, MMFG fv)
      An implementation of GMAF_Plugin process method for use with the YOLOv3 CNN.
      Specified by:
      process in interface GMAF_Plugin
      Parameters:
      fv - Prepared feature vector which is passed from the GMAF Framework. Found child nodes will be attached here
      f - Pointer to the image file. Required! Only way to pass an image to the plugin in this implementation
      url - This way of passing an image file is not supported by the implementation and will result in 0 objects found
      bytes - This way of passing an image file is not supported by the implementation and will result in 0 objects found
