Using Annotation GUI

Directory Structure for Data

• training_data node is the ROS node which is supposed to contain all the training data.
• Folder training_data/preTrainData contains data collected for pre-training phase.
• This folder should have these 5 sub-folders-
  • Annotations (can be a soft link to another drive e.g., /mnt/theakston/srvcData09/Annotations)
  • Images (can be a soft link to another drive e.g., /mnt/theakston/srvcData09/data/Images)
  • tmp
  • DPMcache
  • ImageSets (this folder stores files with list of training/test images)

Running Annotator

• Annotator can be launched using the command- $roslaunch DPM Annotation.launch

• Once the GUI is visible. Go- File>open and choose the directory where data is stored
• Draw a bounding box by click and drag, press save and next(this actually saves the file)
• To Annotate multiple objects in the same image, press save after drawing a box and then draw another bounding box.
