• data: It contains the dataset,
• pretrained: It contains the pretreined autoencoder models,
• src: It contains the encoding and decoding processes,
• heatmaps: It contains the output heatmaps for the single/multi search,
• lernr_map: It contains the lernr maps as dictionary,
• images: It contains the video generated by the navigation/querying,
• lernr: It contains utils files,
• evaluation.py: It performs an evaluation on the maps contained in the lernr_maps folder,
• map_creation.py: It generates lernr maps,
• query_map.py: It queries the maps on single or multi search.

Download lernr_map from here and put it in the lernr_map folder. To download the pretrained ckpt, download the ckpt from here and put them inside the pretrained folder.

• Example:

  python map_creation.py --scene="Wiconisco" --n_goals=25 --img_res=128 --map_size=128

• scene: Name of the scene (default: Cantwell)

• n_goals: Number of goal points to reach (default: 25)

• img_res: Input img resolution entering the encoder (default: 128)

• map_size: Lernr_map's resolution (default: 128)

• make_video: If present, a video of the navigation is generated (default: false)

• Outputs:

  • Single object search:
    • For each different word queries a heat map is saved.
  • Multi object search:
    • A heat map with different locations of the given query word is saved.

• Example

  • Single object search:
    • python query_map.py --scene="Wiconisco" --query_words="toilet, couch" --negative_prompt="objects, textures" --make_video --smooth
  • Multi object search:
    • python query_map.py --scene="Cantwell" --query_words="Window" --make_video --smooth --erased_area=500 --th=0.6 --multi_search

• scene: Name of the map (default: "Cantwell")

• query_words: Objects to search (default: "Window")

• negative_prompt: List of negative prompt (default: "stuff, things, objects, textures")

• make_video: If present a video of the navigation is generated (default: False)

• smooth: If present, the video generated is smooth (default: False)

• multi_object: if present, a multi object search is performed, otherwise a sigle object search is made

• erased_area: Area to delete, in order to perform multi object search (default: 500)

• th: Treshold used in the multi object search to stop the navigation (default: 0.6)
