| - | ---- | + | ===== labelImg ===== |
| - | === Setup === | + | |
| - | In order to tag images, we use a piece of software called Sloth. To install it from the robosub debian repository, run the following command: | + | |
| - | sudo aptitude install sloth | + | For complete details on using labelImg, see [[https://github.com/tzutalin/labelImg]]. |
| - | ---- | + | We use labelImg to tag objects in images. labelImg can be installed with pip with the command ''pip3 install labelImg''. Once installed you can run ''labelImg'' from a terminal. When running labelImg with no arguments, you will have to use the labelImg interface to select and image or directory to open, and you will need to type in labels manually. Because of this it can be more efficient to run labelImg with image_directory and predefined_classes arguments. If you have a dataset with images in a directory called ''images'' and a label file called ''labels.txt'', you can run labelImg as shown below to open the image directory and have a list of labels to select from: |
| - | === Using Sloth === | + | |
| - | To use sloth and start tagging images, you can run the following command. | + | |
| - | + | ||
| - | sloth -c /path/to/vision_dev/sloth/robosub_config.py /path/to/annotation/file | + | |
| - | + | ||
| - | *-c* Is a flag to give the path to a configuration file. This file is provided in the vision_dev/sloth directory. The path you provide should point to this file. | + | |
| - | + | ||
| - | The last argument is a path to an annotation file. This is most likely named something like `labels.json`. You will need to provide this path in order to tag images. | + | |
| - | + | ||
| - | Should you find this tedious, there is a script in the sloth directory of the vision_dev repository which performs some of this for you. It can be used as follows: | + | |
| - | + | ||
| - | ./robosub_sloth.sh /path/to/annotation/file | + | |
| - | + | ||
| - | This removes the need to add the -c flag repeatedly. This script can also be symlinked to without issues. | + | |

| - | The full list of keybindings used in sloth can be found in the [[https://github.com/PalouseRobosub/vision_dev/blob/master/sloth/robosub_config.py|robosub_config.py]] file near the bottom. A shorthand list is provided below | + | |
