| ## [LabelMe](https://github.com/wkentaro/labelme) | |
| ### Instruction of LabelMe | |
| #### Installation | |
| Please refer to [The github of LabelMe](https://github.com/wkentaro/labelme) for installation details. | |
| <details> | |
| <summary><b> Ubuntu</b></summary> | |
| ``` | |
| sudo apt-get install labelme | |
| # or | |
| sudo pip3 install labelme | |
| # or install standalone executable from: | |
| # https://github.com/wkentaro/labelme/releases | |
| ``` | |
| </details> | |
| <details> | |
| <summary><b> macOS</b></summary> | |
| ``` | |
| brew install pyqt # maybe pyqt5 | |
| pip install labelme | |
| # or | |
| brew install wkentaro/labelme/labelme # command line interface | |
| # brew install --cask wkentaro/labelme/labelme # app | |
| # or install standalone executable/app from: | |
| # https://github.com/wkentaro/labelme/releases | |
| ``` | |
| </details> | |
| We recommend installing by Anoncanda. | |
| ``` | |
| conda create โname=labelme python=3 | |
| conda activate labelme | |
| pip install pyqt5 | |
| pip install labelme | |
| ``` | |
| #### Annotation of Images in LabelMe | |
| After starting labelme, select an image or an folder with images. | |
| Select `create polygons` in the formula bar. Draw an annotation area as shown in the following GIF. You can right-click on the image to select different shape. When finished, press the Enter/Return key, then fill the corresponding label in the popup box, such as, people. | |
| Click the save button in the formula bar๏ผit will generate an annotation file in json. | |
|  | |
| ### Annotation Format of LabelMe | |
| #### Export Format of LabelMe | |
| ``` | |
| #generate an annotation file | |
| png/jpeg/jpg-->labelme-->json | |
| ``` | |
| #### Summary of Format Conversion | |
| ``` | |
| #convert annotation file to VOC dataset format | |
| json-->labelme2voc.py-->VOC dataset | |
| #convert annotation file to COCO dataset format | |
| json-->labelme2coco.py-->COCO dataset | |
| ``` | |
| #### Annotation file(json)โ>VOC Dataset | |
| Use this script [labelme2voc.py](https://github.com/wkentaro/labelme/blob/main/examples/bbox_detection/labelme2voc.py) in command line. | |
| ```Te | |
| python labelme2voc.py data_annotated(annotation folder) data_dataset_voc(output folder) --labels labels.txt | |
| ``` | |
| Then, it will generate following contents: | |
| ``` | |
| # It generates: | |
| # - data_dataset_voc/JPEGImages | |
| # - data_dataset_voc/Annotations | |
| # - data_dataset_voc/AnnotationsVisualization | |
| ``` | |
| #### Annotation file(json)โ>COCO Dataset | |
| Convert the data annotated by LabelMe to COCO dataset by the script [x2coco.py](https://github.com/PaddlePaddle/PaddleDetection/blob/release/2.6/tools/x2coco.py) provided by PaddleDetection. | |
| ```bash | |
| python tools/x2coco.py \ | |
| --dataset_type labelme \ | |
| --json_input_dir ./labelme_annos/ \ | |
| --image_input_dir ./labelme_imgs/ \ | |
| --output_dir ./cocome/ \ | |
| --train_proportion 0.8 \ | |
| --val_proportion 0.2 \ | |
| --test_proportion 0.0 | |
| ``` | |
| After the user dataset is converted to COCO data, the directory structure is as follows (Try to avoid use Chinese for the path name in case of errors caused by Chinese coding problems): | |
| ``` | |
| dataset/xxx/ | |
| โโโ annotations | |
| โ โโโ train.json # Annotation file of coco data | |
| โ โโโ valid.json # Annotation file of coco data | |
| โโโ images | |
| โ โโโ xxx1.jpg | |
| โ โโโ xxx2.jpg | |
| โ โโโ xxx3.jpg | |
| โ | ... | |
| ... | |
| ``` | |
| ## [LabelImg](https://github.com/tzutalin/labelImg) | |
| ### Instruction | |
| #### Installation of LabelImg | |
| Please refer to [The github of LabelImg](https://github.com/tzutalin/labelImg) for installation details. | |
| <details> | |
| <summary><b> Ubuntu</b></summary> | |
| ``` | |
| sudo apt-get install pyqt5-dev-tools | |
| sudo pip3 install -r requirements/requirements-linux-python3.txt | |
| make qt5py3 | |
| python3 labelImg.py | |
| python3 labelImg.py [IMAGE_PATH] [PRE-DEFINED CLASS FILE] | |
| ``` | |
| </details> | |
| <details> | |
| <summary><b>macOS</b></summary> | |
| ``` | |
| brew install qt # Install qt-5.x.x by Homebrew | |
| brew install libxml2 | |
| or using pip | |
| pip3 install pyqt5 lxml # Install qt and lxml by pip | |
| make qt5py3 | |
| python3 labelImg.py | |
| python3 labelImg.py [IMAGE_PATH] [PRE-DEFINED CLASS FILE] | |
| ``` | |
| </details> | |
| We recommend installing by Anoncanda. | |
| Download and go to the folder of [labelImg](https://github.com/tzutalin/labelImg#labelimg) | |
| ``` | |
| conda install pyqt=5 | |
| conda install -c anaconda lxml | |
| pyrcc5 -o libs/resources.py resources.qrc | |
| python labelImg.py | |
| python labelImg.py [IMAGE_PATH] [PRE-DEFINED CLASS FILE] | |
| ``` | |
| #### Installation Notes | |
| Use python scripts to startup LabelImg: `python labelImg.py <IMAGE_PATH>` | |
| #### Annotation of images in LabelImg | |
| After the startup of LabelImg, select an image or a folder with images. | |
| Select `Create RectBox` in the formula bar. Draw an annotation area as shown in the following GIF. When finished, select corresponding label in the popup box. Then save the annotated file in three forms: VOC/YOLO/CreateML. | |
|  | |
| ### Annotation Format of LabelImg | |
| #### Export Format of LabelImg | |
| ``` | |
| #generate annotation files | |
| png/jpeg/jpg-->labelImg-->xml/txt/json | |
| ``` | |
| #### Notes of Format Conversion | |
| **PaddleDetection supports the format of VOC or COCO.** The annotation file generated by LabelImg needs to be converted by VOC or COCO. You can refer to [PrepareDataSet](./PrepareDataSet.md#%E5%87%86%E5%A4%87%E8%AE%AD%E7%BB%83%E6%95%B0%E6%8D%AE). | |
