Versatile Annotation
picA
supports a variety of annotation tasks, allowing you to seamlessly annotate images for different purposes, from simple object counting to complex instance and semantic segmentation. -
Deep Learning Integration
Harness the capabilities of deep learning models to enhance your annotation process.
picA
supports integration with pre-trained models, enabling you to accelerate and improve annotation accuracy. -
Custom Model Deployment [TBD]
Utilize your own custom deep learning models within
picA
. Tailor your annotations to your project's unique requirements, ensuring precise and reliable results. -
Export in COCO Format
Easily export your annotations in the COCO (Common Objects in Context) format, a widely used standard in the computer vision community. Your annotated data is ready for integration into your machine learning pipeline.
- COCO format annotations export.
- Category visibility control.
- Customized model integration.
- Nested category supports.
- Keypoint annotation supports.
- Rotated bounding box annotation supports.
See below for a quickstart installation or it's recommended to directly pulling a docker file.
Pip installation need Python>=3.8 and requirements below:
- Python >= 3.8
- pip >= 22.0
- PyTorch >= 1.10
cd /path/to/picA
pip install -r requirements.txt
TBD.
picA
may be launched directly in the Command Line Interface (CLI):
cd /path/to/picA
python main.py
To create a new project, click File -> New Project
to select a folder that contains image data. PicA officially supports jpg
, jpeg
, png
, and bmp
image formats.
Project Name
|--- image01.jpg
|--- image02.jpg
|--- ...
The project will be saved in the selected foler and the results look like:
Project Name
|--- image01.jpg
|--- image02.jpg
|--- ...
|--- annotations
|.. |--- annotations.json
|.. |--- masks
|.. |--- color_masks
|.. |.. |--- image01.png
|.. |.. |--- image02.png
|.. |.. |--- ...
When importing an existing project with File -> Import Project
, ensure that you select the Project Name
folder and verify that all images and annotations are located within the same Project Name
directory.
If creating or importing a project encounters issues, a simple solution is to relaunch the application.
Annotation integration is also available. Upon opening the Project 1 window, you can opt to Import Project
to merge Project 2 with the existing one. However, please exercise caution and consider the following guidelines:
- Merging is supported only for projects with the same annotation tasks.
- Ensure that all images are situated within the directory of the Project 1.
- In cases of conflicts, such as annotations on the same image in both projects, picA will prioritize retaining annotations from Project 1.
All annotations will be preserved within the context of the Project 1, providing a consolidated and organized annotation repository.
In picA
, interactions can be categorized into two distinct operations: File or Category Selection and Annotation Manipulation.
This operation is accessible through the side panel. Here, users can seamlessly navigate between different files and efficiently manage categories. Within this panel, you have the capability to create, delete, and modify categories. Additionally, the ability to create instances offers for Instance and Panoptic Segmentation.
Found at the bottom panel, this operation encompasses the core of annotation activities. It's divided into two primary modes: Select
and Draw
. The Select
mode empowers users to highlight, modify, and delete existing annotations, as well as reassign them to different categories. On the other hand, the Draw
mode employs distinct terminology tailored to specific annotation tasks, such as Click
, Rectangle
, and Polygon
.
Under Smart Annotation
menu, picA
supports Superpixel
and AI model
two ways to help the annotation tasks (Superpixel
only supports segmentation tasks.). By checking either options, action buttons will appear at the botton panel.
picA
officially supports annotation tasks for Obejct Counting, Object Detection, Instance Segmentation, Semantic Segmentation and Panoptic Segmentation.
At present, picA
does not feature an autosave function. Users are required to save their projects manually, and the progress will also be automatically saved upon exiting picA
.
