Quick Overview

https://github.com/SysCV/nutsh/assets/1113875/55925677-57ff-4870-b853-d67c80517eb7

Diverse Annotations and Versatile Scenarios

Drawing Polygons

In addition to standard polygon operations, Bézier curves are supported, enabling precise annotations of curved objects, such as tires.

Drawing masks

Create masks with pixel-level accuracy, ensuring a perfect fit with no gaps or overlaps.

Tracking Objects

Especially useful when annotating videos, the platform offers an effortless way to track objects across frames.

Linking Object Parts

Objects obscured by others, resulting in fragmented representation, can easily be linked to form a cohesive annotation

Convenient Shortcuts

The platform incorporates various shortcuts, streamlining the annotation process for enhanced speed and accuracy.

Cloning Slice

For polygons sharing a common edge segment, one can be cloned for the other, ensuring a seamless fit without any gaps or overlaps.

https://github.com/SysCV/nutsh/assets/1113875/b13ebac0-921d-4ad4-96fb-9bc33669143c

Interpolation

Given two annotations of the same type on both a start and an end frame, heuristic interpolation can automatically generate all intermediate annotations.

Model-Assisted Segmentation

We offer an API that seamlessly integrates the human labeling interface with deep learning models. Our server facilitates model inference and tuning based on user input. Calculations can be executed on both CPU and GPU platforms.

For instance, our SAM module taps into the Segment Anything Model from Meta AI to enhance segmentation speed and efficiency. While the SAM models are openly accessible to the public, their labeling interface remains proprietary. We also offer advanced features, such as local prediction, to ensure top-notch segmentation results. For a detailed guide, please refer to our documentation.

Global Smart Segmentation

Leverage deep learning models to perform segmentation tasks across entire images, aiding the segmentation process.

https://github.com/SysCV/nutsh/assets/1113875/c64913d8-6422-40b4-bb4b-8e35f86f9af1

Local Smart Segmentation

Direct your attention to specific regions of an image and request the model to generate segmentation predictions for that particular section. Such localized predictions often yield more detailed segmentations.

https://github.com/SysCV/nutsh/assets/1113875/b486d6ac-a462-4d6b-aecd-d992055855a9

Learning from Human Feedback

In addition to utilizing prompts for refining predictions, users can make subsequent adjustments to these predictions. By gathering these modifications, you can train a model that's fine-tuned to your specific needs. Our SAM module comes equipped with features that assist in fine-tuning the SAM decoder seamlessly.

Custom Model Integration

Nutsh offers a Python SDK, enabling the quick and easy integration of your custom models in Python into the platform. Additionally, our gRPC interfaces are available for a more low-level but flexible approach to integrating your ideas. As an example, check the auto-tracking feature for videos to see how integrated tracking models can enhance your annotation workflows.
