raptor-vision 1.1.0

Semantic Patch Analysis using DINOv3

RaptorVision

RaptorVision is an open-source tool developed by Rémi Pérenne, built upon Meta's DINOv3 foundation models. It allows anyone to create a custom object detection model with just a few clicks, requiring only a handful of example images.

Why RaptorVision?

This project was born from a specific need in biology: sorting through thousands of images from wildlife camera traps. While excellent tools like MegaDetector exist, they are often based on the YOLO architecture, which requires thousands of annotated images to recognize a specific species. This makes them difficult to use for rare species where data is scarce.

RaptorVision changes the game by using "few-shot learning":

• Efficiency: Learns what your target looks like from just 1 or 2 clicks.
• Versatility: Works for animals or any specific entity.
• Speed: Drastically reduces the time spent manually sorting images that do not contain what you want.

The name is a nod to Meta's DINO model (Velociraptor is a dinosaur) and the fact that the software acts as a "predator" finding its prey (your data) within a sea of images.

Installation

RaptorVision is available on PyPI. You can install it using pip:

pip install raptor-vision

Model Weights Setup

Due to Meta's license agreement, the model weights cannot always be downloaded automatically. If the software fails to download them on the first run, follow these steps:

1. Visit the Meta DINO Download Page and fill out the form.
2. Download the Small, Base, or Large models (the Small version is sufficient for 90% of use cases).
3. You will obtain files named like:
   • dinov3_vits16_pretrain_lvd1689m-08c60483.pth (Small)
   • dinov3_vitb16_pretrain_lvd1689m-73cec8be.pth (Base)
   • dinov3_vitl16_pretrain_lvd1689m-8aa4cbdd.pth (Large)
4. Launch raptor-vision. If the models are missing, the terminal will display the specific Torch cache path on your system.
5. Copy your downloaded .pth files into that directory and restart the application.

Examples & Performance

1. Point-and-Detect

Simply click on an object (e.g., a frog) to teach the model. The left panel shows the reference selection:

Select one bird...

...and RaptorVision automatically detects the others in subsequent frames:

Note: The top-right window shows which memory image the model is currently using for detection.

2. Complex Scenarios

RaptorVision handles visual diversity well. By clicking on a lizard, the model successfully identifies other lizards and even a snake in the same environment.

Tip: If the model is too sensitive (e.g., picking up a snake when you only want lizards), you can easily adjust the sensitivity threshold in the UI.

3. RaptorScan (Batch Processing)

For large datasets, RaptorVision generates detection heatmaps and automates file management.

RaptorScan Interface: You can process entire folders, automatically copy images containing detections to a new folder, and export detailed statistics (CSV/TXT) for analysis in Python or Excel.
