๐Ÿš€ CoMotion: Concurrent Multi-person 3D Motion ๐Ÿšถโ€โ™‚๏ธ๐Ÿšถโ€โ™€๏ธ

Introducing CoMotion, a project that detects and tracks detailed 3D poses of multiple people using a single monocular camera stream. This system maintains temporally coherent predictions in crowded scenes filled with difficult poses and occlusions, enabling online tracking through frames with high accuracy.

๐Ÿ” Key Features:
- Precise detection and tracking in crowded scenes
- Temporal coherence even with occlusions
- High accuracy in tracking multiple people over time

๐ŸŽ‰๐Ÿš Introducing Unidrone v1.0 โ€“ The Next Generation of Aerial Object Detection Models ๐Ÿš๐ŸŽ‰

We are excited to present Unidrone v1.0, a powerful collection of AI detection models based on YOLOv8, specially designed for object recognition in drone imagery.

๐Ÿ” What is Unidrone?
Unidrone is a smart fusion of two previous models: WALDO (optimized for nadir/overhead views) and NANO (designed for forward-looking angles). Now you no longer need to choose between themโ€”Unidrone handles both angles with high accuracy!

๐Ÿ“ฆ These models accurately detect objects in drone images taken from altitudes of approximately 50 to 1000 feet, regardless of camera angle.

๐Ÿ” Supported Object Classes:0๏ธโƒฃ Person (walking, biking, swimming, skiing, etc.)

1๏ธโƒฃ Bike & motorcycle
2๏ธโƒฃ Light vehicles (cars, vans, ambulances, etc.)
3๏ธโƒฃ Trucks
4๏ธโƒฃ Bus
5๏ธโƒฃ Boat & floating objects
6๏ธโƒฃ Construction vehicles (e.g., tractors, loaders)

๐Ÿšซ Note: This version of Unidrone does not include military-related classes or smoke detection. It's built solely for civilian and safety-focused applications.

๐Ÿ“Œ Use Cases:โœ… Disaster recovery operations

โœ… Wildlife and protected area monitoring
โœ… Occupancy analysis (e.g., parking lots)
โœ… Infrastructure surveillance
โœ… Search and rescue (SAR)
โœ… Crowd counting
โœ… Ground-risk mitigation for drones

๐Ÿ› ๏ธ The models are available in .pt format and can easily be exported to ONNX or TFLite. They also support visualization with Roboflowโ€™s Supervision library for clean, annotated outputs.

๐Ÿง  If you're a machine learning practitioner, you can:


Fine-tune the models on your own dataset


Optimize for fast inference on edge devices


Quantize and deploy on low-cost hardware


Use the models to auto-label your own data


๐Ÿ“จ If you're facing detection issues or want to contribute to future improvements, feel free to contact the developer:
[email protected]
Enjoy exploring the power of Unidrone v1.0!

๐Ÿš€ Retail Fashion Sales Data Analysis

Here's a fascinating project in the field of data analysis, focused on real-world fashion retail sales. The dataset contains 3,400 records of customer purchases, including item types, purchase amounts, customer ratings, and payment methods.

๐Ÿ” Project Goals:
- Understand customer purchasing behavior
- Identify the most popular products
- Analyze preferred payment methods

๐Ÿ“Š The dataset was first cleaned using Pandas to handle missing values, and then insightful visualizations were created with Matplotlib to reveal hidden patterns in the data.

๐Ÿ”—Data source: https://lnkd.in/dbGbuhG7

๐Ÿš€ The new HQ-SAM (High-Quality Segment Anything Model) has just been added to the Hugging Face Transformers library!

This is an enhanced version of the original SAM (Segment Anything Model) introduced by Meta in 2023. HQ-SAM significantly improves the segmentation of fine and detailed objects, while preserving all the powerful features of SAM โ€” including prompt-based interaction, fast inference, and strong zero-shot performance. That means you can easily switch to HQ-SAM wherever you used SAM!

The improvements come from just a few additional learnable parameters. The authors collected a high-quality dataset with 44,000 fine-grained masks from various sources, and impressively trained the model in just 4 hours using 8 GPUs โ€” all while keeping the core SAM weights frozen.

The newly introduced parameters include:

* A High-Quality Token
* A Global-Local Feature Fusion mechanism

This work was presented at NeurIPS 2023 and still holds state-of-the-art performance in zero-shot segmentation on the SGinW benchmark.

๐Ÿ”ฅPowerful Combo: Ultralytics YOLO11 + Sony Semicon | AITRIOS (Global) Platform + Raspberry Pi
Weโ€™ve recently updated our Sony IMX model export to fully support YOLO11n detection models! This means you can now seamlessly run YOLO11n models directly on Raspberry Pi AI Cameras powered by the Sony IMX500 sensor โ€” making it even easier to develop advanced Edge AI applications. ๐Ÿ’ก
To test this new export workflow, I trained a model on the VisDrone dataset and exported it using the following command:
๐Ÿ‘‰
yolo export model=<path_to_drone_model> format=imx data=VisDrone.yaml
๐ŸŽฅ The video below shows the result of this process!
๐Ÿ”Benchmark results for YOLO11n on IMX500:โœ… Inference Time: 62.50 msโœ… mAP50-95 (B): 0.644๐Ÿ“Œ Want to learn more about YOLO11 and Sony IMX500? Check it out here โžก๏ธ
