Precise surgical video annotation – browser-based, AI-supported, ready to use.
Our Web Application Ecosystem for Image and Video Annotation, Analysis & AI (ImViA) for surgical video annotation simplifies the structured capture and analysis of complex surgical images – without local installation. Surgical procedures can be efficiently annotated, analyzed and processed for a variety of applications directly in the browser.
The full-stack web platform provides researchers and development teams with powerful tools for creating accurate training data for AI models – with support for temporal segmentation, instrument annotation, and workflow recognition. The solution can be seamlessly integrated into existing development environments and data pipelines via a documented API.
At the same time, medical professionals benefit from an user interface that visualizes surgical workflows in an understandable way and can be used for quality control, training or surgical documentation.
Whether in the clinic, lab, or industry, our browser-based solution brings structure to surgical video data and opens up new opportunities for analysis, automation, and innovation.

ImViA Core Features
Annotation App
Powerful in-browser annotation – designed for surgical data and real-world collaboration.
- Supports multiple data types: 2D images, 3D volumes, surgical videos, endoscopy, MRI, CT, and more – all in one platform
- Efficient annotation workflows for individuals and teams
- Built-in quality assurance: review processes and documentation features
- Video Object Segmentation (VOS) from selected key frames
- Designed for scalable collaboration across disciplines
ImViA – VOS (Video Object Segmentation) from Key Frames
With ImViA’s VOS feature, object masks are created from a few annotated key frames and automatically propagated across entire video segments:
- Segment once, apply across the sequence
- Saving time while ensuring consistency in surgical video annotation
- Ideal for instrument tracking, workflow recognition, and AI training data generation
AI Model Zoo
- Integrate and manage AI models – whether from Chimaera, your own development, or the open-source ecosystem
- Simplify AI development, training, and deployment through a unified web interface
- Collaborate on model development within interdisciplinary teams
- Built on MONAI Application Packages (MAP) and compatible with NVIDIA Holoscan for real-world medical AI workflows
- Deploy models on desktop GPUs, NVIDIA Jetson, or Enterprise Edge AI platforms like NVIDIA IGX
- Use the web platform as a central development hub, supporting rapid prototyping and validation
- Enable flexible model integration and automation via Python scripting and APIs
- Scale up with batch processing workflows based on Girder Data Management
