Mayachitra's key technologies
VIS™:Visual Indexing and Search
VIS™ has a unique capability to derive, store and access metadata, content descriptors, and scene classification labels for large archives of images and video. VIS™ can help analysts to quickly retrieve image regions or video clips from large archives that are similar in activity, appearance, metadata (or combination of) to the query video clips or image examples.
VIS™ offers
- Automated image and video labeling to generate annotations and context information for further intelligence.
- Video activity search and retrieval.
- Interactive query refinement for video and image content based search.
- Flexible modules for advanced image registration.
- Open architecture and customization.
