Automatically analyze, segment, and catalog video content (audio, visual, text) to enable precision search and retrieval within massive digital libraries.

Video indexing leverages advanced deep learning models (AI) to transform unstructured video data into time-stamped, searchable metadata. The process is multi-faceted: it extracts speech-to-text transcripts, performs Optical Character Recognition (OCR) for on-screen text, and identifies key entities (faces, objects, brands) via computer vision. For high-volume enterprise applications (e.g., media archives or surveillance), this allows for deep, granular search that goes beyond simple titles. Real-time indexing systems often utilize distributed architectures (Apache Kafka, Elasticsearch) to manage data velocity, ensuring immediate indexing of events (like a 'goal' in a live stream) for instant retrieval across content libraries exceeding millions of hours. This core capability drives content monetization, enhances accessibility (closed captioning), and streamlines digital asset management.

## Recent Public Talks and Demos

### [LectureRAG - ai models + knowledge from university lectures](https://prague.aitinkerers.org/talks/rsvp_IJfc86TUlqg)

Faculty of electrical engineering at CVUT has published recordings of (almost) all Lectures during covid. There is so much information in those, yet the information isn't indexed and there is no way to find it (other then going through all the videos). I am working on a project, which allows you to search these video resources, talk to a chatbot which has access to these information. One more (ambitious) goal is to finetune the model based on recordings of professors and maybe have a concept explained to you in their way.
