Videosummy

and

Visiocity Summarization Benchmark

Video Summarization Software

Videosummy can condense hours’ worth of video into a couple of minutes, by preserving key events and vignettes from your original video and removing repetitive visual information. Read in details, our VISIOCITY dataset and benchmark algorithms and evaluations for video summarization across different domains such as surveillance, TV shows, sports, education, events (birthdays and weddings), and different facets of summarization therein.

Document Analytics

Optical Character Recognition (OCR) and Scene text Recognition for Indian languages and Indian context

IndicOCR

Optical Character Recognition for Indian Texts

End-to-end framework for Error Detection and Corrections in Indic-OCR. The system inputs a PDF file of a book, and obtains the OCR output using IndSenz OCR and Google OCR, and then corrects the OCRed text, and provides suggestions for words that probably have mistakes during the OCR method, hence any mistakes during the OCR process can be corrected by the user.
