In this paper, we present a framework for video retrieval using caption text and keyframe similarity. To extract caption text, we applied methods detecting and extracting image areas contain caption text and we used Tesseract-OCR engine to convert into plain text, then use Hunspell library for spell words. Next, we used Clucene search engine index and query on this text. We applied shape descriptors APR and ECM to descript keyframes of the video shots and use those descriptors as a feature vector of video shots. From the feature vectors were obtained, we used ANN library to index and search. The system which is built on the web-based application using ASP.NET support keyword-based and keyframe-based query. The results obtained from experiments produced very promising.
