摘要
Video Text Retouch is a technique for retouching textual content found in many online videos such as screencasts, recorded presentations and many online e-learning videos. Viewed through our special, HTML5-based player, users can edit in real-time the textual content of the video frames, such as correcting typos or inserting new words between existing characters. Edits are overlaid and tracked at the desired position for as long as the original video content remains similar. We describe the interaction techniques, image processing algorithms and give implementation details of the system.
