Video OCR for Video Indexing
OCR is a technique that can greatly help to locate the topics of interest in video via the automatic extraction and reading of captions and annotations. Text in video can provide key indexing information. Recognizing such text for search application is critical. Major difficult problem for character recognition for videos is degraded and deformated characters, low resolution characters or very ...
متن کاملEvaluation Framework for Video OCR
In this work, we present a recently developed evaluation framework for video OCR specifically for English Text but could well be generalized for other languages as well. Earlier works include the development of an evaluation strategy for text detection and tracking in video, this work is a natural extension. We sucessfully port and use the ASR metrics used in the speech community here in the vi...
متن کاملEfficient Video Indexing for Fast-motion Video
Due to advances in recent multimedia technologies, various digital video contents become available from different multimedia sources. Efficient management, storage, coding, and indexing of video are required because video contains lots of visual information and requires a large amount of memory. This paper proposes an efficient video indexing method for video with rapid motion or fast illuminat...
متن کاملVideo OCR for Sport Video Annotation and Retrieval
-This paper presents a video OCR system that automatically extracts closed captions from video frames as keywords (or as we called “cues”) for building annotations of sport videos. In this system, text regions that contain closed captions are first identified using support vector machines (SVMs). We then enhance the identified text regions by using two groups of asymmetric filters and recognize...
متن کاملOptimizing a Video Preprocessor for OCR
This paper describes how opt imal video preprocessor performance can be achieved using a software recogni t ion system and a set of control led exper iments. It basical ly involves opt imizing on a constant threshold and then using recognit ion logic designed f r om that threshold to optimize an adaptive threshold function or threshold operator. By using this technique, the video preprocessor c...
