International Journal of Computational Engineering Research||Vol, 03||Issue, 5|| Text Extraction in Video 1, Ankur Srivastava , 2, Dhananjay Kumar, 3, Om Prakash Gupta , 4, Amit Maurya, 5, Mr.sanjay kumar Srivastava 1,2,3,4,5, KIT, Kanpur (Affiliated to Gautam Buddh Technical University, Lucknow) ABSTRACT: The detection and extraction of scene and caption text from unconstrained, general purpose video is an important research problem in the context of content-based retrieval and summarization of visual information. The current state of the art for extracting text from video either makes simplistic assumptions as to the nature of the text to be found, or restricts itself to a subclass of the wide variety of text that can occur in broadcast video. Most published methods only work on artificial text (captions) that is composited on the video frame. Also, these methods have been developed for extracting text from images that have been applied to video frames. They do not use the additional temporal information in video to good effect.This thesis presents a reliable system for detecting, localizing, extracting, tracking and binarizing text from unconstrained, general-purpose video. In developing methods for extraction of text from video it was observed that no single algorithm could detect all forms of text. The strategy is to have a multi-pronged approach to the problem, one that involves multiple methods, and algorithms operating in functional parallelism. The system utilizes the temporal information available in video. The system can operate on JPEG images, MPEG-1 bit streams, as well as live video feeds. It is also possible to operate the methods individually and independently. Keywords — Detection, Extraction, Frame, Images and Tracking. I. INTRODUCTION: As computer, compress technology, storage media and high speed communication skill are developed dramatically; digital video has become one of the most important elements in many applications such as education, news and games. Multimedia data are also getting bigger than before. In order to extract and search important information from a huge amount of video data, we need to extract text from video. Text is obviously an important element in video. So extracting text appears as a key clue for understanding contents of video and for instance for classifying automatically some videos. Videotext detection and recognition has been identified as one of the key components for the video retrieval and analysis system. Videotext detection and recognition can be used in many applications, such as semantic video indexing, summarization, video surveillance and security, multilingual video information access, etc. Videotext can be classified into two broad categories: Graphic text and scene text. Graphic text or text overlay is the videotext added mechanically by video editors, examples include the news/sports video caption, movie credits etc. Scene texts are the videotexts embedded in the real-world objects or scenes, examples include street name, car license number, and the number/name on the back of a soccer player. This report is to address the problem of accurately detecting and extracting the graph videotexts for videotext recognition. Although the overlay text is manually added into the video, the experiments showed they are even as hard to extract as many video objects, such as face, people etc. This is due to the following reasons: 1. Many overlay texts present in the cluttered scene background. 2. There is no consistent color distribution for texts in different videos. Consequently, the color-tone based approach widely used in face or people detection application actually cannot be applied in text detection. 3. The size of the text regions may be very small such that when the color segmentation based approach is applied, the small text region may merge into the large non-text regions in its vicinity. Here we used edge detection based method for extracting the text and it is implemented using Mat lab. Here the two critical angles are defines and the text is extracted and recognized using the coincidence of the edges of the image with the threshold defined based on the critical angles. www.<strong>ijcer</strong>online.com ||May ||2013|| Page 48
Text Extraction in Video II. MAIN CONCEPTS: Text extraction in video consists in three steps. The first one is to find text region in original images. Then the text needs to be separated from background. And finally a binary image has to be produced (for example, text is white and background is black) Difficulties of such a project can be classified in following main categories: 1. Background and text may be ambiguous. 2. Text color may change: text can have arbitrary and non-uniform color. 3. Background and text are sometimes reversed. 4. Text may move. 5. Unknown text size, position, orientation, and layout: captions lack the structure usually associated with documents. 6. Unconstrained background: the background can have colors similar to the text color. The background may include streaks that appear very similar to character strokes. 7. Color bleeding: lossy video compression may cause colors to run together. 8. Low contrast: low bit-rate video compression can cause loss of contrast. Figure 1: Flow Chart for Text Extraction.
