REIHE INFORMATIK 9 / 98 Automatic Text Segmentation and Text Recognition for Video Indexing Rainer
Efficient indexing and retrieval of digital video is an important function of video databases. One powerful index for retrieval is the text appearing in them. It enables contentbased browsing. We present our methods for automatic segmentation of text in digital videos. The output is directly passed to a standard OCR software package in order to translate the segmented text into ASCII. The algor...
متن کاملAutomatic Video Segmentation and Indexing
Indexing is an important aspect of video database management. Video indexing involves the analysis of video sequences, which is a computationally intensive process. However, effective management of digital video requires robust indexing techniques. The main purpose of our proposed video segmentation is twofold. Firstly, we develop an algorithm that identifies camera shot boundary The approach i...
متن کاملREIHE INFORMATIK 6/96 Indexing and Retrieval of Digital Video Sequences based on Automatic Text Recognition
Efficient indexing and retrieval of digital video is an important aspect of video databases. One powerful index for retrieval is the text appearing in them. It enables contentbased browsing. We present our methods for automatic segmentation and recognition of text in digital videos. The algorithms we propose make use of typical characteristics of text in videos in order to enable and enhance se...
متن کاملTEVI: Text Extraction for Video Indexing
Efficient indexing and retrieval of digital video is an important aspect of video databases. One powerful index for retrieval is the text appearing in them. It enables content based browsing. In this paper, we describe a system for detecting and extracting text appearing in video frames A supervised learning method based on color and edge information is used to detect text regions. After an uns...
متن کاملRobust video text segmentation and recognition with multiple hypotheses
A method for segmenting and recognizing text embedded in video and images is proposed in this paper. In the method, multiple segmentation of the same text region is performed, thus producing multiple hypotheses of binary text images. The segmentation algorithm is stated as a statistical labeling and is based on a markov random field (MRF) model of the label map. Background regions in each hypot...
