AVOCR: Arabic video OCR

摘要

Nowadays the majority of TV channels are performing digitization of their archival materials. The digitization enhances preservation of records and makes the access to documents easier. However, when the quantity of documents become important the digitization is not enough to insure an efficient access. Indeed, we need to extract semantic information to help users to find what we need quickly. The text included in video sequences is an important needful for indexing and searching system. However, this text is difficult to detect and recognize because of the variability of it size, their low resolution characters and the complexity of the backgrounds. To solve these problems, we propose a system performing in two main tasks: first we extract the textual information from the video sequence and second we recognize this text.
