SubLog Extractor Description

The SubLog Extractor was developed to be a VirtualDub filter designed to extract hardcoded subtitles from a video stream. Extracting hardcoded subtitles is really a two parts job : - Identifying the changes in the subtitles frames, dump them into bitmaps files, and create a time index for them. - (optionally) Applying OCR to the resulting bitmaps to extract text data SubLog Extractor Filter is taking care of part #1, while an external application such as SubRip can proceed the OCR from the files dumped by SubLog Extractor. More precisely, SubLog Extractor works the following way: a) Pre-processing - Filtering the input (optionnal). b) Temporal Processing - Differential scanning & frame selection. c) Post-processing (VobSub mode only) - Formating the output.
