OCR-Algorithm for Detection of Subtitles in Television and Cinema.
Morten Jønsson, Hans-Heinrich Bothe · 2007
Abstract: The OCR-algorithm (optical character recognition) described in this paper is a module in the assistive device SubPal, which should be able to read subtitles from television and camera aloud. The SubPal system is described in detail in (Nielsen & Bothe, 2007). By sampling the television signal (PAL) a binary image is created. This binary image is analysed using the OCR-algorithm for generating text-strings that can be passed on to a speech synthesis box. The requirements and the implementation of the OCR are discussed and some initial results are presented. The algorithm is developed with the purpose of later being implemented in hardware (FPGA).
