摘要
为了辅助失聪者更好地理解视频内容,研究了视频字幕的动态显示技术,即针对视频中字幕,利用AdaBoost人脸检测与唇运动分析、文字与语音匹配及短时平均能量等技术,显示字幕对应的说话人、说话的语速和音量信息,增强失聪者理解视频内容的能力。实验结果验证了系统的有效性。
In order to assist the heating impairment to enjoy videos, the dynamic display technology of video subtitles was researched. For video subtitles, a rich set of technology including AdaBoost face detection and lip motion analysis, script-speech alignment, short-term energy, etc were all used. Which shows subtitles' speaker, speaking rate and volume information. In this way, the ability of the hearing impairment was enhanced and well enjoyed videos .The results showed the effectiveness of this system.
