基于稀疏表达的视频文字检测方法 ：针对传统视频文字检测方法存在效率较低、计算复杂、精确度不高的不足，提出一种视频文字检测方法，通过基于边缘密度和连
通域分析的文字粗检测得到候选文本行，利用稀疏表达分类产生的过完备词典进行文字行验证。实验结果表明，该方法具有较好的检测性
能，可以应用于视频检索系统。-Expression based on sparse video text detection method: video text detection method for the existence of traditional low efficiency, computational complexity, accuracy is not high enough, make a video text detection method based on edge density and connectivity through domain analysis of the text coarse detection get the candidate text lines, expression classification using sparse over-complete dictionary to produce a line of text verification. Experimental results show that the method has good detection performance can be applied to the video retrieval system.
