基于自适应LBP的视频文本检测算法
Video Text Detection Algorithm Based on Adaptive LBP
摘要
Abstract
Due to the problem of high complexity and lack of adaptability, an algorithm based on adaptive LBP for video text detection is put forward. The algorithm uses the divided difference of global and local pixel grey to determine the size of adaptive threshold. However, it, having strong adaptability, can maximize the removal of background. At the same time, to reduce the complexity, approximate round masking which simplifies the algorithm by covering multi-direction judgments is presented. Experimental results show that the proposed algorithm can detect characters accurately even in video with complex background, and it is of strong adaptability and good practicality, also has low complexity.关键词
