摘要:

综合考虑信息量度量的速度、性能要求,提出了相适应的显著图、多特征融合模型;基于区域划分融入空间关系,提出了分块信息熵的图像信息量度量方法(SEII);构建了信息量度量的标注数据集,并设计了性能验证方法。实验结果表明该度量方法符合人眼视觉的评价结果。度量方法在实际视频检索系统中进行对比应用测试,测试表明mAP提高4.4%,检索速度提高1.5倍。

关键词: 视频检索, 关键帧选择, 图像信息量, 显著区域, 多特征融合

Abstract:

To meet the speed and performance requirements, Sub-region entropy based image information measurement (SEII)method was proposed, which integrates the salie region detection, region division and features fusion. And, performance evaluation method was designed and many experiments were carried out, proving SEII coordinates with human vision evaluation.Also,SEII is evaluated in a real video retrieval system,which shows increase about 4.4% of mAP with 1.5 times speedup.

Key words: video retrieval, key frame selection, image information, salient region, features fusion
