文档介绍：基于视频分割与皮肤检测的视频敏感内容检测技术· 吴铮朱淼良龚建军王东辉浙江大学计算机学院310027 E—mail:******@zju. 摘要:作为网络信息净化技术的需要,本文实现一种综合利用基于内容的图像与视频分析技术的视频敏感内容检测技术。首先,进行视频分割和提取关键帧。我们利用HSV空间颜色距离作为帧问相似度度量的一个基准,结合图像帧间色彩变化剧烈程度判断镜头切变点。其次,进行关键帧图像的皮肤内容检测。根据视频中皮肤的运动性,提取MPEG-I/II中的压缩标准中宏块的运动矢量,将没有运动的区域过滤掉;根据皮肤颜色的聚合性,在YCbCr颜色空间建立了皮肤的基于高斯分布的模型,并用贝叶斯方法判断;根据皮肤细腻均匀的纹理特点,过滤高纹理块,并用形态滤波过滤小碎块。实验结果表明上述方法能够比较有效的在视频中检测出人体皮肤。关键词:皮肤检测视频分割关键帧皮肤模型 Detection ofSensitiveVideo Content based on Video Segmentation and Skin Detection Methods WU Zheng ZHU Miao-liang GONG Jian-jun WANG Dong-hui College puter Science,Zhe JiangUniversity,HangZhou,3 0027 E—mail:******@ Abstract:In need ofinformation filteringtechnique onInteract,we present adetection technique ofsensitive video content thispaper,based on video segmentation and skin detection ,we process video segmentation and extract use color distance HSV color space forcalculation ofin—frames similarity and analyze theshotboundary based on extent ofcolorchanges between ,we detect the human skincontent key themotion feature ofskinregions video,we directly use themotion vectors ofmacro—blocks defined MPEG-I/pression standards theimmobile regions;Notice the convergent property ofskincolor,we present theGaussian Model ofSkin Color inYCbCr color space andjudge theskinpixel withBayesian thesmooth texture ofskin,we adopt aHigh Texture Fil
