具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明的技术方案，并不用于限定本发明的保护范围。
本发明实施例提供一种人物标注方法，参照图1，在第一实施例中，所述人物标注方法包括：
步骤S100、结合肤色过滤和人脸检测以结合肤色过滤和人脸检测以获取已标注人物图片中已标注人物的人物特征。
在本实施例中，已标注人物图片中标注的人物可以为手动标注，也可以以为终端自动标注，还可以是利用若干次人工标注的结果，对未标注的人脸进行自动标注。其中，人工标注可以是多图同时标注，也可以是通过人工手工修改或移除标注；自动标注也可以是同时对单个人物或是多个人物进行单图或多图标注。本实施例中，采用人脸信息对人物图片的人物特征进行检测和识别，并结合肤色过滤和人脸检测技术。人脸检测是基于V-J人脸检测器的框架实现的。传统的V-J人脸检测器通过扫描大量检测框，提取Haar特征，再进行Adaboost算法快速滤掉非人脸的图片框，而在本实施例中，根据人脸中一定包含大部分肤色区域的先验知识，对每个人脸检测框先进行肤色检测，通过肤色检测结果可以快速有效地协助判断是否为人脸，从而作为前一级滤波，过滤掉大部分区域。具体肤色检测时通过大量训练图片得到每个像素的肤色似然度，计算检测框的平均肤色似然度，当大于整幅图像平均肤色似然度时将被保留的图片送入下级分类器，否则滤 掉。然后遍历检测当前本地路径下的所有图片，保存人脸数据，创建关于每个人脸的一个数据单元。此数据单元含有该人脸的人物信息、序号信息、特征向量信息、来源信息、坐标和姿态信息。创建时相关人物信息为空，后续的标注操作会改变这个信息项，来源信息即该人脸的源图路径为读取值，序号信息为设计值，按序递加，坐标信息为人脸检测的结果值，特征向量和姿态信息则为计算结果值。最终特征向量的维度为200维，其中100维是降维后的LBP特征，LBP(Local Binary Pattern，局部二值模式)100维是降维后的HOG(Histogram of Oriented Gradient，方向梯度直方图)特征。HOG特征首先利用SDM算法通过进行特征点定位，定位出左右眼，左右嘴角和鼻尖共五个特征点，通过左右嘴角的坐标可以计算出嘴巴中心的位置，利用嘴巴中心的位置和左右眼三个点作为对齐的标准，通过仿射变化将此三点映射到100*100大小图像上的固定的位置，进行在该100*100大小的人脸图像生提取LBP特征和HOG特征，然后分别利用预先训练好的PCA和LDA降维矩阵分别对LBP和HOG特征降维值100维，分别进行模归一化，串联成200维的特征向量。通过定位好的五个人脸特征点，以及通用三维人脸模型中的对应点的三维坐标，可以反求出对应的旋转映射矩阵，利用此旋转映射矩阵对一个标准的正面人脸框(边长相等，且无旋转)进行变换，便可以得到与人脸姿态相同的三维人脸框，然后可以通过透视投影得到具有明显三维视觉效果的人脸框。
步骤S200、根据获取的已标注人物的人物特征，利用人物特征相似度识别对应的人物，以对未标注人物图片中对应的人物进行聚类标注。
在本实施中，利用人物特征相似度识别对应的人物，根据识别的对应人物，对未标注人物图片中对应的人物采用聚类标注，其中，聚类标注使用K-均值聚类方式，预设一个k值，对所有人物进行聚类，聚类结果分为k类，取每个类的聚类中心进行显示和提示标注，可以读取预设的人物信息 进行选择标注，终端维护一个保存预设人物的文件，这时载入这个文件，就可以在文件提供的人物中选择一个人物进行标注，也允许输入标注。完成这k个聚类中心的人工标注后，触发自动标注，对每个聚类集合，集合内的所有图片和聚类中心图片进行相似度计算，相似度大于阈值的图片和聚类中心采用同样的标注人物。可以对剩余的未标注的图片再次按K-均值聚类，重复上述标注操作，直到放弃循环或者完成所有人物图片的标注。
本实施例提供的人物标注方法，通过结合肤色过滤和人脸检测以获取已标注人物图片中已标注人物的人物特征；根据获取的已标注人物的人物特征，利用人物特征相似度识别对应的人物，以对未标注人物图片中对应的人物进行聚类标注，准确度和标注效率高。
图2为本发明人物标注方法第二实施例的流程示意图，如图2所示，在第一实施例的基础上，所述步骤S100之前包括：
步骤S100A、通过检索本地文件，获取人物图片；集合所有人物图片，形成人物图片集合。
终端检索本地文件，指定一个含有图片的本地路径，获取图片文件，进行人脸检测，获取人物图片，对所有的人物图片进行集合，形成人物图片集合，将所有的人物图片保存在人物图片集合中。
本实施例提供的人物标注方法，通过人脸检测和图片集合，形成人物图片集合，以利于快速标注，大大提升了标注效率。
图3为图1中所述步骤S100的细化流程示意图，如图3所示，所述步骤S100包括：
步骤S110、结合肤色过滤和人脸检测识别人物图片中手动标注的人物。
终端根据拾取人的触屏动作，将触屏信号转换为标示信号，从而结合肤色过滤和人脸检测识别人物图片中手动标注的人物。
步骤S120、根据识别的手动标注的人物，获取手动标注人物的人物特 征。
终端根据识别的手动标注的人物，通过人脸识别等手段，获取手动标注人物的特征，如眼膜、脸部形态特征。
图4为本发明人物标注方法第三实施例的流程示意图，如图4所示，在第一实施例的基础上，第三实施例提供的人物标注方法，所述步骤S200之后包括：
步骤S300、对聚类标注后仍未标注的人物图片中对应的人物进行迭代标注和/或推荐排序。
结束聚类标注环节后，终端可以开始迭代标注，选取一个或多个同人物的图片，完成该人物的标注后，触发终端的推荐排序，根据当前的标注人物，对未标注的人脸图片进行关于当前人物的综合排序，按相似度从高到低排序显示，从而便于人工的进一步标注，选取靠前的人脸进行标注，节约查找时间。在所述标注操作模块中，输入时有选项推荐，推荐项为当前选择的要标注的人脸与不同人物的相似度排序结果。选项推荐的实施方式是：将当前被选中的人脸图片和所有已标注图片进行比较，按相似度排序比较结果，将比较结果对应的人物作为选项推荐人物。然后触发第一轮迭代，对已标注人物的图片和所有未标注人物图片计算相似度，对相似度高于阈值的未标注人物图片自动进行标注。待上一轮标注完之后，可以继续选择人工标注或者迭代，由于在上一轮中，有可能自动标注了一些图片，因此迭代的输入图片改变了，再次迭代可能会有更多其他图片被标注。而针对那些多次迭代依然不能被自动标注的，可以人工补充标注，然后采用迭代标注和推荐排序重复交叉的方式，直至完成所有人脸图片的人物标注。上述的相似度使用的是余弦相似度，余弦相似度就是两个特征向量夹角θ的余弦值，
Figure PCTCN2015073337-appb-000001
在特征向量模归一化的情况下，两个向量的余弦相 似度和其内积成比例。推荐排序的具体实施方式可描述如下，设所有人脸图片的集合为O，已标注为当前人物的图片集A，未标注图片集为B，标注为其他人物的图片集为C。在B中取一个图片X和A中所有图片计算相似度，取最大值作为图片X对A的相似度PX。之后再将X与C中所有图片计算相似度，如果存在相似度PC大于PX，则认为图片X更接近非A的人物，故将PX减1。再完成B中所有图片后，对PX降序排序，只有那些没有被减1的图片会排在前面。这些就是推荐的结果。
本实施例提供的人物标注方法，对聚类标注后仍未标注的人物图片中对应的人物进行迭代标注和/或推荐排序，从而提高标注的效率。
图5为本发明人物标注方法第四实施例的流程示意图，如图5所示，在第一实施例的基础上，第四实施例提供的人物标注方法，所述步骤S200之后包括：
步骤S400、通过源图显示、嵌入显示和/或缩略图显示的方式，对聚类标注的人物图片进行显示。
终端根据识别的对应的人物，对所有图片集合的人物图片按照识别的人物特征，分类进行储存，例如将同一人物的人物图片放在同一文件夹下进行存储，并统计分类后人物图片的数量，进行分类显示，所述显示的方式可以是按源图显示，也可以是人脸信息嵌入显示，还可以是缩略图显示。其中人脸信息嵌入显示时，利用姿态信息突出标识检测到的人脸，利用了freetype(字体)显示中文的方法把人物姓名也显示在图片上。利用标注的人物对图片进行分组，显示含有对应人物的所有图片的缩略图，其中，分组中可以含单人和多人图片，并将人脸信息嵌入显示，从而突出显示选中的人物，并在缩略图显示中提供取消标注的功能。
本实施例提供的人物标注方法，通过源图显示、嵌入显示和/或缩略图显示的方式，提高了标注效率。
图6为本发明终端第一实施例的流程示意图，如图6所示，在第一实施例中，所述终端包括：
获取模块10，配置为结合肤色过滤和人脸检测以获取已标注人物图片中已标注人物的人物特征；
标注模块20，配置为根据获取的已标注人物的人物特征，利用人物特征相似度识别对应的人物，以对未标注人物图片中对应的人物进行聚类标注。
在本实施例中，已标注人物图片中标注的人物可以为手动标注，也可以以为终端自动标注，还可以是利用若干次人工标注的结果，对未标注的人脸进行自动标注。其中，人工标注可以是多图同时标注，也可以是通过人工手工修改或移除标注；自动标注也可以是同时对单个人物或是多个人物进行单图或多图标注。本实施例中，终端的获取模块10采用人脸信息对人物图片的人物特征进行检测和识别，并结合肤色过滤和人脸检测。人脸检测基于V-J人脸检测器的框架实现的。传统的V-J人脸检测器通过扫描大量检测框，提取Haar特征，再进行Adaboost算法快速滤掉非人脸的图片框，而在本实施例中，获取模块10根据人脸中一定包含大部分肤色区域的先验知识，对每个人脸检测框先进行肤色检测，通过肤色检测结果可以快速有效地协助判断是否为人脸，从而作为前一级滤波，过滤掉大部分区域。具体肤色检测时通过大量训练图片得到每个像素的肤色似然度，计算检测框的平均肤色似然度，当大于整幅图像平均肤色似然度时将被保留的图片送入下级分类器，否则滤掉。然后遍历检测当前本地路径下的所有图片，保存人脸数据，创建关于每个人脸的一个数据单元。此数据单元含有该人脸的人物信息、序号信息、特征向量信息、来源信息、坐标和姿态信息。创建时相关人物信息为空，后续的标注操作会改变这个信息项，来源信息即该人脸的源图路径为读取值，序号信息为设计值，按序递加，坐标信息为 人脸检测的结果值，特征向量和姿态信息则为计算结果值。最终特征向量的维度为200维，其中100维是降维后的LBP特征，LBP(Local BinaryPattern，局部二值模式)100维是降维后的HOG(Histogram of OrientedGradient，方向梯度直方图)特征。HOG特征首先利用SDM算法通过进行特征点定位，定位出左右眼，左右嘴角和鼻尖共五个特征点，通过左右嘴角的坐标可以计算出嘴巴中心的位置，利用嘴巴中心的位置和左右眼三个点作为对齐的标准，通过仿射变化将此三点映射到100*100大小图像上的固定的位置，进行在该100*100大小的人脸图像生提取LBP特征和HOG特征，然后分别利用预先训练好的PCA和LDA降维矩阵分别对LBP和HOG特征降维值100维，分别进行模归一化，串联成200维的特征向量。通过定位好的五个人脸特征点，以及通用三维人脸模型中的对应点的三维坐标，可以反求出对应的旋转映射矩阵，利用此旋转映射矩阵对一个标准的正面人脸框(边长相等，且无旋转)进行变换，便可以得到与人脸姿态相同的三维人脸框，然后可以通过透视投影得到具有明显三维视觉效果的人脸框。
在本实施中，终端的标注模块20利用人物特征相似度识别对应的人物，根据识别的对应人物，对未标注人物图片中对应的人物采用聚类标注，其中，聚类标注使用K-均值聚类方式，预设一个k值，对所有人物进行聚类，聚类结果分为k类，取每个类的聚类中心进行显示和提示标注，可以读取预设的人物信息进行选择标注，终端维护一个保存预设人物的文件，这时载入这个文件，就可以在文件提供的人物中选择一个人物进行标注，也允许输入标注。完成这k个聚类中心的人工标注后，触发自动标注，对每个聚类集合，集合内的所有图片和聚类中心图片进行相似度计算，相似度大于阈值的图片和聚类中心采用同样的标注人物。可以对剩余的未标注的图片再次按K-均值聚类，重复上述标注操作，直到放弃循环或者完成所有人物图片的标注。
本实施例提供的终端，通过结合肤色过滤和人脸检测以获取已标注人物图片中已标注人物的人物特征；根据获取的已标注人物的人物特征，利用人物特征相似度识别对应的人物，以对未标注人物图片中对应的人物进行聚类标注，准确度和标注效率高。

终端的获取单元12根据识别的手动标注的人物，通过人脸识别等手段，获取手动标注人物的特征，如眼膜、脸部形态特征。
图9为本发明终端第三实施例的流程示意图，如图9所示，在第一实施例的基础上，所述终端还包括：
排序模块30，配置为对聚类标注后仍未标注的人物图片中对应的人物进行迭代标注和/或推荐排序。
终端的排序模块30结束聚类标注环节后，终端可以开始迭代标注，选取一个或多个同人物的图片，完成该人物的标注后，触发终端的推荐排序，根据当前的标注人物，对未标注的人脸图片进行关于当前人物的综合排序，按相似度从高到低排序显示，从而便于人工的进一步标注，选取靠前的人脸进行标注，节约查找时间。在所述标注操作模块中，输入时有选项推荐，推荐项为当前选择的要标注的人脸与不同人物的相似度排序结果。选项推荐的实施方式是：将当前被选中的人脸图片和所有已标注图片进行比较，按相似度排序比较结果，将比较结果对应的人物作为选项推荐人物。然后触发第一轮迭代，对已标注人物的图片和所有未标注人物图片计算相似度，对相似度高于阈值的未标注人物图片自动进行标注。待上一轮标注完之后，可以继续选择人工标注或者迭代，由于在上一轮中，有可能自动标注了一些图片，因此迭代的输入图片改变了，再次迭代可能会有更多其他图片被标注。而针对那些多次迭代依然不能被自动标注的，可以人工补充标注，然后采用迭代标注和推荐排序重复交叉的方式，直至完成所有人脸图片的人物标注。上述的相似度使用的是余弦相似度，余弦相似度就是两个特征向量夹角θ的余弦值，
Figure PCTCN2015073337-appb-000002
在特征向量模归一化的情况下，两个向量的余弦相似度和其内积成比例。推荐排序的具体实施方式可描述如下，设所有人脸图片的集合为O，已标注为当前人物的图片集A，未标注图片集为B，标注为其他人物的图片集为C。在B中取一个图片X和A中所有图片计算相似度，取最大值作为图片X对A的相似度PX。之后再将X与C中所有图片计算相似度，如果存在相似度PC大于PX，则认为图片X更接近非A的人物，故将PX减1。再完成B中所有图片后，对PX降序排序，只有那些没有被减1的图片会排在前面。这些就是推荐的结果。
