针对行人图像外观的多样性以及结构、姿态、场景的复杂性,提出一种有效的精细化行人部件分割方法.该方法实现把一幅行人图像分割成不同的语义区域,主要包含三个阶段,前两个阶段单独训练两个Fast R-CNN(Fast Region-based Convolutional Neural Network,快速区域卷积神经网络)模型,分别用来检测整个人体以及各个部件以获得各类别部件的大体位置;第三个阶段使用基于检索过分割图像的方法来对检测到的各个部件进行分割,最后把各部件分割结果还原到原图坐标上以得到最终的分割结果.实验表明所提方法在三个公开的数据库上,与其他算法相比,分割准确率更高,边缘效果更好.

laying
and occasion in human images
a coarse-to-fine method was proposed for effective human parsing.It can decompose a human image into semantic regions which consists of three phases.In the first two phases
two effective models were trained with Fast Region-based Convolutional Network(Fast R-CNN)to respectively detect human body and clothing items.In the third phase
parsing clothing items based on retrieving similar over-segmented images and morphing them into absolute image coordinates.Experiments are conducted on three public databases
and the experimental results show that proposed method has higher accuracy and promising performance.
