图1是本公开实施例提供的一种人物风格形象图的生成方法的流程图，本实施例可适用于将人物形象转化为设定风格的情况，该方法可以由人物风格形象图的生成装置来执行，该装置可由硬件和/或软件组成，并一般可集成在具有人物风格形象图的生成功能的设备中，该设备可以是服务器、移动终端或服务器集群等电子设备。如图1所示，该方法包括如下步骤：
步骤110，将原始人物形象图输入第一特征编码器，获得第一人物形象特征编码。
原始人物形象图可以是包含人物形象的图像，可以是通过终端设备的摄像头拍摄获得，或者从数据库获得。第一特征编码器可以对输入的人物形象图进行编码，获得第一人物形象特征编码。第一人物形象特征编码可以由多维矩阵表示。
本实施例中，第一特征编码器由设定神经网络构成，并通过人物形象样本图训练获得。
第一特征编码器的训练方式可以为：获取人物形象样本图；将人物形象样本图输入待训练的第一特征编码器，获得第一样本人物形象特征编码；将第一样本人物形象特征编码输入人物形象生成模型中，获得第一重建人物形象图； 基于第一重建人物形象图和人物形象样本图间的损失函数对待训练的第一特征编码器进行训练，得到第一特征编码器。
人物形象生成模型可以是对生成对抗网络进行训练后获得的模型。图2是本实施例中训练人物形象生成模型的示例图。如图2所示，人物形象生成模型的训练方式为：对生成模型和判别模型进行交叉迭代训练，直到判别模型输出的判别结果的精度满足设定条件，则将训练后的生成模型确定为人物形象生成模型。
交叉迭代训练的过程为：将第一随机噪声数据输入生成模型，获得第一人物形象图；将第一人物形象图和第一人物形象样本图输入判别模型，获得第一判别结果；基于第一判别结果调整生成模型中的参数；将第二随机噪声数据输入调整后的生成模型，获得第二人物形象图；将第二人物形象图和第二人物形象样本图输入判别模型，获得第二判别结果，并确定第二人物形象图和第二人物形象样本图间的真实判别结果；根据第二判别结果和真实判别结果间的损失函数调整判别模型中的参数。
第一人物形象样本图和第二人物形象样本图是获取的人物形象样本图中的样本图。
本实施例中，第一特征编码器是基于训练好的人物形象生成模型训练的。示例性的，图3是本实施例中训练第一特征编码器的示例图。如图3所示，首先将人物形象样本图输入待训练的第一特征编码器，以对人物形象样本图进行编码，输出第一样本人物形象特征编码，然后将第一样本人物形象特征编码输入人物形象生成模型中，输出第一重建人物形象图，最后基于第一重建人物形象图和人物形象样本图间的损失函数对待训练的第一特征编码器进行训练，得到第一特征编码器。
步骤120，确定原始人物形象图与模板图间的属性增量。
属性可以包括形象的偏转角度、年龄、头发颜色、性别及是否睁眼等。模板图可以是与人物风格相匹配的图像。例如：假设人物风格为“万圣节”风格，则模板图则为与“万圣节”风格相匹配的图像。
本实施例中，确定原始人物形象图与模板图间的属性增量的方式可以是：将原始人物形象图输入属性识别器中，输出人物属性信息，将模板图输入属性识别器，获得模板属性信息，计算人物属性信息和模板属性信息间的差值，就可以获得属性增量。其中，属性识别器可以是基于设定神经网络构建的。
步骤130，将属性增量和第一人物形象特征编码输入第二特征编码器，获得 第二人物形象特征编码。
第二人物形象特征编码可以理解为增加了属性增量信息的人物形象特征编码。第二特征编码器可以对输入的属性增量和第一人物形象特征编码进行编码，获得第二人物形象特征编码。第二人物形象特征编码可以由多维矩阵表示。
本实施例中，第二特征编码器可以是基于训练好的人物形象生成模型和第一特征编码器训练获得的。其中，人物形象生成模型和第一特征编码器的训练过程参见上述实施例，此处不再赘述。
第二特征编码器的训练方式为：获取人物形象样本图；将人物形象样本图输入第一特征编码器，获得第二样本人物形象特征编码，将第二样本人物形象特征编码输入人物形象生成模型中，获得第二重建人物形象图；将第二样本人物形象特征编码和真实属性增量输入待训练的第二特征编码器，获得第三样本人物形象特征编码；将第三样本人物形象特征编码输入人物形象生成模型中，获得编辑人物形象图；确定第二重建人物形象图和编辑人物形象图间的预测属性增量；基于预测属性增量和真实属性增量间的损失函数对待训练的第二特征编码器进行训练，得到第二特征编码器。
人物形象样本图可以是大量的不同角度或者不同光线下的人物形象图。确定第二重建人物形象图和编辑人物形象图间的预测属性增量的方式可以是：将第二重建人物形象图和编辑人物形象图分别输入属性识别器，获得二者的属性信息，再计算二者属性信息间的差值，从而获得预测属性增量。图4是本实施例中训练第二特征编码器的示例图。如图4所示，首先将人物形象样本图输入第一特征编码器，输出第二样本人物形象特征编码，然后将第二样本人物形象特征编码输入人物形象生成模型中，输出第二重建人物形象图；再然后将第二样本人物形象特征编码和真实属性增量输入待训练的第二特征编码器，输出第三样本人物形象特征编码；将第三样本人物形象特征编码输入人物形象生成模型中，输出编辑人物形象图；最后确定第二重建人物形象图和编辑人物形象图间的预测属性增量，并基于预测属性增量和真实属性增量间的损失函数对待训练的第二特征编码器进行训练，得到第二特征编码器。
步骤140，将第二人物形象特征编码输入风格形象生成模型，获得初始人物风格形象图。
风格形象生成模型可以将人物形象转换为设定风格的人物图像。本实施例中，设定风格可以是“万圣节”风格。示例性的，图5是本实施例中的一种人物风格形象图，如图5所示，对人像形象中的眼睛、嘴巴、皮肤、头发分别进行了“万圣节”风格的处理，使得该人物形象具有“万圣节”风格。
本实施例中，风格形象生成模型可以是基于训练好的人物形象生成模型训练获得的。人物形象生成模型的训练过程可以参见上述实施例，此处不再赘述。
图6是本实施例中训练风格形象生成模型的示例图，如图6所示，风格形象生成模型的训练方式为：对人物形象生成模型和人物形象判别模型进行交叉迭代训练，直到所述人物形象判别模型输出的判别结果的精度满足设定条件，则将训练后的人物形象生成模型确定为风格形象生成模型。
交叉迭代训练的过程为：获取设定风格人物形象样本图；将第一随机噪声数据输入人物形象生成模型，获得第一风格人物形象图；将第一风格人物形象图和设定风格人物形象样本图输入人物形象判别模型，获得第一判别结果；基于第一判别结果调整人物形象生成模型中的参数；将第二随机噪声数据输入调整后的人物形象生成模型，获得第二风格人物形象图；将第二风格人物形象图和设定风格人物形象样本图输入人物形象判别模型，获得第二判别结果，并确定第二风格人物形象图和设定风格人物形象样本图间的真实判别结果；根据第二判别结果和真实判别结果间的损失函数调整人物判别模型中的参数。
设定风格人物形象样本图可以是具有“万圣节”风格的人物形象图，可以通过虚拟人物渲染或者修图获得。
步骤150，将初始人物风格形象图融合至模板图中，获得目标人物风格形象图。
模板图可以是与设定风格相匹配的图像。例如：假设设定风格为“万圣节”风格，则模板图则为与“万圣节”风格相匹配的图像。示例性的，图7a-图7d为设定风格的模板图。图7a-图7d为与“万圣节”风格相匹配的风格图，且人物形象的数量由1变为4。
本实施例中，为了保证人物风格形象图与模板图的尺寸及位置匹配，需要对初始人物风格形象图进行调整。
示例性的，将初始人物风格形象图融合至模板图中，获得目标人物风格形象图的过程可以是：将初始人物风格形象图中的人物风格形象位置进行平移；将平移后的初始人物风格形象图融合至模板图中，获得目标人物风格形象图。
示例性的，可以将人物风格形象平移至初始人物风格形象图中心。
可选的，将初始人物风格形象图中的人物风格形象平移至初始人物风格形象图中心的方式可以是：将人物风格形象的中心关键点与初始人物风格形象图的中心点对齐。
计算人物风格形象的中心关键点的水平坐标与初始人物风格形象图的中心点的水平坐标间距离差，将人物风格形象的中心关键点的水平坐标与初始人物 风格形象图的中心点的水平坐标间距离差确定为水平距离差，计算人物风格形象的中心关键点的竖直坐标与初始人物风格形象图的中心点的竖直坐标间距离差，人物风格形象的中心关键点的竖直坐标与初始人物风格形象图的中心点的竖直坐标间距离差确定为竖直距离差，根据水平距离差沿水平方向平移人物风格形象，根据竖直距离差沿竖直反向平移人物风格形象，直到人物风格形象的中心关键点与初始人物风格形象图的中心点对齐。
可选的，将初始人物风格形象图中的人物风格形象平移至初始人物风格形象图中心的方式可以是：获取初始人物风格形象图的竖直标准线和水平标准线；提取初始人物风格形象图中人物风格形象的中心关键点及嘴角关键点；确定中心关键点的竖直坐标与竖直标准线的距离差，将中心关键点的竖直坐标与竖直标准线的距离差确定为第一距离差；确定嘴角关键点的水平坐标与水平标准线的距离差，将嘴角关键点的水平坐标与水平标准线的距离差确定为第二距离差；根据第一距离差沿竖直方向平移人物风格形象，根据第二距离差沿水平方向平移人物风格形象，以将人物风格形象平移至初始人物风格形象图中心。
竖直标准线和水平标准线可以根据初始人物风格形象图尺寸以及用户的需求设置。示例性的，图8是本实施例中平移人物风格形象的示例图。如图8所示，假设初始人物风格形象图尺寸为512*512，则以初始人物风格形象图尺寸的左上角顶点为原点建立世界坐标系，则竖直标准线设置为x＝256，水平标准线设置为y＝360，平移人物风格形象，使得人物风格形象的中心关键点落在竖直标准线上，使得嘴角关键点落在水平标准线上。
将初始人物风格形象图融合至模板图中，获得目标人物风格形象图的过程可以是：对模板图中的模板人物形象进行识别，获得识别矩形框；根据识别矩形框将初始人物风格形象图裁剪为设定尺寸的图像；将设定尺寸的图像粘贴至识别矩形框内；获取模板图的人物形象掩膜图；基于人物形象掩膜图将粘贴至识别矩形框内的设定尺寸的图像融合至模板图中，获得目标人物风格形象图。
设定尺寸可以由识别矩形框的尺寸来确定，即使得裁剪后的初始人物风格形象图的尺寸与识别矩形框的尺寸相同。人物形象掩膜图可以理解为由模板图中的模板人物形象所围的区域构成的二值图，例如图7a-图7b中白色区域围成的图即为人物形象掩膜图。本实施例中，将设定尺寸的图像粘贴至识别矩形框的方式可以是：将设定尺寸的图像的左上角顶点与识别矩形框的左上角顶点对齐。
本实施例中，基于所述人物形象掩膜图将所述设定尺寸的图像融合至所述模板图可以按照如下公式计算得到：R＝(mask*output)+(1-mask)*template。其中，R为目标人物风格形象图的像素矩阵，mask为人物形象掩膜图的像素矩 阵，output为设定尺寸的图像的像素矩阵，template为模板图的像素矩阵。
本公开实施例的技术方案，将原始人物形象图输入第一特征编码器，获得第一人物形象特征编码；确定原始人物形象图与模板图间的属性增量；将属性增量和第一人物形象特征编码输入第二特征编码器，获得第二人物形象特征编码；将第二人物形象特征编码输入风格形象生成模型，获得初始人物风格形象图；将所述初始人物风格形象图融合至所述模板图中，获得目标人物风格形象图。本公开实施例提供的人物风格形象图的生成方法，可以生成设定风格的人物形象图，从而提高图像的多样性。
