图1为本公开实施例提供的一种美妆特效的生成方法的流程示意图。该方法可以由美妆特效的生成装置执行，其中，该装置可以由软件和/或硬件实现， 可配置于电子设备中，例如，该装置可以配置在手机或平板电脑中。本公开实施例提供的美妆特效的生成方法适用于制作特效的场景，尤其适用于以已有的特效为基础制作新的特效的场景。如图1所示，本实施例提供的美妆特效的生成方法可以包括：
S101、接收针对第一美妆特效的颜色调整操作。
第一美妆特效为已制作完成的美妆特效，其可以为已发布的特效或尚未发布的美妆特效，该第一美妆特效例如可以为视频特效，如应用于视频中的美妆特效。相应的，颜色调整操作可以为调整一美妆特效(即第一美妆特效)的颜色的操作，如在第一美妆特效的特效调整页面中选择一颜色的操作。该颜色调整操作可以由特效使用者或特效创作者执行，例如，用户在使用美妆特效(如第一美妆特效)的过程中，可以通过执行颜色调整操作对该美妆特效进行颜色调整，并采用调整得到的新美妆特效对视频进行处理；或者，用户在完成对一美妆特效(如第一美妆特效)的制作之后，可以通过执行颜色调整操作对该美妆特效的颜色进行调整，得到一个新的美妆特效。
用户(如特效使用者和/或特效创作者等)在欲对第一美妆特效的颜色进行调整时，可以执行针对该第一美妆特效的颜色调整操作，如切换进入第一美妆特效的特效调整页面，并在该特效调整页面中选择其欲采用对第一美妆特效进行颜色调整的颜色。相应的，电子设备可以接收用户所执行的颜色调整操作。
S102、响应于所述颜色调整操作，确定所述颜色调整操作对应的目标颜色，并根据目标颜色对所述第一美妆特效进行颜色调整，以生成第二美妆特效。
目标颜色可以为颜色调整操作所对应的颜色，如用户通过颜色调整操作所选择的颜色。第二美妆特效可以为用户基于第一美妆特效制作得到的新的美妆特效，如通过对第一美妆特效进行颜色调整和/或位置调整所得到的新美妆特效。
电子设备在接收到针对第一美妆特效的颜色调整操作时，可以确定用户所选择的目标颜色，并根据该目标颜色对第一美妆特效进行颜色调整，如可以根据该目标颜色的颜色信息以及第一美妆特效中每一个像素的初始颜色信息确定相应像素需要调整至的目标颜色信息，并基于每个像素的目标颜色信息对该像素进行颜色调整。从而，用户在调整完成后，可以通过执行特效生成操作指示电子设备生成第二美妆特效，以发布该第二美妆特效或者采用该第二美妆特效进行视频处理。
此外，当用户对第一美妆特效进行调整时，电子设备还可以实时展示调整后的第一美妆特效的预览效果，如可以实时采用调整后的第一美妆特效对预设画面或者摄像头实时采集的画面进行处理，并展示处理得到的预览画面，以便 于用户进行查看。
在本实施例中，用户可以对制作完成的美妆特效进行调整，如用户可以在美妆特效发布之前或美妆特效发布之后将美妆特效重新导入特效制作工具中对其进行调整，无需多次重新绘制美妆特效素材并将其导入特效制作工具中查看效果并制作特效，相较于在绘制美妆特效素材并将其导入特效制作工具中查看效果后，若对美妆特效的效果不满意，则需要重新绘制美妆特效素材并将重新绘制的美妆特效导入特效制作工具查看效果的技术方案而言，能够简化美妆特效的制作难度，提高特效的制作效率，并提高用户的体验。
在一个实施方式中，所述根据目标颜色对所述第一美妆特效进行颜色调整，包括：针对所述第一美妆特效中至少部分像素的至少部分颜色分量，根据所述目标颜色确定当前颜色分量对应的当前调整系数；采用所述当前调整系数和所述第一美妆特效的当前透明度系数调整所述当前颜色分量的颜色分量值。从而，在进行颜色调整时能够综合考虑目标颜色以及美妆特效的原始颜色，提高美妆特效的颜色调整效果。
当前颜色分量可以为当前对其进行颜色调整的颜色分量，即当前需要确定其调整系数的当前像素的颜色分量，如当前像素的红色颜色分量、绿色颜色分量或蓝色颜色分量。当前调整系数可以为当前颜色分量的调整系数。当前透明度系数可以为第一美妆特效在当前时刻的透明度系数，其可以为第一美妆特效的初始透明度系数；也可以为用户调整后的透明度系数，即用户可以通过执行透明度系数调整操作调整第一美妆特效的透明度系数。
示例性的，在对第一美妆特效进行颜色调整时，可以针对第一美妆特效中的至少部分像素，首先，根据目标颜色以及该像素在至少部分颜色通道的颜色分量值确定相应颜色分量对应的调整系数；然后，根据该调整系数和第一美妆特效的当前透明度系数确定相应颜色通道需要调整至的目标颜色分量值，并按照该目标颜色分量值调整该像素的颜色。
可以对第一美妆特效中的每一个像素的每一个颜色分量值进行调整，此时，假设该像素在调整之前在多个颜色通道的初始颜色分量值为(r0，g0，b0)，第一美妆特效的当前透明度系数为G0，所确定的该像素的多个颜色分量对应的调整系数为(cr，cg，cb)，则该像素在多个颜色通道需要调整至的目标颜色分量值可以为(r0crG0，g0cgG0，b0cbG0)。
在一个实施方式中，用户还可以调整第一美妆特效的添加位置，相应的，当所述第一美妆特效为人像美妆特效时，所述方法还包括：响应于针对所述第一美妆特效的位置调整操作，调整所述第一美妆特效在相应人像部位的添加位置。
人像美妆特效可以为针对画面中的人物图像添加的美妆特效，如应用于人脸或人体的美妆特效等，以下以第一美妆特效为应用于人脸的美妆特效为例进行说明。相应的，人像部位可以为人脸部位或人体部位。位置调整操作可以为调整第一美妆特效与其对应的人像部位的相对位置的操作，如作用于第一美妆特效的拖动操作或者针对第一美妆特效的位置缩放操作等。
示例性的，用户在欲调整第一美妆特效的添加位置时，可以执行针对第一美妆特效的位置调整操作，如执行针对第一美妆特效的拖动操作或缩放系数调整操作。从而，电子设备在接收到用户的位置调整操作时，可以根据该位置调整操作确定第一美妆特效需要调整至的目标位置，作为第一美妆特效的添加位置，并可以基于在该添加位置处添加第一美妆特效，以便于用户查看调整后第一美妆特效的预览效果。
在上述实施方式中，用户可以通过位置调整操作调整第一美妆特效的添加位置，如当第一美妆特效的添加位置与其对应的人像部位的显示位置存在偏差时，可以将第一美妆特效调整至与其对应的人像部位的显示位置对齐，或者，当第一美妆特效的添加位置与其对应的人像部位的显示位置对齐时，可以将第一美妆特效调整为与其对应的人像部位的显示位置不对齐，无需多次重新绘制美妆特效素材并将其导入特效制作工具中查看效果并制作美妆特效。从而，不仅能够简化美妆特效的制作难度，提高美妆特效的制作效率；还能够满足不同用户的个性化需求，提高用户的体验。
在一个实施方式中，所述调整所述第一美妆特效在相应人像部位的添加位置，包括：调整所述第一美妆特效在相应人像部位中对应的关键点；根据调整后的所述关键点确定所述第一美妆特效的添加位置。
第一美妆特效在相应人像部位中对应的关键点可以为在相应人像部位添加第一美妆特效时对第一美妆特效进行定位的关键点，即可以根据第一美妆特效在相应人像部位中对应的关键点确定第一美妆特效的添加位置。从而，本实施例可以通过调整第一美妆特效在相应人像部位中对应的关键点调整第一美妆特效在该人像部位中的添加位置。
示例性的，可以根据位置调整操作调整第一美妆特效与相应人像部位的相对位置，根据该相对位置确定调整后第一美妆特效在相应人像部位中对应的每个关键点，并根据该关键点的位置确定第一美妆特效的添加位置，如在采用调整后的第一美妆特效对视频进行处理时，可以识别视频中所显示的人物图像中的相应关键点，并在该相应关键点所对应的位置添加第一美妆特效。从而实现对美妆特效的添加位置的调整，满足用户的个性化需求。
本实施例提供内的美妆特效的生成方法，接收针对第一美妆特效的颜色调 整操作；响应于该颜色调整操作，确定该颜色调整操作对应的目标颜色，并根据该目标颜色对第一美妆特效进行颜色调整，以生成第二美妆特效。本实施例通过采用上述技术方案，直接在第一美妆特效的基础上调整得到第二美妆特效，无需重新绘制美妆特效素材，能够简化美妆特效的制作难度，提高美妆特效的制作效率，并提高用户的体验。
图2为本公开实施例提供的另一种美妆特效的生成方法的流程示意图。本实施例中的方案可以与上述实施例中的一个或多个方案组合。所述根据所述目标颜色确定当前颜色分量对应的当前调整系数，包括：根据所述目标颜色确定当前颜色分量对应的第一子调整系数以及所述当前像素对应的第二子调整系数；基于所述第一子调整系数和所述第二子调整系数计算得到所述当前颜色分量对应的当前调整系数。
所述位置调整操作为缩放系数调整操作，所述调整所述第一美妆特效在相应人像部位中对应的关键点，包括：根据所述缩放系数调整操作对应的目标缩放系数对所述第一美妆特效对应的三维模型进行缩放处理，以调整所述第一美妆特效在所述三维模型中对应的关键点，其中，所述三维模型中的关键点与相应人像部位中的关键点对应。
相应的，如图2所示，本实施例提供的美妆特效的生成方法可以包括：
S201、接收针对第一美妆特效的颜色调整操作。
S202、响应于所述颜色调整操作，确定所述颜色调整操作对应的目标颜色，并根据所述目标颜色确定当前颜色分量对应的第一子调整系数以及所述当前像素对应的第二子调整系数。
第一子调整系数可以为当前像素的当前颜色分量所对应的子调整系数，其可以仅与当前颜色分量对应。第二子调整系数可以为当前像素所对应的子调整系数，其可以与当前像素的多个颜色分量(即当前像素的红色颜色分量、绿色颜色分量和蓝色颜色分量)对应，即当前像素的多个颜色分量可以共用一个第二子调整系数。
示例性的，可以根据目标颜色中与当前颜色分量对应的相应颜色分量的颜色分量值确定当前颜色分量对应的第一子调整系数，并根据目标颜色对应的灰度值或者目标颜色的多个颜色分量值的平均值/中值等计算得到当前像素对应的第二子调整系数。
在一个实施方式中，所述根据所述目标颜色确定当前颜色分量对应的第一子调整系数以及所述当前像素对应的第二子调整系数，包括：根据所述目标颜 色的相应颜色分量的颜色分量值确定当前颜色分量对应的第一子调整系数；以及，根据目标灰度图中与所述当前像素对应的目标像素的第一灰度值以及所述目标颜色对应的第二灰度值，确定所述当前像素对应的第二子调整系数，其中，所述目标灰度图中的像素与所述第一美妆特效中的像素对应。
目标灰度图可以为用于对第一美妆特效进行颜色调整的灰度图，其可以由第一美妆特效的创作者或使用者进行设置，目标灰度图中的像素与第一美妆特效中的像素对应，可以与第一美妆特效中的像素一一对应，以实现对第一美妆特效逐像素的进行颜色调整。相应的，目标像素可以为目标灰度图中与第一美妆特效中的当前像素对应的像素。第一灰度值可以为目标像素的灰度值。第二灰度值可以为目标颜色对应的灰度值，即将目标颜色进行灰度化处理得到的灰度值。
示例性的，在确定第一子调整系数时，可以对目标颜色的相应颜色分量的颜色分量值进行归一化处理得到当前颜色分量的第一子调整系数，如假设目标颜色在红色颜色通道、绿色颜色通道和蓝色颜色通道的颜色分量值为(r1，g1，b1)，则当当前颜色分量为红色颜色分量时，当前颜色分量对应的第一子调整系数为r1/255；当当前颜色分量为绿色颜色分量时，当前颜色分量对应的第一子调整系数为g1/255；当当前颜色分量为蓝色颜色分量时，当前颜色分量对应的第一子调整系数为b1/255。
在确定第二子调整系数时，可以分别对第一灰度值和第二灰度值进行归一化处理，并将二者的乘积作为当前像素对应的第二子调整系数，如假设目标灰度图中与当前像素对应的目标像素的第一灰度值为G0，目标颜色对应的第二灰度值为G1，则当前像素对应的第二子调整系数为G0/255)×(G1/255)。
在本实施例中，可以通过灰度图逐像素调整美妆特效的颜色，实现局部弱化、局部增强和/或阴影等特殊效果，从而在提高美妆特效的创作效率的前提下满足用户的不同需求，并提高美妆特效所呈现出的视觉效果，提高用户的体验。
S203、基于所述第一子调整系数和所述第二子调整系数计算得到所述当前颜色分量对应的当前调整系数。
示例性的，在得到当前像素的当前颜色分量对应的第一子调整系数以及当前像素对应的第二子调整系数之后，可以计算该第一子调整系数和该第二子调整系数的乘积，作为当前像素的当前颜色分量对应的当前调整系数。
当第一美妆特效不存在对应的目标灰度图时，可以仅基于第一子调整系数对第一美妆特效进行颜色调整，即可以直接将当前像素的当前颜色分量对应的第一子调整系数作为当前像素的当前颜色分量的当前调整系数。当第一美妆特 效存在对应的目标灰度图时，也可以仅基于目标灰度图确定当前像素对应的第二子调整系数，如可以根据目标灰度图中与当前像素对应的目标像素的灰度值确定当前像素对应的第二子调整系数，本实施例不对此进行限制。
S204、采用所述当前调整系数和所述第一美妆特效的当前透明度系数调整所述当前颜色分量的颜色分量值。
示例性的，假设当前像素在调整之前在红色颜色通道、绿色颜色通道和蓝色颜色通道的初始颜色分量值为(r0，g0，b0)，目标灰度图中与当前像素对应的像素的灰度值为G0，目标颜色在多个颜色通道的颜色分量值为(r1，g1，b1)，目标颜色对应的灰度值为G1，第一美妆特效的当前透明度系数为c0，并假设所确定的当前像素的多个颜色分量对应的调整系数为(cr，cg，cb)，当前像素在多个颜色通道需要调整至的目标颜色分量值为(r2，g2，b2)，则：cr＝(r1/255)×(G0/255)×(G1/255)；cg＝(g1/255)×(G0/255)×(G1/255)；cb＝(b1/255)×(G0/255)×(G1/255)；当前像素在多个颜色通道需要调整至的目标颜色分量值分别为：r2＝r0crG0＝r0×(r1/255)×(G0/255)×(G1/255)×G0；g2＝g0cgG0＝g0×(g1/255)×(G0/255)×(G1/255)×G0；b2＝b0cbG0＝b0×(b1/255)×(G0/255)×(G1/255)×G0。
S205、响应于针对所述第一美妆特效的缩放系数调整操作，根据所述缩放系数调整操作对应的目标缩放系数对所述第一美妆特效对应的三维模型进行缩放处理，以调整所述第一美妆特效在所述三维模型中对应的关键点，其中，所述三维模型中的关键点与相应人像部位中的关键点对应。
第一美妆特效对应的三维模型可以为对第一美妆特效进行贴图渲染时所采用的模型，其可以采用预设关键点识别算法进行关键点识别，并采用所识别得到的关键点作为网格顶点进行网格划分得到。该关键点识别算法可以与对相应人像部位进行关键点识别时所采用的关键点识别算法相同，并可以与第一美妆特效的创作者在绘制第一美妆特效的特效素材时对基准模型图进行关键点识别时所采用的关键点识别算法相同。三维模型中的关键点可以为三维模型的网格顶点。缩放系数调整操作可以为调整第一美妆特效的缩放系数的操作。相应的，目标缩放系数为该缩放系数调整操作所调整至的缩放系数。
在本实施例中，可以通过对第一美妆特效对应的三维模型进行缩放的方式调整第一美妆特效在三维模型中所对应的关键点，进而调整第一美妆特效在相应人像部位中所对应的关键点，即可以通过对三维模型进行缩放的方式调整第一美妆特效在三维模型中所覆盖的网格，进而调整第一美妆特效在相应人像部位中的添加位置。
示例性的，可以以预设点(如三维模型的中心或三维模型边界上的一点等) 为原点，按照该缩放系数调整操作所调整至的目标缩放系数对三维模型进行缩放处理，如针对三维模型中的每一个网格顶点，假设该网格顶点的坐标为(vx，vy)，原点坐标为(vx0，vy0)，目标缩放系数为(sx，sy)，则缩放后该网格顶点的坐标为([(vx-vx0)×sx]+vx0，[(vy-vy0)×sy]+vy0)。
S206、根据调整后的所述对应关系确定所述第一美妆特效的添加位置，以生成第二美妆特效。
上述对颜色调整操作和缩放系数调整操作所进行响应的顺序仅为示例性的说明，其并不对多个步骤的执行顺序进行限制，例如，用户也可以先执行缩放系数调整操作再执行颜色调整操作，或者交叉执行多次颜色调整操作和多次缩放系数调整操作，此时，电子设备可以依据用户所执行的多个触发操作的顺序对多个触发操作进行响应，从而最终得到第二美妆特效。
