在步骤S120中，确定所述人物图像中的第一头发区域和人脸区域。
具体实现中，响应于获取到人物图像，电子设备可以通过预训练的语义分割模型对人 物图像进行语义分割，确定出人物图像中的第一头发区域和人脸区域。
其中，预训练的语义分割模型用于对输入的图像进行语义分割处理。
具体来说，电子设备在确定人物图像中的第一头发区域和人脸区域的过程中，具体包括：电子设备可以将人物图像输入至预训练的语义分割模型；电子设备获取预训练的语义分割模型输出的语义分割结果，并基于预训练的语义分割模型输出的语义分割结果，确定出人物图像中的第一头发区域和人脸区域。
在步骤S130中，基于所述第一头发区域和所述人脸区域，确定第二头发区域。
具体实现中，响应于电子设备确定出人物图像中的第一头发区域和人脸区域，电子设备可以基于人物图像中的第一头发区域和人脸区域确定第二头发区域。具体来说，电子设备在基于第一头发区域和人脸区域，确定第二头发区域的过程中，具体包括：电子设备可以根据第一头发区域和人脸区域，确定人物图像中的第一刘海区域。电子设备对第一刘海区域进行衰减处理，得到第二刘海区域。

具体实现中，响应于电子设备确定出人物图像中的待染色区域，电子设备可以以与发色特效选择指令对应的方式对待染色区域进行颜色调节处理，得到处理后的人物图像。具体来说，电子设备可以根据该发色特效选择指令，确定目标头发颜色。电子设备基于该目标头发颜色，调整待染色区域中各个像素的颜色水平，以使待染色区域的头发颜色与目标头发颜色相适配，进而得到处理后的人物图像。
上述特效添加方法中，通过响应于发色特效选择指令，进入特效拍摄模式并获取人物图像；确定人物图像中的第一头发区域和人脸区域；基于第一头发区域和人脸区域，确定第二头发区域；基于第二头发区域和人物图像进行引导滤波，确定待染色区域；最后，以预设颜色渲染待染色区域；如此，可以避免待染色区域可能存在的边界线缺失的情况，能够保证待染色区域有着良好的边缘特性，避免待处理图像中的非头发区域受到渲染处理的影响，实现更加真实且准确地对人物图像中的头发区域进行染色。
在一些实施例中，根据第一头发区域和人脸区域，确定人物图像中的第一刘海区域， 包括：分别对第一头发区域和人脸区域进行膨胀处理，得到膨胀后的第一头发区域和膨胀后的人脸区域；确定膨胀后的第一头发区域与膨胀后的人脸区域之间的重叠区域，作为人物图像中的第一刘海区域。
具体实现中，电子设备在根据第一头发区域和人脸区域，确定第一刘海区域的过程中，具体包括：电子设备可以分别对第一头发区域和的人脸区域进行膨胀处理，得到膨胀后的第一头发区域和膨胀后的人脸区域。具体来说，电子设备可以获取被拍摄人物在待处理图像中的当前头发厚度。然后，在基于该当前头发厚度适应性地对第一头发区域和人脸区域进行膨胀处理。
例如，电子设备可以在预先建立的头发厚度与膨胀系数的正相关关系中，确定与该当前头发厚度对应的目标膨胀系数。然后，电子设备再基于该目标膨胀系数，对第一头发区域和人脸区域进行膨胀处理，得到膨胀后的第一头发区域和膨胀后的人脸区域。
电子设备确定膨胀后的第一头发区域和膨胀后的人脸区域之间的重叠区域，并将该重叠区域，作为人物图像中的第一刘海区域。
本申请实施例的技术方案，通过分别对第一头发区域和的人脸区域进行膨胀处理，得到膨胀后的第一头发区域和膨胀后的人脸区域；确定膨胀后的第一头发区域与膨胀后的人脸区域之间的重叠区域，作为人物图像中的第一刘海区域，如此，可以提高确定第一刘海区域过程中的鲁棒性。

具体实现中，电子设备在分别对第一头发区域和人脸区域进行膨胀处理，得到膨胀后的第一头发区域和膨胀后的人脸区域，具体包括：电子设备可以在头发区域的掩码图中，确定能覆盖第一头发区域的最小矩形。电子设备在获取该最小矩形的短边长度，并在预先建立的短边长度与膨胀系数的正相关关系中，确定与该最小矩形的短边长度对应的膨胀系数。电子设备采用膨胀系数，分别对第一头发区域和人脸区域进行膨胀处理，得到膨胀后的第一头发区域和膨胀后的人脸区域。
本申请实施例的技术方案，通过确定覆盖第一头发区域的最小矩形；查询与最小矩形的短边长度对应的膨胀系数；采用膨胀系数，分别对第一头发区域和人脸区域进行膨胀处理，得到膨胀后的第一头发区域和膨胀后的人脸区域；如此，使得在后续基于膨胀后的第一头发区域和膨胀后的人脸区域确定得到的第一刘海区域可以良好地适配被拍摄人物的头发厚度，提高了染发渲染结果的真实程度。
在一些实施例中，对第一刘海区域进行衰减处理，得到第二刘海区域，包括：获取刘海区域的像素均值；查询与像素均值对应的衰减系数，根据衰减系数，降低第一刘海区域中的各个像素值，得到第二刘海区域。
其中，第二刘海区域中的衰减处理后的第一刘海区域的像素值小于掩码图中的第一刘海区域的像素值。
具体实现中，电子设备在对第一刘海区域进行衰减处理，得到第二刘海区域的过程中，具体包括：电子设备可以获取第一刘海区域的像素值，根据该像素值的像素均值，在像素均值与衰减系数的正相关关系中，查询与像素均值对应的衰减系数；根据衰减系数，对第一刘海区域中的各个像素值进行衰减处理，得到第二刘海区域；其中，第二刘海区域中的衰减处理后的第一刘海区域的像素值小于掩码图中的第一刘海区域的像素值。
其中，第一刘海区域的像素值可以是第一刘海区域的像素均值，还可以是第一刘海区域的像素方差值、或者还可以是第一刘海区域的像素中值，本公开不做具体限定。例如，第一刘海区域的像素均值为120时，衰减系数可以为0.5；第一刘海区域的像素均值为150时，衰减系数可以为0.6等。像素均值与衰减系数的正相关关系可由实验结果确定。
本申请实施例的技术方案，通过获取第一刘海区域的像素均值；查询与像素均值对应的衰减系数；根据衰减系数，对第一刘海区域中的各个像素值进行衰减处理，得到第二刘海区域；如此，可以根据第一刘海区域的像素分布情况，适应性地对第一刘海区域中的各个像素值进行衰减处理，使得在添加发色特效后的刘海区域的染色效果不会过于生硬，提高对了刘海区域的发色进行渲染的真实程度。
在一些实施例中，基于第二头发区域和人物图像进行引导滤波，确定待染色区域，包括：确定人物图像中的方差最大颜色通道对应的目标通道图像；对目标通道图像的图像对比度进行调整，得到调整后的图像；采用调整后的图像对第二头发区域进行引导滤波处理，得到待染色区域。
其中，调整后的图像的图像对比度大于目标通道图像的图像对比度。
具体实现中，电子设备在基于第二头发区域和人物图像进行引导滤波，确定待染色区域的过程中，具体包括：电子设备可以在待处理图像对应的RGB三通道中，确定方差最大的颜色通道。电子设备确定人物图像中的方差最大颜色通道对应的目标通道图像。
电子设备对目标通道图像的图像对比度进行调整，得到图像对比度大于目标图像的图像对比度的调整后的图像。具体来说，电子设备剔除目标通道图像中，指定像素值的像素点；然后将剔除像素点后的图像，拉伸至像素值取值区间内，拉伸后剔除像素点后的图像的像素值的最小值为像素值取值区间的最小值，最大值为像素值取值区间的最大值。例如，像素值取值区间可以为0-255，或者还可以是选取的通道的图像的像素值取值区间。所以，在剔除指定像素值的像素点之前，可以绘制目标图像的直方图。电子设备采用调整后的图像作为引导图，并将第二头发区域作为被引导图，从而进行引导滤波处理，得到待染色区域。
本申请实施例的技术方案，通过确定人物图像中的方差最大颜色通道对应的目标通道图像；对目标通道图像的图像对比度进行调整，得到对比度高的调整后的图像，可以尽可能地减少电子设备在采用调整后的图像对第二头发区域进行引导滤波处理的过程中的数 据计算量，提高了头发染色渲染过程中的实时性。

具体实现中，电子设备在以预设颜色渲染待染色区域的过程中，具体包括：电子设备可以获取特效拍摄模式对应的目标渲染发色。
当然，在电子设备进入特效拍摄模式时，电子设备当前所显示的特效拍摄模式界面中还包括发色选择入口。该发色选择入口用于供用户切换不同的发色渲染特效。电子设备可以响应用户实施于发色选择入口的发色选择指令，进而获取发色选择指令对应的目标渲染发色。
电子设备再基于目标渲染发色，对待染色区域进行颜色渲染。具体来说，电子设备可以基于目标渲染发色，对待染色区域进行调色处理，得到调色后区域。其中，该调色后区域中的头发颜色与该目标渲染发色相匹配。
本申请实施例的技术方案，电子设备在以预设颜色渲染待染色区域的过程中，通过获取特效拍摄模式对应的目标渲染发色，和/或，响应实施于发色选择入口的发色选择指令，以获取发色选择指令对应的目标渲染发色，并基于该目标渲染发色，对待染色区域进行颜色渲染，使得经过渲染后的人物图像可以满足用户的发色特效添加需求，进而无需对人物图像重新进行特效添加处理，提高了电子设备对图像的特效添加效率。
图2是根据一示例性实施例示出的另一种特效添加方法的流程图，该特效添加方法可以由电子设备执行，如图2所示，该特效添加方法包括以下步骤。在步骤S202中，响应于发色特效选择指令，进入特效拍摄模式并获取人物图像。在步骤S204中，将所述人物图像输入至语义分割模型；所述语义分割模型用于对输入的图像进行语义分割处理。在步骤S206中，基于所述语义分割模型输出的语义分割结果，确定所述人物图像中的第一头发区域和人脸区域。在步骤S208中，分别对所述第一头发区域和所述人脸区域进行膨胀处理，得到膨胀后的第一头发区域和膨胀后的人脸区域。在步骤S210中，确定所述膨胀后的第一头发区域与所述膨胀后的人脸区域之间的重叠区域，作为所述人物图像中的第一刘海区域。在步骤S212中，对所述第一刘海区域进行衰减处理，得到第二刘海区域。在步骤S214中，基于所述第二刘海区域和所述第一头发区域，确定所述第二头发区域。在步骤S216中，确定所述人物图像中的方差最大颜色通道对应的目标通道图像。在步骤S218中，对所述目标通道图像的图像对比度进行调整，得到调整后的图像；其中，所述调整后的图像的图像对比度大于所述目标通道图像的图像对比度。在步骤S220中，采用所述调整后的图像对所述第二头发区域进行引导滤波处理，得到待染色区域。在步骤S222中，以预设颜色渲染所述待染色区域。需要说明的是，上述步骤的具体限定可以参见上文对一种特效添加方法的具体限定，在此不再赘述。
