RodinHD：可根据肖像生成高保真3D头像模型 头发细节也有了
RodinHD技术革新3D头像生成，依据肖像照片创造高保真3D角色，尤其是在头发细节处理上实现突破。其核心在于独创的三平面拟合与生成框架，包括为每个角色定制高解析三平面和配置共享解码器，以及通过学习基本与上采样模型的级联来生成细节丰富的高分辨率三平面。针对解码器在连续拟合过程中的遗忘问题，RodinHD引入了任务重放的数据调度策略和权重合并正则化项，优化了对新角色细节的捕捉与呈现能力。
此外，通过优化噪声调度和使用预训练的变分自编码器进行多尺度特征表示计算，RodinHD确保了细节完整保留，并在46000个头像的训练下表现卓越，生成的3D角色在细节上超越传统技术，适应各种野外地像输入，全面革新了现有3D化身生成技术。
