Abstract

一种抠图实现方法、装置、设备及存储介质，涉及图像处理技术领域，其包括：获取包含第一目标对象的视频数据和不包含第一目标对象的背景图像，背景图像和视频数据具有相同的背景(110)；截取视频数据中当前帧的图像作为原始图像(120)；将原始图像、背景图像和分割图像输入至抠图应用模型，以得到抠图应用模型输出的第一阿尔法通道输出图像，分割图像通过第二阿尔法通道输出图像得到，第二阿尔法通道输出图像由抠图应用模型处理视频数据中前一帧图像时输出(130)；根据第一阿尔法通道输出图像得到包含第一目标对象的抠图结果(140)。采用上述方法可以解决现有技术中由于人工标定而额外增加人工成本且应用限制性高的技术问题。
