Video processing method and device and device for video processing

The embodiment of the invention provides a video processing method and device and a device for video processing. The method comprises the following steps: performing target part fusion processing on a first image and a second image through a pattern-based generation model to generate a fused image, the fused image comprising target part features of the first image and target part features of the second image; performing target part detection on each frame of image in the original video, and determining a target frame image containing a to-be-replaced target part; and performing target part replacement processing on a target frame image in the original video by using the fused image to obtain a target video. According to the embodiment of the invention, the cost of recording the template image can be reduced, and the video processing efficiency and quality can be improved. 本发明实施例提供了一种视频处理方法、装置和用于视频处理的装置。其中的方法包括：通过基于样式的生成模型对第一图像和第二图像进行目标部位融合处理，生成融合图像，所述融合图像中包含第一图像的目标部位特征和第二图像的目标部位特征；对原始视频中的每帧图像进行目标部位检测，确定包含待替换的
