 **params:**
 - driving_video: driving video, the motion of the driving video is to be migrated.
-- source_image: source_image, the image will be animated according to the motion of the driving video.
+- source_image: source_image, support single people and multipeople in the image, the image will be animated according to the motion of the driving video.
 - relative: indicate whether the relative or absolute coordinates of the key points in the video are used in the program. It is recommended to use relative coordinates. If absolute coordinates are used, the characters will be distorted after animation.
 - adapt_scale: adapt movement scale based on convex hull of keypoints.
+- ratio: The pasted face percentage of generated image, this parameter should be adjusted in the case of multipeople image in which the adjacent faces are close

 **参数说明:**
 - driving_video: 驱动视频，视频中人物的表情动作作为待迁移的对象
-- source_image: 原始图片，视频中人物的表情动作将迁移到该原始图片中的人物上
+- source_image: 原始图片，支持单人图片和多人图片，视频中人物的表情动作将迁移到该原始图片中的人物上
 - relative: 指示程序中使用视频和图片中人物关键点的相对坐标还是绝对坐标，建议使用相对坐标，若使用绝对坐标，会导致迁移后人物扭曲变形
 - adapt_scale: 根据关键点凸包自适应运动尺度
+- ratio: 贴回驱动生成的人脸区域占原图的比例, 用户需要根据生成的效果调整该参数，尤其对于多人脸距离比较近的情况下需要调整改参数
