背景移除 API 允许您将 AI 驱动的背景移除功能集成到您的应用程序中。通过简单的 REST API 调用，即可通过编程方式移除图像和视频的背景。

首先，请在以下网址注册 API 密钥： 开发者门户

Authorization: <api_key>

API 参数参考

您可以在 API 请求中包含以下参数。所有文件上传均支持大文件，几乎没有大小限制。

图像处理参数

范围类型默认描述
convert_tostring必需的设置为图像背景移除
modelstringu2netAI模型：u2net（通用物体/人类/事物），u2net_human_seg（针对人类优化），u2netp（快速/轻量级）
alpha_mattingbooleanfalse启用 Alpha 通道遮罩，可使头发和细节边缘更加锐利。
alpha_fgint240前景阈值（0-255）。数值越高，前景检测越严格。
alpha_bgint10背景阈值（0-255）。阈值越低，背景检测越严格。
alpha_erodeint10边缘侵蚀大小（1-25）。控制边缘锐度。
alpha_base_sizeint1000用于 Alpha 通道抠图处理的基准尺寸。尺寸越大，质量越好，但速度较慢。
only_maskbooleanfalse返回黑白蒙版而不是透明图像
bg_typestringtransparent背景类型：透明、彩色或图像
bg_color_valuestring#ffffff背景颜色（十六进制格式）（当 bg_type=color 时）

视频处理参数

范围类型默认描述
convert_tostring必需的设置为视频背景移除
modelstringu2netAI模型：u2net（通用）、u2net_human_seg（人类）、u2netp（快速）
video_formatstringmov输出格式：mov（透明背景）、mattekey（mp4 遮罩）、gif（动画）、video_over_image（视频叠加图像）、video_over_video（视频叠加视频）、gif_with_bg（带背景）、mp4_with_color（带颜色）
alpha_mattingbooleanfalse启用 Alpha 通道抠图以获得更锐利的边缘
alpha_fgint240前景阈值（0-255）
alpha_bgint10背景阈值（0-255）
alpha_erodeint10边缘侵蚀尺寸（1-25）
alpha_base_sizeint1000用于 alpha 蒙版处理的底图尺寸
video_bg_color_enabledbooleanfalse启用纯色背景（适用于 mp4_with_color 格式）
video_bg_colorstring#00ff00背景颜色（十六进制格式）
framerateintauto自定义输出帧速率（1-60 FPS）。留空则与输入视频帧速率一致。
frame_limitintnone仅处理前 N 帧。适用于测试或创建视频片段。
