图片超分

使用 SeedVR2 对低分辨率、压缩或轻度模糊的图片进行高清修复与细节增强，在尽量保持原始内容和构图的前提下提升清晰度，适合旧素材修复、内容再利用和高分辨率交付。

典型应用场景

• 低清素材修复：改善压缩噪点、轻度模糊和细节缺失
• 内容升级：将历史图片或小尺寸素材增强后用于高清展示
• 工作流预处理：在图片编辑、3D 重建等任务前提升输入素材质量

最佳实践

TIP

• 当前仅支持 seedvr2 模型
• 建议使用主体清晰、无严重遮挡的原图；超分可以增强已有细节，但无法可靠恢复完全缺失的内容
• 输入支持任务返回的 asset_path、Base64 图片数据或可公开访问的 HTTPS URL

基础示例

cURL

curl -X POST 'https://api.v2fun.ai/api/v1/images/processes' \
  -H 'Authorization: Bearer $V2FUN_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
      "model": "seedvr2",
      "input_image": "https://asset.v2fun.ai/upload/img-basic.png"
    }'

JavaScript

const response = await fetch('https://api.v2fun.ai/api/v1/images/processes', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer $V2FUN_API_KEY',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    "model": "seedvr2",
    "input_image": "https://asset.v2fun.ai/upload/img-basic.png"
  }),
});
const data = await response.json();

Python

import requests

resp = requests.post(
    'https://api.v2fun.ai/api/v1/images/processes',
    headers={
        'Authorization': 'Bearer $V2FUN_API_KEY',
        'Content-Type': 'application/json',
    },
    json={
        "model": "seedvr2",
        "input_image": "https://asset.v2fun.ai/upload/img-basic.png"
    },
)
print(resp.json())
