最佳实践

图像质量

• 分辨率：分辨率越高，照片上色效果越好
• 对比度：原图对比度良好，有助于 AI 识别细节
• 清晰度：清晰锐利的照片比模糊的照片更适合上色
• 照片状况：上色前进行数字修复可以改善效果

提示词技巧

• 提供背景信息：说明时代、地点或主体
• 指定肤色：如果已知，请描述主体的肤色
• 说明服装颜色：如果知道原始颜色，请一并注明
• 描述场景：户外／室内、季节、一天中的时段

历史准确性

• 研究相关时代，以选用真实的色彩搭配
• 考虑时尚和建筑的地域差异
• 军服和装备都有特定且有据可查的颜色
• 复古汽车和其他车辆的颜色通常有详细记录

模式选择

模式	适用场景	速度	质量
max	最终修复、档案工作、礼物	较慢	最高
eco	快速预览、批量测试、草稿	较快	良好

建议：先使用 eco 模式进行初步测试，再使用 max 生成最终结果。

多轮优化

使用 session_id 迭代并优化上色效果：

# Initial colorization
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Colorize this old portrait photograph with natural colors"}],
    "model": "eachsense/beta",
    "stream": true,
    "image_urls": ["https://example.com/portrait.jpg"],
    "session_id": "portrait-restoration"
  }'

# Refine the result
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "The skin tones look a bit too warm. Can you redo the colorization with cooler, more natural skin tones?"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "portrait-restoration"
  }'

# Further adjustment
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "The dress should be blue, not green. Please adjust the clothing color."}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "portrait-restoration"
  }'

错误处理

错误	原因	解决方案
Failed to create prediction: HTTP 422	余额不足	在 eachlabs.ai 充值
Invalid image URL	URL 无法访问	确保图片 URL 可公开访问
超时	图片过大或场景复杂	将客户端超时时间设为至少 10 分钟
上色效果不佳	源图质量较低	使用分辨率更高、更清晰的源图
