Best Practices

最佳实践

For Products

产品类图片

  • Lighting: Original image should have even lighting for best results
  • Contrast: High contrast between product and background helps accuracy
  • Shadows: Request shadow preservation for natural-looking results
  • Resolution: Higher resolution input yields better edge quality
  • 光照：原图光照均匀可获得最佳效果
  • 对比度：产品和背景对比度高可提升抠图准确率
  • 阴影：可要求保留阴影让效果更自然
  • 分辨率：输入分辨率越高，边缘质量越好

For Portraits

人像类图片

  • Hair: Mention hair type in prompt for better edge detection
  • Clothing: Describe clothing edges if they blend with background
  • Accessories: Note glasses, jewelry, or items that need preservation
  • 头发：在提示词中说明头发类型可提升边缘检测效果
  • 服装：如果服装和背景融色，可描述服装边缘特征
  • 配饰：说明需要保留的眼镜、珠宝等物品

For Complex Subjects

复杂主体图片

  • Transparency: Mention glass, smoke, or translucent elements
  • Fine Details: Specify fur, feathers, or intricate patterns
  • Multiple Subjects: Describe what should be kept vs removed
