Optimizing Image Quality
For better recognition results, pay attention to the following:
1. Image Clarity
- Use high-resolution images (recommended 1000x1000 pixels or above)
- Avoid blurry or out-of-focus images
- Ensure text edges are sharp and clear
2. Lighting Conditions
- Ensure adequate and even lighting
- Avoid reflections and shadows
- Avoid overexposure or underexposure
3. Text Alignment
- Keep text as horizontal as possible
- Avoid severe tilting (recommended angle less than 15 degrees)
- Ensure high contrast between text and background
4. Background Processing
- Keep background simple, avoid complex patterns
- Ensure clear color difference between text and background
- Avoid background interference
