### Comparison Table: libvips vs. ImageMagick

| **Feature**         | **libvips**                                                        | **ImageMagick**                                                 |
|---------------------|--------------------------------------------------------------------|-----------------------------------------------------------------|
| **Extraction Speed**| Fast, especially for large images, 4-8 times faster                | Stable performance for various tasks; speed reduction possible for large images |
| **Memory Usage**    | Efficient, loads only required pixels into memory                  | Loads the entire image into memory, potentially consuming more memory |
| **Functionality**   | Optimized for image resizing and conversion; somewhat complex setup| Comprehensive image editing capabilities; intuitive to use      |
| **Supported Formats** | Supports various formats like JPG, PNG, TIFF, WEBP               | Supports more image formats, including PSD, GIF, SVG, and others |
| **Use Cases**       | High-resolution images, server-side image processing, thumbnail generation | Comprehensive image editing tasks, ideal for straightforward usage |

### Benchmark Results

- **Speed**: libvips demonstrated 50-60% faster performance than ImageMagick when handling large images.
- **Memory Usage**: libvips is more memory-efficient, avoiding memory shortages for large images, whereas ImageMagick’s memory usage may increase due to loading the entire image.
- **Benchmark Example**: In large image resizing tasks, libvips was reported to be 4-8 times faster than ImageMagick.
- **Peak Memory Usage**: libvips typically shows lower peak memory usage, while ImageMagick’s memory usage may increase due to full image loading.

### Conclusion
libvips offers superior performance in terms of speed and memory efficiency for large image processing. However, ImageMagick remains useful in many projects due to its comprehensive features and ease of use. The final choice depends on the specific requirements and priorities of your project.
