"""**Instructions for Concrete Crack Detection and Segmentation App:**
**Input:**
- Upload one or more concrete crack images using the "Image Input" section.
- Adjust confidence level and distance sliders if needed.
- Upload reference images. (e.g. whole wall with many cracks)
- Input Remarks (e.g. First floor wall on the left)\n
**Buttons:**
- Click "Segment" to perform crack segmentation.
- Click "Clear" to reset inputs and outputs.\n
**Output:**
- View segmented images in the "Image Output" gallery.
- Check crack detection results in the "Results" table.
- Download the PDF report file with detailed information..
**Additional Information:**
- The app uses a YOLOv8 trained model for crack detection with 86.8\% accuracy.
- Results include orientation category, width of the crack (widest), number of cracks per photo, and damage level.
**Notes:**
- Ensure uploaded images are in the supported formats: PNG, JPG, JPEG, WEBP.
- Remarks and Reference Image must have data.
**Enjoy detecting and segmenting concrete cracks with the app!**
