| # Introduction | |
| This dataset is designed to detect and analyze defects in wheels. It includes four main classes to help identify potential issues that could affect performance and safety. | |
| Classes: | |
| - **Cracks-Scratches**: Visible lines or marks on the wheel that indicate damage. | |
| - **Discoloration**: Areas where the wheel surface shows abnormal color changes. | |
| - **Shelling**: Parts of the wheel surface that appear pitted or hollowed out. | |
| - **Wheel**: The entire wheel structure. | |
| # Object Classes | |
| ## Cracks-Scratches | |
| ### Description | |
| Lines or seams that appear on the wheel’s surface, often consistent and sometimes deep or shallow. | |
| ### Instructions | |
| - Annotate visible lines and marks that trace across the wheel’s surface. | |
| - The annotations should capture the full extent of each line. | |
| - Do not include smudges or dirt that do not have defined linear shapes. | |
| ## Discoloration | |
| ### Description | |
| Patches or areas on the wheel where the color differs from the rest of the material, indicating potential corrosion or fading. | |
| ### Instructions | |
| - Focus on areas where the color noticeably changes, usually darker or lighter than the surrounding region. | |
| - Exclude regions where lighting changes cause temporary shadows or highlights. | |
| ## Shelling | |
| ### Description | |
| Areas on the wheel surface that are hollowed or indented, resembling small craters or pits. | |
| ### Instructions | |
| - Outline regions that appear to be missing material, forming depressions on the wheel. | |
| - Avoid marking areas that are merely dirty or have surface residue but are not structurally hollowed. | |
| ## Wheel | |
| ### Description | |
| The entire circular structure, including spokes and hubs, typically made of metal or alloy. | |
| ### Instructions | |
| - Locate and enclose the entire wheel, ensuring that the edges of the wheel are precisely defined. | |
| - Include all visible parts of the wheel, but do not extend the annotation over occluding objects such as nearby parts or machinery. |
