| # UI Elements (Web + Desktop) v0.1 |
|
|
| Screenshots of real web pages, synthetic forms and Linux desktop apps. Each screenshot comes |
| with bounding boxes for its **interactive UI elements** and the **text on each element**. |
|
|
| You can use it for: |
| - training UI element detectors (YOLO, DETR, and similar), |
| - screen parsing and GUI grounding for computer-use agents, |
| - Set-of-Mark style pipelines, |
| - evaluating OCR on UI text. |
|
|
| **Every label was generated automatically. Nobody drew any boxes by hand.** |
| - **Web:** pages were rendered in headless Chromium and boxes were read from the live DOM. |
| Shadow DOM and iframes are included. Elements that are hidden, disabled or covered by |
| something else (modals, sticky headers) are skipped. robots.txt was respected. |
| - **Desktop:** Qt and GTK apps ran on an isolated virtual KWin (Wayland) display, and boxes |
| were read from the AT-SPI accessibility tree. |
| - **Synthetic forms:** random form pages styled with Bootstrap, Bulma, Pico, Water.css, |
| Simple.css and MVP.css. They add more checkbox, select and input examples. |
|
|
| Viewports range from phone (390×844) to 2560×1440, in light and dark color schemes. Page |
| language is English or Turkish. |

| ## Contents |
|
|
| | Split | Screenshots | |
| |---|---| |
| | train | 1,245 | |
| | validation | 83 | |

| |---|---| |
| | web | 651 | |
| | synthetic-form | 643 | |
| | desktop-kde | 34 | |
|
|
| The validation split holds different **websites** and **desktop apps** than train, so scores |
| measure generalization, not memorization. |

| ### Classes (38,602 boxes) |
|
|
| | Class | Boxes | |
| |---|---| |
| | button | 6,104 | |
| | link | 20,895 | |
| | input | 2,458 | |
| | checkbox | 7,583 | |
| | select | 1,562 | |
|
|
| | id | class | covers | |
| |---|---|---| |
| | 0 | `button` | buttons, tabs, menu-bar entries, toolbar buttons, `<summary>`, `role=button/tab/menuitem` | |
| | 1 | `link` | links, and list or tree items in sidebars and file views | |
| | 2 | `input` | text fields, search boxes, textareas, spin boxes, contenteditable | |
| | 3 | `checkbox` | checkboxes, radio buttons, switches | |
| | 4 | `select` | dropdowns and combo boxes | |
|
|
| ## Format |
|
|
| Hugging Face `imagefolder`: `data/{train,validation}/*.jpg` plus a `metadata.jsonl` file. |
|
|
| ```json |
| { |
| "file_name": "0ebed0962cef1da5.jpg", |
| "width": 1366, "height": 768, |
| "source": "web", |
| "url": "https://getbootstrap.com/docs/5.3/examples/checkout/", |
| "color_scheme": "light", |
| "objects": { |
| "bbox": [[172, 358, 293, 38]], |
| "category": [2], |
| "text": ["Name on card"] |
| } |
| } |
| ``` |
|
|
| - `bbox` is `[x, y, width, height]` in pixels (COCO style). |
| - `text` is the element's accessible name or visible text. For inputs it is the value or |
| placeholder, and for selects the selected option. It can be an empty string. |
|
|
| ```python |
| from datasets import load_dataset |
| ds = load_dataset("bugraakdemir/ui-elements") |
| ``` |
|
|
| `yolo/ui_elements_yolo.zip` holds the same data in Ultralytics YOLO format, including |
| `data.yaml`: |
|
|
| ```bash |
| yolo detect train data=data.yaml model=yolo11n.pt imgsz=1280 epochs=100 |
| ``` |
|
|
| Use a large `imgsz` (1280). UI elements are small, and at 640 many of them get lost. |
|
|
| ## Known limitations |
|
|
| - This is a first version and it is small. Web pages dominate, and `link` is by far the most |
| common class. You may want to weight or oversample the rarer classes. |
| - There is no Windows or macOS UI yet. On the desktop side, only KDE/Qt apps and one GTK app |
| (pavucontrol) are included. Desktop windows are maximized and have no title bar. |
| - Labels come from the DOM and the accessibility tree, so they inherit those sources' mistakes: |
| - Custom widgets without proper roles are missed. |
| - Some elements are over-labeled, for example whole sidebar groups marked as links. |
| - There is no separate `icon` class. Clickable icons are labeled `button` or `link`. |
