## Dataset Summary
This dataset contains microscopic images of white blood cells for the purpose of identifying and classifying Acute Lymphoblastic Leukemia (ALL). It provides a valuable resource for researchers and practitioners in the field of medical imaging and hematology.
| Field Name | Data Type | Description | Example Value | Usage |
|---|---|---|---|---|
| `subject_id` | String | Unique identifier for each patient | "1", "H24" | Patient-level grouping, analysis |
| `image_number` | Integer | Sequential number for images from the same patient | 1, 10, 22 | Image ordering, tracking |
| `cell_count` | Integer | Number of cells in the image | 1, 2, 12 | Feature for analysis/modeling |
| `image` | Image | Microscopic image of blood cells | (Binary image data) | Input for image analysis |
| `label` | String | Simple label (cancer/normal) | "cancer", "healthy" | Target variable for classification |
| `class_label` | String | Alias for `label` | "all", "hem" | Synonym for `label` |
| `fold` | Integer | Cross-validation fold assignment | 0, 1, 2 | Model training/evaluation |
| `original_image_name` | String | Original filename of the image | "UID_1_1_1_all.bmp" | Reference to source data |
| `relative_file_path` | String | Path to image relative to dataset root | "fold_0/all/UID_1_1_1_all.bmp" | Locating image files |
## Supported Tasks and Leaderboards
The dataset is well-suited for various machine learning tasks, including:
* **Image Classification:** Distinguish between ALL and healthy (HEM) cells.
* **Object Detection:** Locate and count individual cells within the images.
* **Segmentation:** Delineate the boundaries of individual cells in the images.
The ISBI 2019 ALL Challenge provided a leaderboard to benchmark performance on the classification task. You can find more information about the challenge and its results here: [https://doi.org/10.7937/tcia.2019.dc64i46r](https://doi.org/10.7937/tcia.2019.dc64i46r)
## Data Splits
The dataset is provided as a single split (`train`) containing all 10,661 images. Researchers are encouraged to create their own validation and test splits, or utilize the pre-defined folds for cross-validation experiments.
