modify the abstract section "Modify the abstract - two datasets - "Liver diseases, including abscesses, cysts, and tumors, pose a significant global health challenge, requiring accurate and timely diagnosis for effective treatment. Traditional diagnostic methods rely heavily on manual interpretation of medical images, which is time-consuming, subjective, and prone to errors due to low contrast, irregular lesion boundaries, and intra-class variability. To address these challenges, this study introduces YOLOv12, a state-of-the-art deep learning model, for automated liver lesion detection and segmentation. Leveraging the LIVERSCANPLUSPLUS - v17 dataset—a standardized, annotated collection of 822 liver lesion images—we demonstrate the potential of YOLOv12 to revolutionize liver disease diagnosis. YOLOv12 builds on the strengths of its predecessors, incorporating advanced architectural innovations such as Residual Efficient Layer Aggregation Network (R-ELAN), FlashAttention, and 7×7 separable convolutions. These enhancements enable the model to achieve high precision (95.177%) and real-time performance, even in complex scenarios involving small, occluded, or overlapping lesions. The model was trained for 100 epochs, significantly improving training and validation losses, achieving a mean average precision (mAP50) of 0.91912 for bounding boxes and 0.91912 for masks. Comparative analysis with existing methods highlights YOLOv12's superior performance, outperforming traditional neural networks, U-Net variants, and other deep learning frameworks regarding accuracy, recall, and F1 scores.

Dataset 1 Description: The LIVERSCANPLUSPLUS - v17 dataset addresses this need by providing a standardized, annotated, and augmented collection of liver lesion images. This dataset is designed to facilitate research in medical imaging and computer vision. It is publicly available and includes detailed annotations, pre-processing, and augmentation to support the development of accurate and generalizable models. The LIVERSCANPLUSPLUS - v17 dataset consists of 822 images annotated for liver lesion detection. The dataset is divided into three subsets for training, validation, and testing, as shown in Table 5.

Subset	Percentage	Number of Images	Purpose
Training Set	87%	717	Model training and parameter tuning
Validation Set	9%	70	Hyperparameter optimization
Test Set	4%	35	Final model evaluation
The dataset includes three classes of liver lesions, as described in Table 6.

Class Name	Description	Example Use Case
Liver Abscess	A collection of pus within the liver	Diagnosing infectious liver diseases
Liver Cyst	A fluid-filled sac in the liver	Identifying benign liver conditions
Liver Tumor	Abnormal growth of liver tissue	Detecting malignant liver lesions


1.1.1	Pre-processing
To ensure consistency and quality, each image in the dataset underwent the following pre-processing steps:
1.	Auto-orientation: Pixel data was auto-oriented, and EXIF orientation metadata was stripped to standardize image orientation.
2.	Resizing: Images were resized to a fixed resolution of 640x640 pixels using a stretch method, ensuring uniformity across the dataset.
3.	Data Augmentation
To enhance the dataset's diversity and robustness, three augmented versions of each source image were generated using the following techniques:
•	Flip: 50% probability of horizontal or vertical flipping.
•	Rotation: Equal probability of 90-degree rotations (none, clockwise, counter-clockwise, or upside-down).
•	Cropping: Randomly cropped between 0% and 20% of the image.
•	Rotation: Random rotation between -15° and +15°.
•	Shear: Random shear between -15° and +15° horizontally and vertically.
•	Blur: Random Gaussian blur of up to 2.5 pixels.
•	Noise: Salt and pepper noise applied to 0.5% of pixels.
•	These augmentations simulate real-world variations in imaging conditions, improving the generalization capability of models trained on this dataset. Table 7 provides a summary of the augmentation techniques applied.

Dataset 2 Description
Dataset 2 consists of 3,397 images designed for medical imaging applications, particularly in liver tumor detection and segmentation. The dataset is structured to support machine learning workflows, with a standard split into training, validation, and test sets. The images have undergone basic preprocessing to ensure uniformity, making them suitable for deep learning models in computer-aided diagnosis (CAD) systems.
The dataset is divided into 2,378 training images (70%), 679 validation images (20%), and 340 test images (10%). This distribution ensures sufficient data for model training while maintaining reliable validation and test sets for performance evaluation. The split follows best practices in machine learning, allowing researchers to develop and fine-tune models effectively.
All images have been auto-oriented to correct their alignment and resized to 640×640 pixels using a stretch method. While this ensures consistent dimensions, it may introduce distortions if the original images had varying aspect ratios. Notably, no additional augmentations (such as rotations, flips, or contrast adjustments) were applied, meaning users may need to incorporate these techniques during training to enhance model robustness.
The dataset is available on:
•	Roboflow Universe:  https://universe.roboflow.com/segmentasiliver/project-5c-liver-tumor-aikum/dataset/1 
•	Mendeley Data (alternative link) :  https://data.mendeley.com/datasets/bdszxg5kmp/1 
These resources may provide additional images, annotations, or varied preprocessing techniques that complement Dataset 2. Researchers working on liver pathology, radiomics, or AI in healthcare may find these links valuable for comparative studies or expanded training data.
