+# AVA Subset with Metrics
+
+This dataset is a processed subset of the **AVA (Aesthetic Visual Analysis) dataset**, derived from **trojblue/AVA-aesthetics-10pct-min50-10bins**. It includes a selection of images alongside computed **visual quality metrics**.
+
+## **Derivation Process**
+1. **Subset Selection**: Images were extracted from `trojblue/AVA-aesthetics-10pct-min50-10bins`, ensuring a minimum of 50 samples per bin.
+2. **Efficient Local Export**: Images were stored locally using a multi-threaded approach to speed up processing.
+3. **Metric Calculation**: Various **computer vision metrics** were computed using `cv2_metrics` from `procslib`, including sharpness, contrast, and other image quality indicators.
+4. **Data Merging**: The computed metrics were merged back into the dataset, providing additional insights beyond aesthetic scores.
+
+## **Usage**
+This dataset is ideal for:
+- Training models that incorporate both **aesthetic scores and image quality metrics**.
+- Analyzing relationships between **image structure and subjective ratings**.
+- Benchmarking computer vision models on real-world **aesthetic quality assessment**.
+
+The dataset is publicly available for research and model development. 🚀
