Synthetic Iris Images

This data set was generated using the stable-diffusion-xl-base-1.0 model. The model was fine-tuned with Dreambooth on a private collection of real iris photographs (30 participants, 119 images) without fine-tuning the text encoders. Fine-tuning parameters included the AdamW optimizer, a learning rate of 1e-4, and 10 epochs, with no prior preservation. The prompt used during generation was: "<i>A photo of a [special token] </i><i>iris.</i>"Following synthesis, all generated images underwent a semi-automated re-identification risk assessment using the <i>Cone of Privacy</i> score alongside manual image comparisons to ensure anonymity.This entire dataset <b>consists exclusively of synthetic images</b>. The number in each subdirectory’s name indicates the guidance scale used during image generation.
