The translated data: HandRefiner is a solution for correcting AI-generated hand deformities. Current image generation models often encounter issues when producing hand images, such as incorrect finger counts or bizarre hand shapes. To address this problem, HandRefiner proposes a conditional inpainting method that can correct abnormal hand images without altering other parts of the picture. HandRefiner is characterized by its precision and consistency, effectively correcting deformed hands in generated images while maintaining the consistency of the rest of the image. Although primarily designed for hand images, its fundamental principles and techniques are also applicable to other image generation tasks that require meticulous correction.
