Summary/Abstract: This paper presents a methodology for enhancing palimpsest readability using image processing. Applying CLAHE, noise reduction, and adaptive thresholding enables the extraction of hidden text layers. The results show effective separation of scriptio inferior and superior, supporting further analysis through digital reconstruction and OCR.
