Shashidhara B., Manjunatha H. R.

Abstract: Historical documents hold significant insights into our past, making their preservation essential. Unfortunately, many of these documents have deteriorated over time due to factors such as aging, poor storage conditions, and environmental influences. To ensure that the content of these documents remains accessible for research and understanding, effective binarization is crucial. This study thoroughly examines various techniques for binarizing historical document images, focusing on methods designed to enhance the legibility and accessibility of degraded texts. By addressing the unique challenges posed by degradation, the study contributes valuable insights into improving the preservation and interpretation of historical documents.
