A Thangka image theme classification dataset with four categories is a highly valuable resource for both academic and practical applications. This dataset consists of a wide variety of Thangka images, carefully categorized into four distinct themes. These categories may include Deity Thangka, Story Thangka, Mandala Thangka, and Knowledge Thangka, each representing different aspects of Tibetan Buddhist art and culture. The dataset serves as a crucial tool for research in art history, cultural studies, and machine learning.
