A self-portrait of young Leonardo
Politecnico di Torino（都灵理工大学）
摘要：
列奥纳多·达·芬奇最著名的画作之一是一幅用红色粉笔画的自画像，他看起来很老。事实上，在他的一本笔记本中有一幅素描，部分被书面笔记覆盖，这可能是艺术家年轻时的自画像。使用图像处理来去除手写文本并改善图像，允许对两幅肖像进行比较。
英文摘要：
One of the most famous drawings by Leonardo da Vinci is a self-portrait in red chalk, where he looks quite old. In fact, there is a sketch in one of his notebooks, partially covered by written notes, that can be a self-portrait of the artist when he was young. The use of image processing, to remove the handwritten text and improve the image, allows a comparison of the two portraits.
