Image Processing of Calligraphy

Calligraphy is the art of handwriting. Different languages and writing systems have different features.
Chinese calligraphy is written with black ink on white paper. The artist uses a red seal as a signature at the bottom. Later, collectors add red seals as historical evidence of ownership.
You can recover the image by removing the red seals and you can process the image in various ways.
