摘要

提出了一种消除红外反射图裂纹的方法。红外反射图显示了古代木板画中的底图——艺术家在底层绘制的基本概念。在油漆老化过程中，由于面板和覆盖地面层的力学性能不同，会出现裂缝。裂缝不仅扰乱了一幅画的外观，而且对底画的线条和笔触的分割也是一个问题。一种基于数学形态学的方法，即粘度形态重建，用于消除裂纹，同时尽可能多地保留笔触的细节。一个先验的信息，裂缝通常比笔触薄，并有一个首选的方向被考虑在内。

Painting crack elimination using viscous morphological reconstruction

A method for the elimination of cracks in infrared reflectograms is presented. Infrared reflectograms show the underdrawing - the basic concept of the artist drawn on the ground layer - in ancient wood panel paintings. Caused by the different mechanical behaviour of the panel and the covering ground layer during the aging of the painting, cracks appear. Cracks not only disturb the appearance of a painting, but are also a problem for segmenting the lines and strokes of the underdrawing. A method based on mathematical morphology, namely morphological reconstruction with viscosity, is used to eliminate the cracks while keeping as much detail as possible in the brush strokes. A priori information that the cracks are usually thinner than the brush strokes and have a preferred orientation is taken into account.
