The social gradient in health is familiar to many readers of scientific journals as a diagonal line on a graph showing the almost universal and often linear relation between people’s social and economic circumstances and their health. The pathways to and from poverty and poverty’s impact on health, however, have also vividly been represented in paintings, particularly in 19th century Europe. Th...

Statistical analysis of abstract paintings is becoming an increasingly important tool for understanding the creative process of visual artists. We present a multifractal analysis of 'poured' paintings from the Abstract Expressionism and Les Automatistes movements. The box-counting dimension (D 0) is measured for the analyzed paintings, as is the associated multifractal depth DD¼D 0 À D N , wher...

We present a system for painting how the appearance of an object changes under different lighting and viewing conditions. The user paints what the object should look like under different lighting conditions (dark, partially dark, fully lit, etc.) and (optionally) different viewing angles. The system renders the object under new lighting conditions and a new viewing angle by combining these pain...

This report presents an algorithm which matches photographs of paintings to a small database. The algorithm uses a modified SIFT approach to match keypoints between paintings. The algorithm is somewhat invariant to size and rotation, highly invariant to perspective change and noise, and can tolerate multiple images in the field of view. Significant optimization was performed, leading to a typic...

In this contribution preliminary studies on the application of Optical Coherence Tomography (OCT) to absolute depth calibration of Laser Induced Breakdown Spectroscopy (LIBS) data in application to revealing stratigraphy of easel paintings are presented. The procedure of in-situ monitoring of LIBS by means of OCT is described. Numerical method developed for precise extraction of the depth of th...

Digital image processing and analysis can be an important tool for the restoration of works of art. This paper presents three applications of image processing in this field: a method for digital crack restoration of paintings, a technique for color restoration of old paintings and a method for mosaicing of partial images of works of art painted on curved surfaces. A digital archiving system for...
