Abstract

Consider a mosaic image, the edges of the tesseræ being unrelated to pictorial content. Depending upon grout color, the picture is seen as uninterrupted “behind bars” or divided into tiles by “cracks” as in an ancient oil painting. The phenomenology is explored.

Highlights

Consider a mosaic image, the edges of the tesseræ being unrelated to pictorial content
The pictures have chromatic variations, whereas the grout is achromatic in both cases. This is one reason why the grout tends to be perceived as alien to the picture. Another reason for this is that the shape of the tile boundaries is not related to the pictorial content
We concentrate on the case of craquelure as it often occurs in paintings. These are cracks that are unrelated to the pictorial content; Figure 1

Summary

Introduction

The edges of the tesseræ being unrelated to pictorial content. It became desirable to vary the grout gray level, which is how we discovered the present effect. The pictures have chromatic variations, whereas the grout is achromatic in both cases. This is one reason why the grout tends to be perceived as alien to the picture.
