Abstract :
Viewing images as distributions of light quanta enables an information theoretic study of image structures on different scales. This article combines Shannon´s entropy and Witkin and Koenderink´s scale-space to establish a precise connection between the heat equation and the thermodynamic entropy in scale-space. Experimentally the entropy function is used to study global textures
