I am intrigued by the analogs between the compositional rules and color theory principles that artists use and the statistical properties of images. For example, the compositional principle that an image be balanced horizontally and vertically is equivalent to stating that the first horizontal and vertical geometric  moments are zero. I start with a given set of desirable statistical properties for an image.  These composition constraints can be written as equations which the pixel values of the image must satisfy.  I use optimization techniques to produce images that simultaneously satisfy several pre-specified compositional constraints.
