A Projection Method on Measures Sets
We consider the problem of projecting a probability measure on a set of Radon measures. The projection is defined as a solution of the following variational problem:
where is a kernel, and denotes the convolution operator. To motivate and illustrate our study, we show that this problem arises naturally in various practical image rendering problems such as stippling (representing an image with dots) or continuous line drawing (representing an image with a continuous line). We provide a necessary and sufficient condition on the sequence that ensures weak convergence of the projections to . We then provide a numerical algorithm to solve a discretized version of the problem and show several illustrations related to computer-assisted synthesis of artistic paintings/drawings.
