Written Exercise 1: Texture Synthesis
Due on Tues, Sep 28 at 11:59PM
In one page or less, please discuss the trade-offs of synethesizing
textures pixel-by-pixel (as in [efros99]) versus patch-by-patch (as in
[efros01]). How are these trade-offs
different when coherence [ashikhmin01] and multi-resolution
strategies [wei00] are
included in the pixel-by-pixel synthesis (as in [hertzmann01]). Please consider
both the theoretical (how the method samples from a statistical
distribution) and practical (running time, storage, quality, etc.)
aspects of the methods in your discussion.
