Mosaic Style Transfer Using Sparse Autocorrelograms
2019
Zenodo
We introduce a novel mosaic synthesis algorithm for musical style transfer using the autocorrelogram as a feature map. We decompose the autocorrelogram feature map sparsely in a decaying sinusoid basis, using that decomposition as an interpolation scheme in feature space. This efficiently provides gradient information in the mosaicing optimization, including of the challenging time-scale parameters which are usually intractable for discretely sampled signals. The required calculations are
