Portilla-Simoncelli Texture Model

The following notebooks introduce the Portilla-Simoncelli texture model, as first described in Portilla and Simoncelli, 2000, and its implementation in plenoptic.

If you are familiar with the model and its matlab implementation, start with Using the Portilla-Simoncelli model in plenoptic and check out Notable differences between Matlab and Plenoptic Implementations to see how to use the model in plenoptic and the differences between the two implementations.

If you are planning on synthesizing Portilla-Simoncelli texture metamers for your own research, please read Portilla-Simoncelli optimization details and Portilla-Simoncelli Model Limitations.

Understanding Metamers

We strongly recommended reading the metamers tutorial before the notebooks found on this page, as they already assume a basic understanding of metamers.
