Signal Classification and Synthesis using Scattering Operators
Since my master thesis I am studying some aspects related to terrain modeling. In the last year I began to study some aspects related to signal classification to understand this process and try to use some information in the synthesis of stationary processes.
I am using the scattering operators to decompose the signal and use this representation to signal classification. It is a good representation for stationary signals, such as terrain and texturing. After understanding the classification problem, I intend to use this representation on terrain and texture synthesis.
The stationary operator theory was proposed by Stephane Mallat et. al. More information can be found in the page of the project.
As part of this research I wrote a technical report, advised by Luiz Velho. Besides this, I presented a talk on IMPA's seminar (both materials in Portuguese).
