Читать книгу Graph Spectral Image Processing - Gene Cheung - Страница 41

This chapter introduces the filtering of graph signals performed in the graph frequency domain. This is a key ingredient of graph spectral image processing presented in the following chapters. The design methods of efficient and fast graph filters and filter banks, along with fast GFT (such attempts can be found in Girault et al. (2018); Lu and Ortega (2019)), are still a vibrant area of GSP: the chosen graph filters directly affect the quality of processed images. This chapter only provided a brief overview of graph spectral filtering. Please refer to the references for more details.
