Image representation: classical approaches

• Frequency based: Fourier transform [Yaroslavsky, Eden 96]
• Frequency and space: wavelets [Meyer 93], [Mallat 98]
• Space:
1. Segmentation: variational approach [Mumford, Shah 88], [Morel, Solimini 94]
2. Adjacency graph of regions [Rosenfeld 74]
3. Tree obtained from a segmentation [Salembier, Garrido 2000]
