10.3 Edge Extraction and Exemplar Selection 205
(a) (b)
Figure 10.5 An example of necessary exemplar selection in which curves denote edges and black
blocks denote skipped regions. (a) Textural exemplar selection in which white blocks are necessary
textural exemplars; (b) structural exemplar selection in which white blocks are necessary structural
exemplars, four types of edges are also distinguished in (b). Also see Figure 10.4 for a practical
example.
by inner samples. In addition, propagation of these blocks, from outer to inner, can
reconstruct the related textural regions.
To further improve visual quality of reconstructed images, additional ...
