IMAGE REPRESENTATION

ABSTRACT
A new content-adaptive mesh-generation method for image repre-
sentation, based on the greedy point-removal scheme of Demaret
and Iske, is proposed. The proposed method is shown to be capable
of producing meshes of higher quality than those generated by the
scheme of Demaret and Iske, while requiring substantially less com-
putation and memory. Furthermore, with the proposed method, one
can easily tradeoff between mesh quality and computational/mem-
ory complexity as needed. Since a mesh-generation scheme pro-
posed by Yang et al. is a key component of the proposed method,
some factors affecting the performance of this scheme are also ex-
plored.
Index Terms-- Image representations, mesh generation, triangle
meshes, greedy point removal, error diffusion.
