英文摘要：

A new development in stereo image coding research is the application of a deformable mesh. Based on the Delaunay triangular mesh stereo image coding algorithm,a feature-node selection method was proposed in this paPer, which made full use of the edge of objects to select feature nodes. At the establishment of the Delaunay triangular grid, the objects could be parted according to their edges,so as to better reflect the complex movement and deformation of the objects. PSNR value and observations show that the proposed method is superior to the traditional ones,reflecting the details of movement and deformation of the objects much better.
