Method and apparatus for object-oriented image representation using irregular meshes

摘要

In an object-oriented image representation apparatus using irregular meshes, Sushinodi blocks an entire image according to image data with blocks of a predetermined size, and contains any object contained in the above-mentioned image An object area extracting unit for extracting a blocked object area made up of image blocks having a predetermined size, and a latticed object area made up of square meshes existing in a blocked object area among a predetermined size of rectangular meshes dividing the entire image size And a rule square mesh forming unit for determining the flow control points, which are fixed points, which are vertices located at corners of the latticed object area, vertices not determined as fixed control points in the latticed object area, For the grided object area, until the number of control points reaches a predetermined threshold, the flow control points Individually comprises correspondence calculation of the energy difference values, the minimum of the irregular mesh formation to repeat the formation of an irregular triangular mesh for the support area, and removing the floating control point removal of the flow control point having an energy difference portion. Therefore, since the mesh representation can be made for an arbitrary object other than the entire image, signal processing can be performed more efficiently than when the entire image is represented by a mesh.
