【発明の名称】マッチング追跡アルゴリズムに基づくビデオ符号化方法
Document Type and Number:
Japanese Patent JP2003518883
Kind Code:
A
Abstract:
The invention relates to the field of video encoders and, more particularly, to an encoding method based on an adaptation of the matching pursuit method to an error texture coding process inside triangular meshes. Said process is restricted, at each iteration of the method, to a specific triangle selected according to a predefined criterion. An optimal strategy for atom positioning inside this triangle then consists either in arbitrarily selecting the geometrical barycenter of the selected triangle as the center of the atoms, or re-using the error energy information for atom center positioning, the Displaced Frame Difference (DFD) energy barycenter inside the selected triangle having the highest energy being in the second case arbitrarily chosen as the center of the atoms.
