Semi-Automatic Initialization for Model Based Coding: A Facial Feature Point Based Approach
Zhengrong Yao, Haibo Li · KTH Publication Database DiVA (KTH Royal Institute of Technology) · 2003
In this paper we address the initialization problem for model-based coding system. A semi-automatic scheme based on using feature points is proposed. It has three features: 1) uses personal feature points, 2) user’s assistance is necessary, and 3) it is a global optimal solution. The minimum spanning tree (MST) technique is used to organize feature points into an ordered path and a dynamic programming based matching technique is developed and used to localize the defined feature points. Promising results are obtained and reported.
