Decision trees for error concealment in MPEG video

This page provides details of our research of various error concealment strategies for MPEG video. Here is a brief synopsis of the project.

• Candidate Methods (panning)
• Characteristics of Lost MB
• Tree Building
• Tree Growing
• Concealment Motion Vector

1. March 1999 (DCC'99)
   • How well does each candidate method do?
     
   • What does the tree look like?
     
   • Tree Performance (Size vs. MSE)
     
   • Concealment Example
     
2. Sept 1999 (WCNC'99)
   • Decision Tree vs. Concealment Motion Vector
