Paula Carrillo :: Blog :: Data Mining for Video Transcoding and Encoding

April 01, 2008

Problem Statement: This project aims to exploit structure in video to enable low complexity encoding. The proposed methods use data mining to reduce the complexity. The goal is to develop data mining tools to predict complex coding modes in videos. The tools exploit structural similarity in video. One of the objectives is to develop a minimum set of attributes to make optimal decisions. The methodology developed will be useful in other data mining problems.   

Motivation and Impact: Data mining has been applied in video analysis and understanding but there has been little work in improving encoding performance using data mining. The proposed approach of exploiting structure in video allows more efficient encoders. The proposed solution improves encoder parallelization. The proposed work will enable better utilization of multi-core and upcoming many-core systems. The proposed project will have applications in high-density video processing systems.

Current Status: This work is part of ongoing research in the Multimedia Lab at FAU. Dr. Yang’s group at Tshingua is also working on advanced video encoding algorithms. We expect to explore the complexity vs. quality tradeoffs. Preliminary results confirm the potential of data mining in video coding applications.
