2012 Poster Sessions : Supervised Earth Mover’s Distance Learning and Its Computer Vision Applications

Student Name : Fan Wang

Research Areas: Graphics/HCI
Abstract:
Earth Mover’s Distance (EMD) is an intuitive and natural distance metric for comparing two histograms or probability distributions. We propose to jointly optimize the ground distance matrix and the EMD flow-network based on partial ordering of histogram distances in an optimization framework. Two applications in computer vision are used to demonstrate the effectiveness of the algorithm: firstly, we apply the optimized EMD value to face verification, and achieve state-of-the-art performance on public face data sets; secondly, we use the learned EMD flow-network to analyze the internal structure of a set of faces, and consistent paths that demonstrate intuitive transitions on certain facial attributes are found.
