Outline of Final Research Achievements |
This study aimed at learning compact and inherent image representation for high-level vision probelms, and developed advanced image recognition and understanding methods. Our main achievements are three-fold: 1) Based on human’s perception principle, we transformed the raw-image domain into differential excitation domain and proposed to use the micro-texton as local descriptors for retaining all information, which would be distinguishable even for the subtle difference in image structures. 2) We proposed a novel middle-level image representation learning framework via exploring the deviation statistics of local descriptor set on the learned GMM model; 3) We stacked several layers of the middle level representation extraction framework, and proposed multiple-layer fisher network architecture for high-level feature learning. We applied our proposed image representation learning strategy for several image recognition applications, and proved much better performances can be achieved.
