Abstract

After 15 years of intensive research, it seems still far from seeing the light of solving the problem of content-based image retrieval (CBIR). This seminar will first briefly discuss problems with classical content-based image retrieval approaches. Then a survey on relevance feedback approaches will be given. This will lead to more focused presentation on a set of new learning-based relevance feedback algorithms and systems developed in the last 2 years. In addition, we present a new video content representation framework based on spatio-temporal entropy and energy and human perceptions, and its applications in video retrieval and content-aware video streaming. Demos of research prototypes will be given in this presentation.
