Utilizing minimal relevance feedback for ad hoc retrieval
Using relevance feedback can significantly improve (ad hoc) retrieval effectiveness. Yet, if little feedback is available, effectively exploiting it is a challenge. To that end,...

Enhanced 2D/3D Approaches Based on Relevance Index for 3D-Shape Retrieval
We present a new approach for 3D model indexing and retrieval using 2D/3D shape descriptors based on silhouettes or depth-buffer images. To take into account the dispersion of inf...
