    • Sketch-based 3D Object Retrieval Using Two Views and a Visual Part Alignment 

      Yasseen, Zahraa; Verroust-Blondet, Anne; Nasri, Ahmad (The Eurographics Association, 2015)
      Hand drawn figures are the imprints of shapes in human's mind. How a human expresses a shape is a consequence of how he or she visualizes it. A query-by-sketch 3D object retrieval application is closely tied to this concept ...

    • 3D Object Retrieval with Parametric Templates 

      Getto, Roman; Fellner, Dieter W. (The Eurographics Association, 2015)
      We propose a 3D object retrieval system which uses parametric templates as prior knowledge for the retrieval. A parametric template represents an object-domain and a semantic concept like 'chair' or 'plane' or a more ...

    • Randomized Sub-Volume Partitioning for Part-Based 3D Model Retrieval 

      Furuya, Takahiko; Kurabe, Seiya; Ohbuchi, Ryutarou (The Eurographics Association, 2015)
      Given a query that specifies partial shape, a Part-based 3D Model Retrieval (P3DMR) system would retrieve 3D models whose part(s) matches the query. Computationally, this is quite challenging; the query must be compared ...

    • Indoor Location Retrieval using Shape Matching of KinectFusion Scans to Large-Scale Indoor Point Clouds 

      Al-Nuaimi, Anas; Piccolrovazzi, Martin; Gedikli, Suat; Steinbach, Eckehard; Schroth, Georg (The Eurographics Association, 2015)
      In this paper we show that indoor location retrieval can be posed as a part-in-whole matching problem of Kinect- Fusion (KinFu) query scans in large-scale target indoor point clouds. We tackle the problem with a local shape ...
