Figure 1From: From 2D Silhouettes to 3D Object Retrieval: Contributions and Benchmarking"Gallery Set Processing." This figure shows the alignment process on one 3D object of the gallery set. First, we compute the smallest enclosing ball of this 3D object, then we combine PCA with the minimal visual-hull criterion in order to align the underlying 3D model. Finally, we extract three silhouettes corresponding to three canonical views.Back to article page
