Invariance against rotation of 3D objects is one of the essential properties for 3D shape analysis. Recently proposed algorithms have achieved rotationally invariant 3D point set analysis by using inherently rotation-invariant 3D shape features, i.e.

3D point set reconstruction is an important and challenging 3D shape analysis task. Current state-of-the-art algorithms for 3D point set reconstruction employ a deep neural network (DNN) having an encoder–decoder architecture. Recently, the decoder

Object detection is one of the core tasks in computer vision. Object detection algorithms often have difficulty detecting objects with diverse scales, especially those with smaller scales. To cope with this issue, Lin et al. proposed feature pyramid

Unsupervised representation learning of unlabeled multimedia data is important yet challenging problem for their indexing, clustering, and retrieval. There have been many attempts to learn representation from a collection of unlabeled 2D images. In c

In this paper, we propose and evaluate a novel object detection architecture called Cascaded Multi-Channel Feature Pyramid Network, or CM-FPN. The proposed network, which is based on Feature Pyramid Network by Lin et al., employs multi-stage cascaded

Given a query that specifies partial 3D shape, a Part-based 3D Model Retrieval (P3DMR) system finds 3D shapes whose part or parts matches the query. An approach to P3DMR is to partition or segment whole models into sub-parts and performs query-part-t

Hand-drawn sketch is a powerful modality to query 3D shape models. However, specifying a detailed 3D shape by a sketch on the first try without reference (i.e., 3D model or real object) is difficult. In this paper, we aim at a sketch-based 3D shape r

Need to organize 3D shape data has prompted studies on comparison and retrieval of 3D shape models. Being able to query 3D shape models by words, in addition to 3D model examples and 2D sketches, would be quite beneficial. This paper proposes a metho
