Efficient stereo matching on embedded GPUs with zero-means cross correlation

no code implementations1 Dec 2022 Qiong Chang, Aolong Zha, Weimin WANG, Xin Liu, Masaki Onishi, Lei Lei, Meng Joo Er, Tsutomu Maruyama

By combining this technique with the domain transformation (DT) algorithm, our system show real-time processing speed of 32 fps, on a Jetson Tx2 GPU for 1, 280x384 pixel images with a maximum disparity of 128.

Jointly Learning Propagating Features on the Knowledge Graph for Movie Recommendation

1 code implementation Database and Expert Systems Applications 2022 Yun Liu, Jun Miyazaki, Qiong Chang

In the proposed framework, we use an attention-based multi-hop propagation mechanism to take users and movies as center nodes and extend their attributes along with the connections of the knowledge graph by recursively calculating the different contributions of their neighbors.

Enhancing Local Geometry Learning for 3D Point Cloud via Decoupling Convolution

no code implementations4 Jul 2022 Haoyi Xiu, Xin Liu, Weimin WANG, Kyoung-Sook Kim, Takayuki Shinohara, Qiong Chang, Masashi Matsuoka

Modeling the local surface geometry is challenging in 3D point cloud understanding due to the lack of connectivity information.

Enhancing Local Feature Learning for 3D Point Cloud Processing using Unary-Pairwise Attention

no code implementations1 Mar 2022 Haoyi Xiu, Xin Liu, Weimin WANG, Kyoung-Sook Kim, Takayuki Shinohara, Qiong Chang, Masashi Matsuoka

We present a simple but effective attention named the unary-pairwise attention (UPA) for modeling the relationship between 3D point clouds.
