Multi-directional Sobel operator kernel on GPUs
Qiong Chang, Xin Li, Yun Li +1
Sobel is one of the most popular edge detection operators used in image processing. To date, most users utilize the two-directional 3x3 Sobel operator as detectors because of its l…
A case study of the profit-maximizing multi-vehicle pickup and delivery selection problem for the road networks with the integratable nodes
Aolong Zha, Qiong Chang, Naoto Imura +1
This paper is a study of an application-based model in profit-maximizing multi-vehicle pickup and delivery selection problem (PPDSP). The graph-theoretic model proposed by existing…
Enhancing Local Geometry Learning for 3D Point Cloud via Decoupling Convolution
Haoyi Xiu, Xin Liu, Weimin Wang +4
Modeling the local surface geometry is challenging in 3D point cloud understanding due to the lack of connectivity information. Most prior works model local geometry using various…
Enhancing Local Feature Learning Using Diffusion for 3D Point Cloud Understanding
Haoyi Xiu, Xin Liu, Weimin Wang +4
Learning point clouds is challenging due to the lack of connectivity information, i.e., edges. Although existing edge-aware methods can improve the performance by modeling edges, h…
