The lightweight MLP-based decoder has become increasingly promising for semantic segmentation. However, the channel-wise MLP cannot expand receptive fields, lacking context modeling capacity, which is critical to In this paper, we propose a parametric-free patch rotate operation reorganize pixels spatially. It first divides feature map into multiple groups and then rotates patches within each g...

Multi-agent Pathfinding is a relevant problem in a wide range of domains, for example in robotics and video games research. Formally, the problem considers a graph consisting of vertices and edges, and a set of agents occupying vertices. An agent can only move to an unoccupied, neighbouring vertex, and the problem of finding the minimal sequence of moves to transfer each agent from its start lo...

A welding seam tracking visual sensor based on laser scanning is designed to solve the problems, such as indistinct image, difficulty in processing image etc., caused by serious arc light interference during welding. This visual sensor is mainly composed of a scanning motor, a linear-array CCD, a scanning rotating mirror and a semiconductor laser. Because the sensor measurement precision relies...

RADIO pulsars are thought to born with spin periods of 0.02−0.5 s 1,2,3 and space velocities of 100-1000 km s −14,5 , and they are inferred to have initial dipole magnetic fields of 10 11 − 10 13 G 2. The average space velocity of a normal star in the Milky Way is only 30 km s −1 , which means that pulsars must receive a substantial 'kick' at birth. Here we propose that the birth characteristic...

The 7-axis articulated robot can arbitrarily rotate the position of elbow by changing angle 7th axis. When a makes detour, it is necessary to properly control both and orientation tool E-axis angle. In this study, we propose deep reinforcement learning method for automatically generating detour paths including

Shape-from-Shading (SfS) is a fundamental problem in Computer Vision. Its goal is to solve the image irradiance equation. One prominent solution is the Fast Marching Method of Kimmel & Sethian. When the light source is oblique, Kimmel & Sethian proposed to rotate the image to the light source coordinate system and then solve an ‘almost’ Eikonal equation. This paper presents a new iterative vari...
