In this report, we summarize the first NTIRE challenge on light field (LF) image super-resolution (SR), which aims at super-resolving LF images under standard bicubic degradation with a magnification factor of 4. This develops new dataset called NTIRE-2023 for validation and test, provides toolbox BasicLFSR to facilitate model development. Compared single SR, major SR lies in how exploit complementary angular information from plenty views varying disparities. total, 148 participants have...
Two-wheeled mobile robots with deformed wheels face low stability when climbing steps, and their success rate in overcoming steps is affected by the trajectory. To address these challenges, we propose an improved hybrid genetic adaptive particle swarm optimization (HGAPSO) algorithm to optimize wheels’ trajectory for steps. HGAPSO optimizes maximum minimum values of inertial weight learning factors utilizing region-wide search capabilities algorithm, which substantially improves convergence...
