Dynamic obstacle avoidance method for 3D animation group based on multi-agent reinforcement learning

At the forefront of 3D animation, virtual reality and robotics, it is difficult to realistically and efficiently simulate the group behavior of a large number of people and objects. Previously, traditional rule-based or optimization-based methods often encountered critical proble...

Application and research of image watermark based on free visual size optimization JND algorithm

To address the problems of perceptual redundancy estimation in digital image watermarking, which are poor adaptability to fixed-size inputs and insufficient coordination between local and global visual features, a perceptual redundancy estimation based on perceptually sensitive s...

A Six-Degree-of-Freedom Wave Compensation Parallel Robot with Triple-Loop Fractional-Order PI Control Optimized by Tuna Swarm Optimization

For high-precision attitude adjustment tasks of a six-degree-of-freedom (6-DOF) wave-compensation parallel robot in shipborne applications, strong non-stationary wave excitations, abrupt load changes, and broadband disturbances jointly challenge tracking accuracy and smoothness....
