This paper presents a novel snake robot, JiAo, equipped with elliptical wheels that enable both wheeled and body-based locomotion. First, the design of each module of the snake robot is described, which consists of the body link and the transmission system of the elliptical wheels. Second, distinct
This paper introduces a wheel-claw quadruped robot named Lywal-X, which is capable of omnidirectional movement as well as grasping actions. Firstly, the mechanical structure of Lywal-X is designed with a three-degree-of-freedom leg transformation mechanism and a two-degree-of-freedom wheel-claw stru
Pose diversity is an inherent representative characteristic of 2D images. Due to the 3D to 2D projection mechanism, there is evident content discrepancy among distinct pose images. This is the main obstacle bothering pose transformation related researches. To deal with this challenge, we propose a f…
The objective of human parsing is to partition a human in an image into constituent parts. This task involves labeling each pixel of the human image according to the classes. Since the human body comprises hierarchically structured parts, each body part of an image can have its sole position distrib…
This paper presents a novel snake robot with the docking function, which can help the snake robots to connect with each other to achieve a stronger one with double length and double degrees of freedom. First, the mechanical design of the snake robot with docking function is introduced, including the…
This paper introduces a leg-wheel transformable quadruped robot named Lywal which can switch to the leg-mode and the wheel-mode for locomotion, and the claw-mode for picking up and transport functions. First, the mechanical structure of Lywal is designed by using an innovative 2-DoF transformable me…
Audio watermarking has been developed to protect the copyright of audio signals. We considered the use of the distribution of the phase spectrum and propose an effective multi-bit audio watermarking method based on phase shifting. The proposed method is implemented on the basis of a frame-wise frame…
The method reported here realizes an inaudible echo-hiding based speech watermarking by using sparse subspace clustering (SSC). Speech signal is first analyzed with SSC to obtain its sparse and low-rank components. Watermarks are embedded as the echoes of the sparse component for robust extraction.…
This paper proposes a watermarking method for speech signals based on Robust Principal Component Analysis (RPCA) and formant manipulations. As the spectrogram of speech has a relatively sparse structure, the core information of speech is extracted into a sparse matrix using RPCA so that formants can…
