Aiming at the drawback of not being able to take into account of imaging range and imaging precision simultaneously for an common atomic force microscopy (AFM), a method based on the automatic image stitching is proposed to construct the global visual field of an AFM. In detail, the scanning rule and corresponding image stitching strategy is firstly designed to structure the overall layout for the...
This paper describes visual route following for a cliff-climbing, tethered mobile robot for the purpose of autonomously traversing extreme terrain in the presence of obstacles. When the robot's tether contacts an obstacle, an intermediate anchor is formed. In order to detach from intermediate anchors and avoid entanglement, the robot must backtrack along its outgoing trajectory. We use the Visual...
We address self-perception and object discovery by integrating multimodal tactile, proprioceptive and visual cues. Considering sensory signals as the only way to obtain relevant information about the environment, we enable a humanoid robot to infer potential usable objects relating visual self-detection with tactile cues. Hierarchical Bayesian models are combined with signal processing and protoobject...
Controlling a robotic rehabilitation artefact such as a hand prosthesis is yet a rather open problem. Particularly, the choice of a human-machine interface (HMI) to enable natural control is still debatable. The traditional choice, i.e. surface electromyography (sEMG), suffers from a number of problems (electrode displacement, sweat, fatigue) which cannot be easily solved. One of its main drawbacks...
In this paper an improvement over our previous work is proposed to handle short-medium range surveillance videos. The features of histogram of oriented social force (HOSF) are the primitive building blocks to capture the interactions among people. To reduce the correlation among data, whitening procedure is applied on features. We use Bag-of-Feature (BoF) to pool HOSF in a given frame. Since our goal...
Several studies have showed the positive effect that real-time presentation of centre of pressure (COP) has on stability. Typically the COP position is depicted in real-time on the screen and it is required that the participant uses this additional information to regulate his/her postural sway. In order to perform the motor task, it requires an attentional load that influences the postural performance...
We present a wavelet-based feature extraction approach for evaluating sound quality of time-varying sounds. Triangular wavelets that are two-dimensional nonseparable wavelets are used for extracting features in both local and global region of the sounds. Various kinds of button sounds represented in the time-frequency plane are transformed into a multi-scale pyramid consisting of three isotropic wavelet...
Distance-preserving dimension reduction techniques can fail to separate elements of different classes when the neighborhood structure does not carry sufficient class information. We introduce a new visual technique, K-epsilon diagrams, to analyze dataset topological structure and to assess whether intra-class and inter-class neighborhoods can be distinguished. We propose a force feature space data...
The art of computer-based game production is an aspiring goal and a challenging task. It involves many different activities, expertise and skills into many different areas such as: game theory, programming skills, multimedia, 2D/3D graphics and animation, sound engineering, story writing, project design and management, physics, logic design, interface programming, artificial intelligence (AI) and...
