We investigated the characteristics of mechanisms mediating motion discrimination of S-cone isolating stimuli and found a double dissociation between the effects of luminance noise, which masks linear but not non-linear motion, and chromatic noise, which masks non-linear but not linear motion. We conclude that S-cones contribute to motion via two different pathways: a non-linear motion mechanis...

According to the difficulty of marker based motion reconstruction of human torso movements a reduced kinematic formulation of the human spine is introduced, which describes the movement of the first thoracic vertebra in relation to the pelvis. The formulation is for implementation in a multibody model of the human body. As a result the formulation offers convenience in marker based motion captu...

there are many occasions where the base of a robotic manipulator is attached to a moving platform, such as on a moving ship, terrain or space shuttle. in this paper a dynamic model of a robotic manipulator mounted on a moving base is derived using both newton-euler and lagrange-euler methods. the presented models are simulated for a mitsubishi pa10-6ce robotic manipulator characteristics mounte...

one of the debates concerning concepts of “medial motion” and “traversal motion” is the question of which of these two concepts of motion corresponds to motion in the corporeal world. in the present article we intend to employ the language of mathematics to present a model for each of these two concepts to study the above mentioned problem. as a result, medial motion represents a covering funct...

straints, motion capture. In this paper, we present a technique for motion: the problem of adapting an animated motion from one character to another. Our focus is on adapting the motion of one articulated figure to another figure with identical structure but different segment lengths, although we use this as a step when considering less similar characters. Our method creates adaptations that pr...

By the grey-based Taguchi methods, this study attempts to analyze the process parameters pertinent to the multiple performance characteristics of linear motion guides and obtain the multiple performance characteristics of the noise level, push force value and horizontal combination precision of the linear motion guide with multiple qualities. Optimal process parameters are determined by using t...

In the paper the dynamic properties of the internal motion of redundant manipulators are considered. The motion is decoupled into the end-effector motion and the internal motion. Next, the dynamic model of a redundant manipulator is derived. A special attention is given to the inertial properties of the system in the space where internal motion is taking place; we define a null space effective ...

Two classes of algorithms for modeling camera motion in video sequences captured by a camera are proposed. The first class can be applied when there is no camera translation and the motion of the camera can be adequately modeled by zoom, pan, and rotation parameters. The second class is more general in that it can be applied when the camera is undergoing a translation motion, as well as a rotat...

In this paper we have used 3D motion capture data with the aim of detecting and classifying specific human actions. In addition to recognition of basic action classes, actor styles and characteristics such as gender, age, and energy level have also been subject to classification. We have applied and compared three main methods: nearest neighbour search, hidden Markov models, and artificial neur...
