In this paper a fast motion estimation method for H.264/AVC named Triplet Search Motion Estimation (TS-ME) is proposed. Similar to some of the traditional fast motion estimation methods and their improved proposals which restrict the search points only to some selected candidates to decrease the computation complexity, proposed algorithm separate the motion search process to several steps but w...

Abstract Einstein-Smoluchowski’s theory and Langevin’s are two main theories to describe Brownian motion. The Einstein-Smoluchowski regards motion as random walking of particles, while the Langevin establishes a differential equation describing particles. Both involve numbers, i.e., only statistical results can be discussed. Based on above theories, this paper presents corresponding simulations...

Large-sized free-form surface design presents some challenges in practice. Especially at the conceptual design stage, sculpting physical models is still essential for surface development, because CAD models are less intuitive for designers to design and modify them. These sculpted physical models can be then scanned and converted into CAD models. However, if the physical models are too big, des...

We investigated the role of somatosensory feedback during bimanual coordination by testing a bilaterally deafferented patient, a unilaterally deafferented patient, and three control participants on a repetitive bimanual circle-drawing task. Circles were drawn symmetrically or asymmetrically at varying speeds with full, partial, or no vision of the hands. Strong temporal coupling was observed be...

This paper proposes a real-time, video based motion capture system using only one video camera. Since conventional video based motion capture systems need many cameras and take a long time to deal with many video images, they cannot generate motion data in real time. Therefore they cannot be used as a real-time input device for a standard PC. On the other hand, the prototype system proposed in ...

Integer-pixel motion estimation (IME) runtime in the H.264 encoder takes up over 50% of the total runtime. In which, many IME algorithms have been developed up to now. On the other hand, fractional-pixel motion estimation (FME) part also occupies about 40% of the total motion estimation runtime. After performing the FME process, 1-3 (dB) PSNR improvement can be achieved. The FME part, therefore...

This paper discusses the human postural control as a system engineering approach problem. Two main approaches are considered: neurological and engineering. From the neurological perspective, the problem is described, main sensory systems are identified, sensor fusion is suggested, and control system architecture and details are presented. Experimental results on both human subjects and on a spe...

The experiment was setup to examine the coordination changes in assembling the movement form of 3-ball cascade juggling. Eight adult participants learned to juggle over 4 weeks of practice. Juggling scores were recorded at each session and performance was videotaped at eight selected sessions for purposes of movement analysis. Once the basic spatial and temporal constraints on cascade juggling ...
