An HMM-based Temporal Difference Learning with Model-Updating Capability for Visual Tracking of Human Communicational Behaviors
Found in: Automatic Face and Gesture Recognition, IEEE International Conference on
By Minh Anh T. Ho, Yoji Yamada, Yoji Umetani
Issue Date:May 2002
pp. 0170
In the development of natural interaction for systems, the trend of using vision toward translating human actions into instruction symbols is arising for the recognition of non-verbal communication channels. We propose an Adaptive Vision-based Attentive Tr...
A Safety Preservation Type Vision System Based on Probabilistic Measures
Found in: International Conference on Robot, Vision and Signal Processing
By Takafumi Yamamoto,Yoji Yamada,Masaki Onishi,Yoshihiro Nakabo
Issue Date:November 2011
pp. 114-117
The study concerns a safety vision system for human-robot collaborative work environments. The vision system is characteristic of having a freedom from structuring the environment by setting passive markings, i.e. neither painting on the floor nor hanging ...
Haptic Invitation of Textures: Perceptually Prominent Properties of Materials Determine Human Touch Motions
Found in: IEEE Transactions on Haptics
By Hikaru Nagano,Shogo Okamoto,Yoji Yamada
Issue Date:July 2014
pp. 1-1
In daily life, certain textures and materials invite our touch motions. To seek the nature of such haptic invitation, we conducted a series of experiments consisting of sensory evaluations and ranking tasks for 36 materials to ascertain their perceptual pr...
Relative Contribution Ratios of Skin and Proprioceptive Sensations in Perception of Force Applied to Fingertip
Found in: IEEE Transactions on Haptics
By Kenya Matsui,Shogo Okamoto,Yoji Yamada
Issue Date:January 2014
pp. 78-85
Humans perceive a force applied to their fingertips by integrating skin and proprioceptive sensations. In this study, we investigated the relative contribution ratios of these sensations using two approaches. Decoupled forces were applied to the finger pad...
Data relocation and prefetching for programs with large data sets
Found in: Proceedings of the 27th annual international symposium on Microarchitecture (MICRO 27)
By Grant Haab, John Gyllenhall, Wen-mei Hwu, Yoji Yamada
Issue Date:November 1994
pp. 118-127
Numerical applications frequently contain nested loop structures that process large arrays of data. The execution of these loop structures often produces memory reference patterns that poorly utilize data caches. Limited associativity and cache capacity re...
