We propose a new optically written watermarking technology that can enhance the invisibility of watermarking patterns that are projected onto objects. The new method uses repetitive block patterns in which the brightness of pixels where “1” is embedded is slightly higher than that of pixels where “0” is embedded. This difference in brightness is too small(More)
The goal of this study is to propose a data driven approach method to characterize muscular activities of complex actions in sports such as golf from a lot of EMG channels. Two problems occur in a many channel measurement. The first problem is that it takes a lot of time to check the many channel data because of combinatorial explosion. The second problem(More)
