Purpose The aim of this study is to create a robust and simple collision avoidance approach based on quaternion algebra … collaborative robots (cobots). Design/methodology/approach In this study, an approach based on quaternion algebra is developed to …

probability of quaternion component separation in quaternion discrete cosine transform (QDCT) domain and quaternion wavelet … extracted from the luminance (Y) channel in the quaternion wavelet transform domain to characterize the dependency of position … among quaternion wavelet sub-band coefficients. Finally, an ensemble classifier (EC) is exploited to classify the spliced …

. This is achieved based on a quaternion wind model, which by virtue of its division algebra accounts naturally for the … developed augmented quaternion statistics and perform prediction based on the widely linear model. The proposed quaternion …

Several distributions are studied, simultaneously in the real, complex, quaternion and octonion cases. Specifically …
