Convolution theorems associated with quaternion linear canonical transform and applications
Xiaoxiao Hu, Dong Cheng, Kit Ian Kou
Novel types of convolution operators for quaternion linear canonical transform (QLCT) are proposed. Type one and two are defined in the spatial and QLCT spectral domains, respectiv…
Monogenic Signal Associated with Linear Canonical Transform and Application to Edge Detection Problems
Dong Cheng, Kit Ian Kou
Monogenic signal is regarded as a generalization of analytic signal from the one dimensional space to the high dimensional space. It is defined by an original signal with the combi…
Quaternion Tensor Train Rank Minimization with Sparse Regularization in a Transformed Domain for Quaternion Tensor Completion
Jifei Miao, Kit Ian Kou, Liqiao Yang +1
The tensor train rank (TT-rank) has achieved promising results in tensor completion due to its ability to capture the global low-rankness of higher-order (>3) tensors. On the other…
Signal reconstruction from noisy multichannel samples
Dong Cheng, Xiaoxiao Hu, Kit Ian Kou
We consider the signal reconstruction problem under the case of the signals sampled in the multichannel way and with the presence of noise. Observing that if the samples are inexac…
