Note: TIME denotes the time caused only by running the adaptive kernel regression method. : is the time to calculate the gradient information. is the time to calculate the covariance smoothing matrix. is the time to calculate steering kernel regression function. is the sum of , , and . indicates that CPU is chosen as the running processor for the covariance matrix calculation due to the limitation of GPU kernel memory for the large window size. |
