WebFor instance, in generative modelling and image-to-image translation, reflection padding avoid some artifacts on the boundary, as noted in the CycleGAN paper, for example. An interesting recent paper is Partial Convolution based Padding by Liu et al, where they sidestep this issue by essentially having the convolution completely ignore the ... WebMay 20, 2015 · “Zero padding” means appending a sequential string (a sequence) of zero-valued samples to the beginning or end of a sequence. I believe what you want to do is: ‘Upsample ()” your time-domain sequence to the desired final sample rate that's compatible with your 2.4 GHz carrier sequence. Next, lowpass filter the upsampled sequence. geoffrey suen
