Adaptive Channel Encoding Transformer for Point Cloud Analysis. (arXiv:2112.02507v2 [cs.CV] UPDATED)

Transformer plays an increasingly important role in various computer vision
areas and remarkable achievements have also been made in point cloud analysis.
Since they mainly focus on point-wise transformer, an adaptive channel encoding
transformer is proposed in this paper. Specifically, a channel convolution
called Transformer-Conv is designed to encode the channel. It can encode
feature channels by capturing the potential relationship between coordinates
and features. Compared with simply assigning attention weight to each channel,
our method aims to encode the …
