image input

[wangm-ting]

It is a 2D point-cloud regression,why the input image is R( w x h x 3)?

A point cloud is represented as a set of 3D points {Pi| i = 1, ..., n}, where each point Pi is a vector of its (x, y, z) coordinate plus extra feature channels such as color, normal etc. The input is 2D image but for each point cloud the (x, y, z) coordinates are required.
