Abstract
The present disclosure relates to a point cloud coding device and a method using a mapping function. The point cloud coding device and method compress attribute values of a point cloud by generating a piecewise linear function that is a nonlinear mapping function based on a distribution of the attribute values. The point cloud coding device and method map the attribute values to values within a limited range by utilizing the nonlinear mapping function.
