Implementation of No-Reference (NR) Point Cloud Quality Assessment Method [1].

How to use

Dataset download

This repository does not provide a dataset. When you test this sourcecode with the BASICS (Broad Quality Assessment of Static Point Clouds in a Compression Scenario) dataset [2], the point clouds can be downloaded from the URL: https://zenodo.org/records/10533088.

Calculation of 9 types of features

9 types of features must be calculated before training and evaluation as follows:

Run FeatureCalc_BASICStraining.m 
Run FeatureCalc_BASICStest.m

After the calculation, "Feature_BASICStraining.csv" and "Feature_BASICStest.csv" are output in "Feature" folder (These csv files have already been prepared by authors in this repository).

Training and test by support vector regression

After calculating the scores, training a support vector regression model and the evaluation are carried out by the following code.

Run TrainingSVRModel.m
