Point clouds (PC) are a popular representation method both for static 3D models and for free-viewpoint videos (FVV). Compression is necessary to store and transmit the PCs, as the file sizes of these PCs are very high. Quality evaluation is crucial for the development of these compression algorithms.
In this project, the goal is to create a PC quality database using several point cloud compression (PCC) methods and to evaluate the performances of the objective quality metrics. For this purpose, subjective quality scores need to be collected. Possible benefits to the MSc student include learning the cutting-edge point cloud compression technologies, understanding data representation format of PCs, and develop a sense for the quality evaluation research.
