A Large-scale Compressed 360-Degree Spherical Image database

CVIQDatabase

Introduction

CVIQ Database includes 524 compressed images generated from 16 original images. Three popular coding technologies are deployed in the database, which are JPEG, H.264/AVC, and H.265/HEVC, respectively.

The images with names from 1*n to 11*n are compressed by JPEG, with names from 12*n to 22*n are compressed by AVC, with names from 23*n to 33*n are compressed by HEVC, and with names 34*n are original images.

The CVIQ.mat file contains the MOS for each image.
