Omnidirectional Image Datasets |
|
The datasets provided below are image datasets from SUN360 database and visual quality score obtained by subjective assessment experiment.
The images are 60 randomly selected omnidirectional images in SUN360.
In experiment, in order to match the resolution of our HMD, the original high resolution omnidirectional images were down-sampled using bi-cubic interpolation to 2048 x 1024 pixels.
To generate distorted images, we compressed the 60 omnidirectional images using three widely used codec standards, JPEG, JPEG 2000, and HEVC.
In experiment, we selected four different bit rates, 0.5, 1.0, 1.5 and 2.0 bits per pixel for each compression.
The number of total omnidirectional images obtained is 720 (60 scenes x 4 codec standards x 4 bit rates).

Corresponding Subjective Image Quality Score Datasets |
|
The visual quality score is measured using single stimulus continuous quality evaluation (SSCQE).
The number of subjects participated in subjective VR experiment is 15.
The subjects scored their perceived quality in the continuous scale range of 0-100, divided into five grades: excellent, good, fair, poor, and bad.
