VCL@FER image quality assessment database

VCL@FER database consists of 575 images, 23 out of which are originals, with 4 different degradation types per image and 6 degrees of degradation. The degradation types are: JPEG2000, JPEG, Gaussian noise, White noise. Testing was conducted on 118 subjects who had to grade 11307 images in total (around 96 images per subject). Every image was evaluated between 16 and 36 times. Every subject had to grade different types of degradation in one session, e.g. sessions were not divided on degradation types. This will influence on objective measure performances. Mean Opinion Score (MOS) was calculated according to the Rec. ITU-R BT.500-11.

VCL@FER 数据库包含 575 张图像，其中 23 张为原始图像，每张图像具有 4 种不同的退化类型和 6 个退化程度。退化类型包括：JPEG2000、JPEG、高斯噪声和白色噪声。测试在 118 名受试者中进行，他们总共需要对 11307 张图像进行评分（每位受试者平均约 96 张图像）。每张图像均被评估了 16 至 36 次。每位受试者在一次会话中需要对不同类型的退化进行评分，例如，会话并未根据退化类型进行划分。这将影响客观测量性能。平均意见评分（MOS）是根据 Rec. ITU-R BT.500-11 规范计算的。
