Dataset Description

This dataset was constructed to analyze the influence of image semantic categories (scene categories and object categories) on visual Quality of Experience (QoE). 79 reference images were selected from the LabelMe image annotation dataset, such that they included a balanced number of different scene and object categories. The scene categories include indoor, outdoor natural, and outdoor manmade. The object categories include animate objects (human and animals), and inanimate objects (natural and manmade objects other than humans and animals).

The reference images were impaired with Gaussian blur and JPEG compression, resulting in 158 images of medium and low quality for each of the impairment type. We conducted subjective experiments asking users to evaluate the visual quality of these images. The JPEG images were evaluated with a 5-point discrete ACR-labeled rating scale in a controlled laboratory setup, while the blur images were evaluated with a 100-point continuous ACR-labeled rating scale in a crowdsourcing setup.

We provide the image files, as well as the collected mean opinion scores (MOS), standard deviation of opinion scores (SOS), corresponding scene and object category labels, and impairment level of every image.
