Fine-Grained Quality Assessment for Compressed Images.
IEEE Transactions on Image Processing : a Publication of the IEEE Signal Processing Society 2019 March
Image quality assessment (IQA) has attracted more and more attention due to the urgent demand in image services. The perceptual-based image compression is one of the most prominent applications that require IQA metrics to be highly correlated with human vision. To explore IQA algorithms that are more consistent with human vision, several calibrated databases have been constructed. However, the distorted images in the existing databases are usually generated by corrupting the pristine images with various distortions in coarse levels, such that the IQA algorithms validated on them may be inefficient to optimize the perceptual-based image compression with fine-grained quality differences. In this paper, we construct a large-scale image database which can be used for fine-grained quality assessment of compressed images. In the proposed database, reference images are compressed at constant bitrate levels by JPEG encoders with different optimization methods. To distinguish subtle differences, the pair-wise comparison method is utilized to rank them in subjective experiments. We select 100 reference images for the proposed database, and each image is compressed into three target bitrates by four different JPEG optimization methods, such that 1200 distorted images are generated in total. Sixteen well-known IQA algorithms are evaluated and analyzed on the proposed database. With the devised fine-grained IQA database, we expect to further promote image quality assessment by shifting it from a coarse-grained stage to a fine-grained stage.
