Blockiness Estimation in Reduced Reference Mode for Image Quality Assessment [PDF]

open access: yes, 2014
In this paper we present blockiness estimation meter in reduced reference mode using frequency domain analysis. Since blockiness is an abrupt luminance discontinuity at the DCT block boundaries and also has periodic patterns, therefore blockiness ...

IMAGE FUSION AND IMAGE QUALITY ASSESSMENT OF FUSED IMAGES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
It is of great value to fuse a high-resolution panchromatic image and low-resolution multi-spectral images for object recognition. In the paper, tow frames of remotely sensed imagery, including ZY03 and SPOT05, are selected as the source data.

Content-Aware Retargeted Image Quality Assessment

open access: yesInformation, 2019
In targeting the low correlation between existing image scaling quality assessment methods and subjective awareness, a content-aware retargeted image quality assessment algorithm is proposed, which is based on the structural similarity index.

No-Reference Image Quality Assessment Method Based on Visual Parameters

open access: yesJournal of Electronic Science and Technology, 2019
Recent studies on no-reference image quality assessment (NR-IQA) methods usually learn to evaluate the image quality by regressing from human subjective scores of the training samples. This study presented an NR-IQA method based on the basic image visual
