Fast and efficient blind image quality index in spatial domain. Issue 18 (1st August 2013) - Jiao, Shuhong
Abstract : A fast and efficient method [fast efficient blind (FEB)] for no‐reference image quality assessment (IQA) is presented. Two new features, log‐energy and variance, are proposed in the spatial domain, which make the IQA algorithm faster and more efficient. FEB obviates the training process of distortion images and subjective opinion scores due to the properties of the new features. The experiment shows that the proposed method outperforms conventional methods in terms of both accuracy and execution speed and is also consistent with the subjective assessment of human beings. Owing to the simplicity of the features proposed, FEB can realise real‐time IQA completely.
