A No-reference Blur Image Quality Assessment Algorithm Based on Wavelet High Frequency Singular Value Decomposition
摘要
Abstract
Traditional no reference blur image quality assessment methods usually need a pre-training and learning or a reference image constructing procedure,this result in the algorithm with high computa-tion cost.Aiming to this,a simple and effective no reference blur image quality assessment algorithm is proposed based on wavelet high frequency coefficients singular value decomposition.The method is build on the observations that the different wavelet high frequency sub-bands in the same scale of an image are highly structural correlation,and the degree of correlation would be reduced as the blur distortion deepe-ning.According to this,the new method first makes wavelet transform to the image,then makes singular value decomposition to the high frequency sub-bands to get their structure information.Finally,the an-gles,which represents the similarity,between different high frequency sub-bands’structural vectors are calculated and the sum of angles is used as the last objective assessment index.Experiments results show its good effectiveness and performance on LIVE2,CSIQ and TID2013databases and compared to the tra-ditional no-reference methods,the proposed algorithm is more efficient and practical as it does not need to train or create a reference image.关键词
