Abstract:

Image definition is an important indicator of digital image quality.Oriented to the application of No\|reference image quality assessment,some representative definition evaluation algorithms are introduced in this paper.In order to accurately and objectively assess each algorithm and to effectively evaluate image definition in the practical application,comparisons and analysis on performance of each algorithm are also done from the following aspects:single peak,no bias,sensitivity; the independence of image size and content; the consistency with subjective perception.Results show the ReBlur and NRSS algorithm have better evaluation performance than other algorithms for the No\|reference image quality assessment.
 

Key words: Image quality, Definition, Performance evaluation
