A NO-REFERENCE PERCEPTUAL BLUR METRIC USING HISTOGRAM OF GRADIENT PROFILE SHARPNESS
image quality assessment blur metric gradient profile just noticeable distortion
2013/7/16
No-reference measurement of blurring artifacts in images is a challenging problem in image quality assessment field. One of the difficulties is that the inherently blurry regions in some natural image...
A No-Reference Blocking Artifacts Metric Using Selective Gradient and Plainness Measures
Blocking artifacts metric gradient measures plainness measures
2013/7/17
This paper presents a novel no-reference blocking artifacts metric using selective gradient and plainness (BAM_SGP) measures for DCT-coded images. A boundary selection criterion is introduced to dist...
