Vectorising Bitmaps into Semi-Transparent Gradient Layers
Semi-Transparent Gradient Layers Vectorising Bitmaps
2016/5/24
We present an interactive approach for decompositing bitmap drawings and studio photographs into opaque and
semi-transparent vector layers. Semi-transparent layers are especially challenging to extra...
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...
Facial Shape Localization Using Probability Gradient Hints
Boosting facial shape localization maximum a posteriori estimation probability gradient hints
2013/7/16
This letter proposes a novel method to localize facial shape represented by a series of facial landmarks. In our method, the problem of facial shape localization is formulated with a Bayesian inferenc...
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...
