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...
Dynamic Background Subtraction Based on Local Dependency Histogram
Dynamic Background Subtraction Local Dependency Histogram
2013/7/17
Traditional background subtraction methods perform poorly when scenes contain dynamic backgrounds such as waving tree, spouting fountain, illumination changes, camera jitters, etc. In this paper, a no...
Histogram of Gabor Phase Patterns (HGPP): A Novel Object Representation Approach for Face Recognition
Gabor Phase Patterns Representation Approach Face Recognition
2010/12/16
A novel object descriptor, histogram of Gabor phase pattern (HGPP), is proposed for robust face recognition. In HGPP,the quadrant-bit codes are first extracted from faces based on the
Gabor transform...

Spatial Histogram Features for Face Detection in Color Images
Spatial Histogram Features Face Detection in Color Images
2010/12/14
This paper presents a novel face detection approach in color images. We employ spatial histograms as robust features for face detection. The spatial histograms consist of marginal distribution of colo...
