We’ve all experienced two hugely frustrating things on YouTube: our video either suddenly gets pixelated, or it stops entirely to rebuffer.Both happen because of special algorithms that break videos i...
Random Partial Paired Comparison for Subjective Video Quality Assessment via HodgeRank ∗
Subjective Video Quality Assessment HodgeRank, Random Graphs Persistence Homology

Subjective visual quality evaluation provides the groundtruth and source of inspiration in building objective visualquality metrics. Paired comparison is expected to yieldmore reliable results; howeve...
Coarse-to-Fine Dissolve Detection based on Image Quality Assessment
dissolve detection coarse-to-fine image quality assessment dissolve length normalization shot boundary detection
2013/7/24
Although many approaches have been proposed for video shot boundary detection, dissolve detection remains an open issue. For a dissolve, we could find that the video frames reveal a “clarity–blur–cl...
WINDOW-LEVEL RATE CONTROL FOR SMOOTH PICTURE QUALITY AND SMOOTH BUFFER OCCUPANCY
Rate Control Smooth Picture Quality ½ - domain Window Buffer Occupancy

Many sophisticated schemes are springing up recently with better characteristics, such as higher capacity and better security. However, if we tune the size of the secret message progressively, most me...
CONSTANT QUALITY CONTROL OF WYNER-ZIV FRAMES IN DCT DOMAIN DISTRIBUTED VIDEO CODING
Distributed video coding Constant quality control Greedy algorithm Adaptive uniform quantizer
2013/7/24
For most DCT domain distributed video coding systems, xed uniform quan-tizers are used to quantize all Wyner-Ziv (WZ) frames. However, it leads to uctuantvideo quality because the WZ frame quality is...
Image Quality Assessment Using Spatial Frequency Component
Image quality assessment low spatial component high spatial component HVS
2013/7/16
Image quality assessment (IQA) is a crucial technique in perceptual image/video coding, because it is not only a ruler for performance evaluation of coding algorithms but also a metric for ratio-disto...
Elimination of the Quality Problems Encountered in Mass Production by Using Statistical Quality Control
Statistical quality control Process control X-R control charts
2009/10/12
Having determined the quality problems in mass production in a medium-size firm chosen as a pilot study,all the processes from casting to machining were investigated. The problem of low quality arisin...
