The exponential growth of online videos imposes urgent demands on near-duplicate video detection. Near-duplicate keyframe detection is at the base of near-duplicate video detection. In this paper, based on the analysis of the state-of-the-art of near-duplicate keyframe detection, GrayScale Pyramid (GSP) is processed for improving the global feature of color histogram. By constructing the spatial pyramid...
A new criterion is proposed in this paper which employs the grayscale erosion to measure the concentration of different time-frequency representations/distributions. In contrast to some widely used Concentration Measures proposed by L. Stankovic and L. Jones, this method combines the both width and peakedness information of the auto-term area. Moreover, it can be used in the multi-component signal...
The display quality improvement of electrophoretic paper largely depends on the increase in the number of grayscale, but it will make drive mode design complicated. The inhibition of residual driving voltage also becomes more difficult. This paper presents a new 16 gray-scale driving schema based on the DC-balance principle, improve the display quality of electrophoretic display (EPD). The display...
