While video watching is now an indispensable part of the general public media consumption, yet very little is knownabout the relationship between how users interact with each otherand how that affects video consumption patterns. In this paper, weexplore the relationship between user commenting behavior andhow that might or might not be predictive of video consumptionpatterns such as watch time. Contrary...
This paper proposed a new approach used for tracking multi-pith within one mixture speech signal. In this method, we employed a novel continuous correlation feature for calculating pitch model. This feature not only represents the harmonicity but also includes the information of spectral continuity, and hence improving the accuracy of the multi-pitch estimate. A DBNs and HMM hybrid model was further...
When digital forgery is introduced in a digital images, in order to create a convincing match, it always includes operation of scaling, rotation or skewing, which procedures typically require resampling and interpolation step. However, the resampling detection is always severely affected by the blocking artifacts introduced by JPEG compression. In order to solve this problem, in this paper an effective...
A right marketing investment has a significant impact to customer equity management. By assuming the relevant conditions, this paper analyses desired rate of return, risk volatility and risk preference of marketing investment. Based on analysis of marketing investment to two customer groups, this paper further describes marketing portfolios and determines a best marketing portfolio for multiple customer...
Image denoising has been being a hotspot in the discipline of image processing. In this paper, we first analyze the intra-scale distribution and inter-scale distribution characteristics of the coefficients at finer-scale of the noise image, and then propose an edge detection method for preserving important high frequency information through incorporating the coefficients correlation of intra-scale...
A salt & pepper noise fast filtering algorithm for grayscale images based on neighborhood correlation detection is presented. By utilizing a 4×4 pixel template, the algorithm can discriminate and filter various patterns of salt & pepper noise spots or blocks within 2×2 pixel size range. In contrast with many kinds of median filtering algorithm, which may cause image blurring, it has much higher...
