With the introduction of several new coding tools and technology for depth maps in 3D-HEVC, the coding efficiency is improved at the expense of computational complexity. Meanwhile, the inter-view correlation is not considered and used well for depth maps, while it is developed maturely in texture video coding. Therefore, in this paper, we propose an early determination scheme for the best prediction...
This brief presents a hybrid structure to effectively compute the variable-length Fourier transform by employing the recursive and radix-22 fast algorithm. After applying a hardware-sharing scheme to both fast algorithms, the proposed method not only improves the drawback of higher hardware cost in implementation but also retains the regular and flexible nature of recursive discrete Fourier transform...
Infeasible paths increase program complexity and program redundancy, generate useless DU(def-use) chains, and affect the result of program static analysis. Based on the valid information produced in the process of program compilation, this paper presents a translucent technique to analyze infeasible paths. It first requires the complier construct an information pool for each judge node and variables...
As one type of stealthy and hard-to-detect attack, low-rate TCP-targeted DDoS attack can seriously throttle the throughput of normal TCP flows for a long time without being noticed. The Power Spectral Density (PSD) analysis in frequency domain can detect this type of attack accurately. However, computational complexity of PSD analysis makes it impossible for software implementation at high speed network...
