In recent times, DSP algorithms have received increased attention due to rapid advancements in multimedia computing and high-speed wired and wireless communications. In response to these advances, the search for novel implementations of arithmetic-intensive circuitry has intensified. For the portability requirement in telecommunication systems, there is a… (More)
Removal of noise uses various natural image priors, including gradient based, sparse representation-based and nonlocal self similarity-based ones. The existing denoising algorithm tends to smooth the fine scale image textures, when removing noise, it degrades the image visual quality. To address this problem, a texture enhanced image denoising method is… (More)
In the title compound, C(12)H(14)O(2)S(3), a chain transfer agent (CTA) used in polymerization, the dihedral angle between the aromatic ring and the CS(3) grouping is 84.20 (10)°. In the crystal, carb-oxy-lic acid inversion dimers linked by pairs of O-H⋯O hydrogen bonds generate R(2) (2)(8) loops.
In the title compound C(33)H(30)S(6), the three pendant methyl-ene benzodithio-ate groups lie to one side of the central benzene ring in a cis-cis-cis 'tripod' arrangement. The dihedral angles between the central benzene ring and the three pendant rings are 72.54 (4), 89.68 (4) and 86.74 (4)°. In the crystal structure, one of the benzene rings is disordered… (More)
This paper proposes a pipelined, systolic architecture for two-dimensional discrete Fourier transform (DFT) computation which is highly concurrent. The architecture consists of two, one-dimensional DFT blocks connected via an intermediate buffer. The proposed architecture offers low latency as well as high throughput and can perform both one-and… (More)
