Application Specific Processor Design for Dct Based Applications
, 2015 Discrete Cosine Transform (DCT) is used in JPEG compression, image encryption, image watermarking and channel estimation. In this paper, an Application Specific Processor (ASP) for DCT based applications is designed and implemented to Field Programmable ...

Moving object segmentation in DCT-based compressed video [PDF]
, 2000 A block-based automatic segmentation algorithm has been developed for detecting and tracking moving objects in DCT-based compressed video. The proposed algorithm segments moving objects with block resolution using the stochastic behaviour of the image ...

TT4D: Tensor‐Train‐based 4D Time‐Dependent Volume Rendering
Computer Graphics Forum, EarlyView.Abstract Visualizing large‐scale, time‐varying volumetric data using direct volume rendering remains a significant challenge in scientific visualization, particularly as data sizes and resolutions continue to increase. One promising direction for addressing this challenge is the use of tensor decompositions, which have proven to be a useful tool for ...

DCT based pseudo complex cepstrum
, 2002 We propose two algorithms, which effectively use Discrete Cosine Transform (DCT) to obtain complex cepsrrum, which we call as the Discrete Cosine Transformed Cepstrum (DCTC), The first algorithm uses the relation between Discrete Fourier Transform (DFT ...

Cell Proliferation, EarlyView.The hfPSC‐LCs could be established from naïve hESCs, conventional hESCs, hiPSCs, and human blastocysts. The hfPSC‐LCs hold robust capacity for three germ layers, hPGCLCs, and hALPCs. ABSTRACT Human embryos undergo pivotal morphogenetic remodelling shortly after implantation. The understanding of this crucial stage is severely impeded by the scarcity of

DSDWA: A DCT-based Spatial Domain Digital Watermarking Algorithm
, 2014 DCT-based transformed domain watermarking algorithm has some flaws In the aspects of embedding position, embedding strength and embedding method, which have an important influence on watermarking embedding and watermarking extracting.

Ecological Entomology, EarlyView.Short‐ and long‐term expression of PPO‐D, PI‐IIc and PR‐1a were assessed in intact plants and detached tomato leaves of two varieties infested with Tetranhycus urticae. Tomato defences were induced in both intact and detached leaves, but the induction levels varied with plant variety and gene assessed.

European Journal of Oral Sciences, EarlyView.Abstract The APOE4 gene, particularly the ε4 allele, is linked to susceptibility to Alzheimer's disease, and periodontitis can cause pathological changes in multiple organs, but combined effects of these conditions and the impact of tumor necrosis factor (TNF)‐α regulation on the combined effects remain unclear.

Variable temporal length 3D DCT-DWT based video coding
, 2007 Almost all variable length 3D-DCT algorithms employ thresholds. Although the selection of threshold considerably affects the algorithm performance, there is no framework to choose them effectively.

The FEBS Journal, EarlyView.Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...
