As a key component in many computer vision systems, optical flow estimation, especially with large displacements, remains an open problem. In this paper we present a simple but powerful matching method works in a coarse-to-fine scheme for optical flow estimation. Inspired by the nearest neighbor field (NNF) algorithms, our approach, called CPM(More)
IgG monoclonal antibodies (mAbs) consist of two Fab fragments and one Fc fragment. The Fab fragments contain the variable regions and are responsible for drug specificity (via antigen binding); the Fc fragment contains constant regions and is responsible for effector functions (via interactions with Fcγ receptors) and extended serum half-life (via(More)
Methionine oxidation commonly occurs in the Fc fragment of therapeutic monoclonal antibodies; however, its impact on antibody function has not been addressed. Using surface plasmon resonance and cell binding assays, we examined the impact of methionine oxidation on the binding of two humanized IgG1 antibodies to Fc gamma receptors (Fc gammaR) and to the(More)
In this paper, a novel architecture for an MQ arithmetic coder with high throughput is proposed. The architecture can process two symbols in parallel. The main characteristics are eight process elements for the prediction of probability interval A, the combination of calculation units for the code register C with the Byteout&Flush procedure, and the use of(More)
Fractional motion estimation (FME) significantly enhances video compression efficiency, but its high computational complexity also limits the real-time processing capability. In this paper, we present a VLSI implementation of FME design in High Efficiency Video Coding (HEVC) for ultra-high definition video (Ultra-HD) applications. We firstly propose a(More)
The import of disaccharides by many bacteria is achieved through their simultaneous translocation and phosphorylation by the phosphoenolpyruvate-dependent phosphotransferase system (PEP-PTS). The imported phospho-disaccharides are, in some cases, subsequently hydrolyzed by members of the unusual glycoside hydrolase family GH4. The GH4 enzymes, occasionally(More)
Spectral unmixing amounts to automatically finding the signatures of pure spectral components (called endmembers in the hyperspectral imaging literature) and their associated abundance fractions in each pixel of the hyperspectral image. Many algorithms have been proposed to automatically find spectral endmembers in hyperspectral data sets. Perhaps one of(More)
In this paper, a novel visual tracking method based on random ferns and random projection has been proposed. Instead of a binary comparison in the standard random ferns method, a subtraction is used in the proposed method. Different subtraction results are projected into a single real value by the random projection. The real value from the subtraction is(More)
This study explores the use of the graphics processing units (GPUs) for performing the two-dimensional discrete wavelet transform (DWT) of images. The study of fast wavelet transforms has been driven both by the enormous volumes of data produced by modern cameras and by the need for real-time processing of these data. With the emergence of general computing(More)
