—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)
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)
—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)
—Context-based Adaptive Binary Arithmetic Coding (CABAC) is a well known bottleneck in H.264/AVC encoder. Despite its high performance, the tight feedback loops make it difficult to parallelize. Most researchers are concerned about multi-bin processing regardless of the pipeline design. But without pipeline, the overall performance is greatly limited. In(More)
Extreme learning machine (ELM) is of great interest to the machine learning society due to its extremely simple training step. Its performance sensitivity to the number of hidden neurons is studied under the context of hyperspectral remote sensing image classification. An empirical linear relationship between the number of training samples and the number of(More)
Bacterial persisters, usually slow-growing, non-replicating cells highly tolerant to antibiotics, play a crucial role contributing to the recalcitrance of chronic infections and treatment failure. Understanding the molecular mechanism of persister cells formation and maintenance would obviously inspire the discovery of new antibiotics. The significant(More)
