Recently, low-rank representation (LRR) based methods have been used for hyperspectral image (HSI) denoising, which can simultaneously remove different types of noise: Gaussian noise, impulse noise, dead lines, and so on. However, the LRR based method does not make full use of the spatial information in HSI. In this paper, we integrate the superpixel segmentation (SS) into the LRR, and propose a novel...
Infrared (IR) small target detection with high detection rate, low false alarm rate, and multiscale detection ability is a challenging task since raw IR images usually have low contrast and complex background. In recent years, robust human visual system (HVS) properties have been introduced into the IR small target detection field. However, existing algorithms based on HVS, such as difference of Gaussians...
The evaluation pattern that risk degree is a product of danger degree and vulnerability were introduced based on natural disasters risk expression recommended by the Humanitarian Affairs Department of United Nations. The transformed values function were put out to transfer overtopping probability into danger degree, which were measured on a scale of 0 to 1. "Property index" and "population...
