Multiple radar systems represent an attractive option for target tracking because they can significantly enlarge the area coverage and improve both probability of trajectory detection localization accuracy. The presence multiple extended targets or weak is a challenge systems. Moreover, their performance may be severely deteriorated by regions characterized high clutter density. In this paper, algorithm targets, weak, based on measurements provided radars in environment with heavily...
Surrogate safety measures are widely used in advanced driver assistance systems (ADASs) to detect traffic conflict and evaluate risk levels car-following scenarios. However, the integration of driving style into surrogate has not been thoroughly investigated. To enhance reliability user satisfaction ADASs, this study introduces a measure, deceleration (RD), describe drivers’ perception decision-making process process. The parameters RD calibrated using genetic algorithm better reflect...
In recent years, multi-extended-targets detection in sea clutter has gained a special interest. Dynamic programming based track-before-detect (DP-TBD) algorithm is used to detect extended targets video data of high resolution radars. Two innovations are presented this work.

Both principle DP-TBD and its detail...
Deep learning algorithms have made significant progress in dynamic scene deblurring. However, several challenges are still unsettled: 1) The degree and scale of blur different regions a blurred image can considerable variation large range. the traditional input pyramid or downscaling-upscaling, is designed to limited inflexible perceptual variousness cope with variation. 2) nonlocal block proved be effective enhancement tasks, but it requires high computation memory cost. In this paper, we...
Abstract Inpainting high-resolution images with large holes challenges existing deep learning-based image inpainting methods. We present a novel framework—PyramidFill for inpainting, which explicitly disentangles the task into two sub-tasks: content completion and texture synthesis. PyramidFill attempts to complete of unknown regions in lower-resolution image, synthesize textures higher-resolution progressively. Thus, our model consists pyramid fully convolutional GANs, wherein GAN is...
Acute laboratory toxicity tests were carried out to assess the individual and combined toxic effects of metals including cadmium (Cd), lead (Pb) metalloid arsenic (As) in Phaeozem on seed germination seedling growth soybean, Glycine max Seeds exposed varied concentrations Cd, Pb As individually mixtures Cd + Pb, As, As.
