基于双边滤波的高斯金字塔变换Retinex图像增强算法 ... 信息丢失、区域不清晰以及雾气遮挡等问题,提出了一种基于双边滤波的高斯金字塔变换Retinex图像增强算法,以提高雾天图像的对比度。首先,基于空间域核函数和像素差,建立了改进的双边滤波函数数学模型。然后,将输入图像转换为HSI(Hue,Saturation,Intensity)图像,用改进的双边滤波函数代替原算法中的高斯函数,从亮度图像(I色彩空间)中提取反射分量,以获得保持边缘且不受亮度影响的反射图像。最后,通过高斯金字塔降采样,获取不同尺度的彩色图像,用改进的Retinex算法对多种尺度的图像进行增强, ...
Frequency stabilization and tuning of breathing solitons in Si ... , and metrology. Breathing solitons are a particular kind of dissipative Kerr soliton in which the pulse duration and peak intensity show periodic oscillation. Here we have investigated the breathing dissipative Kerr solitons in silicon nitride (
Plasmonic resonance-linewidth shrinkage to boost biosensing Coupling effects of surface plasmon resonance (SPR) induce changes in the wavelength, intensity, and linewidth of plasmonic modes. Here, inspired by coupling effects, we reveal an abrupt linewidth-shrinking effect in 2D gold nanohole arrays at the ...
Real-time observation of vortex mode switching in a narrow-linew... ... mode-locked pulses. Recently, optical vortex beams have been extensively investigated due to their quantized orbital angular momentum, spatially donut-like intensity, and spiral phase front. In this paper, we have demonstrated the first to our kno

The mechanisms of electromagnetic field generation are analyzed and considered as a function of the intensity and the spectral range of emissions they produ

The twist effect on multimode fiber is used as an example herein. Experimental results show that light intensity through

Metasurfaces are versatile, novel platforms for manipulating the scattering, color, phase, or intensity of light. Currently, one of the typical approaches for designing a metasurface is to optimize one or two variables ...
