Then partial least squares method was used for selecting the effective wavelength interval of illumination. 然后应用偏最小二乘法选择合适的光源波段间隔。
The experimental results show that this algorithm is robust to the partial occlusions, scale-change illumination and variations. 仿真结果表明,该方法对环境光照变化、目标尺寸变化、局部遮挡等均具有一定的鲁棒性。
The result shows that the set-up noise can be restrained and the output SNR can be improved considerably by using broad band temporally partial coherent illumination. 结果表明,时间部分相干照明可以提高系统的输出信噪比,对系统的装置噪声有明显的抑制作用。
In this paper, the theory and the method of Fractional Fourier Filtering applied to improve the image quality by the partial coherent illumination have been established. 本论文初步建立了分数傅立叶域滤波改善部分相干成像质量的理论、方法和滤波器优化设计算法。

To overcome the disadvantages, A freeform reflector design method, which is mainly based on a first-order quasi-linear partial differential equation, is proposed in this article for uniform rectangular illuminance distribution in the field of LED illumination. 为了克服该设计方法的缺点,本论文在文献调研的基础上,建立了点光源的非成像光学设计模型,提出了一种基于一阶拟线性偏微分方程的自由曲面反射器设计方法。
Compared with the global features, the local features are more distinctive, invariable and robust. Thus, the local features are more adaptive when the image has blur background, partial occlusion or illumination changes. 与传统的图像全局特征相比,图像的局部特征具有更好的唯一性、不变性和鲁棒性,能更好的适应图像背景混杂、局部遮挡、光线变化等情况。
Study the reasons, the first partial differential equation can directly image gradient, tangent, and other illumination, curvature and other geometric information; they can effectively simulate isotropic diffusion, anisotropic diffusion of information transmission mechanism. 研其原因,首先偏微分方程能直接处理图像中的梯度,切线,等照度线,曲率等几何信息;又可以有效的模拟各向同性扩散,各向异性扩散的信息传输机制。
