To improve the color reproduction accuracy of image among digital devices in spectral color reproduction, a novel profile connection space is proposed. The profile connection space is composed of three sets of tristimulus determined by the principal components of typical illuminants and CIE1931XYZ standard colorimetric observer. The spectral reflectance of three common used atlases is transformed to three deformations of the profile connection space, and then transformed back to the spectral reflectance. The color difference between the original and transformed reflectance are very small for the common used illuminants, which indicates that the profile connection space is a good candidate for spectral color reproduction.

为了改善差分灰狼预测算法的早熟收敛、搜索能力不均衡、容易陷入局部最优等问题,提出了一种改进的混合灰狼优化(HGWO)预测算法,可自适应改进和调整差分进化中的变异算子、交叉算子和变异策略。嵌入具有分类预测功能的支持向量机(SVM),同时引入莱维飞行全局搜索更新狼群位置,优化SVM核函数参数γ和惩罚因子C,构建了HGWO-SVM预测算法预测推焦车大车道内物体的运动轨迹。结果表明,与已有算法相比,该算法对行人、自行车、电瓶车、电动三轮车、大中小型四轮汽车的位置预测相对实际值的误差分别降低了4.21、4.14、7
