查询词典 luminance

First,image structure vector field is derived from source luminance orthonormal vector sets. Andusing neighbor vectors to improve the weak gradient fields produces the structure vectorfield that is needed by LIC rendering. Then, LIC convolution step-length is adjustedaccording to local curvature in the structure vector field. LIC convolution length iscalculated according to the local statistical characteristics of the texture image. Finally, thealgorithm transfers the reference image\'s color characteristics to the rendering result tomake it full of rich color like oil paintings.

该算法通过计算源图像亮度分量的切矢量产生图像的结构矢量场，并对弱矢量区域进行邻域填充处理，获得LIC绘制所需的结构矢量场；然后，根据结构矢量场的局部曲率特征调整LIC的积分步长，并根据纹理参考图像的局部统计特征，自适应地改变LIC的积分长度；最后，将颜色传输算法引入LIC绘制结果，对绘制效果颜色进行渲染。

In the video segmentation method based on DEMD, the intrinsic mode function with the lowest frequency is discarded and a simple and effective motion compensation method is adopted. As a result, the video segmentation method is no longer sensitive to abrupt change of luminance, object motion in shots, motion and zoom in/out of cameras, so that the precision of detecting shot boundaries is improved.

基于DEMD的视频分割方法除去视频帧中反映图像内光照分布与能量的最低频率固有模态函数(intrinsic mode function，IMF)分量，并选择一种简单有效的运动补偿方法，解决了传统基于直方图方法对光照突变、镜头内物体运动和镜头运动及拉伸的敏感问题，减少了镜头边界识别的误检率，在保证召回率不受影响的前提下提高了视频分割的精确度。

On the basis,a luminance difference of current Kirchhoff equation was established.

在此基础上，建立了亮度差的基尔霍夫电流方程，由此将亮度计算问题转化为电路模型求解的问题。

The shape information of surveillance objects is represented as macro-block coordinates. The temporal redundancy is eliminated by motion estimation within the surveillance region in the reference frame. Since the number of luminance levels is reduced due to enhancement process, the residual error of motion estimation is compressed with lossless entropy coding.

监控对象的形状信息表示为宏块坐标；监控对象之间的时间冗余通过运动估计来消除，但搜索范围限制在前一帧监控对象区域之内；由于增强处理使得监控区域的灰度级减少了，所以对运动估计的残差进行无损熵编码。
