Based on the Reserve Database of Mineral Resources in China (1997), this paper established the geological model, grade model, tonnage model and grade-tonnage model of 394 placer gold deposit s in China, which involve frequency histograms and cumulative frequency distributing graphs.

依据"1997年全国矿产储量数据库"资料，对全国 394个砂金矿床建立了地质模型、品位模型、吨位模型、吨位—品位联合模型，模型类型包括频率直方图、累积频率分布图；分别总结了砂金矿床品位及吨位分布的典型数学地质特征。

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。

Another way of presenting these data is by a histogram or frequency distribution.

另一种展示这些数据的方法是通过直方图或者频率分布。

The frequency polygon is simpler than its histogram counterpart.

频率多边形比直方图更简单。

Then, if there are a plurality of characteristic areas, each of which is characterized by the high frequency in the luminance histogram, a characteristic emphasis circuit ( 7 ) performs grayscale extension processing for the plurality of characteristic areas.

而且，特征强调部(7)在检测出的亮度直方图的频率频度多的特征区域为多个的情况下，对于该多个特征区域进行灰度等级扩展处理。

The present invention provides a technique for performing gamma correction processing when there are a plurality of characteristic areas, each of which is characterized by the high frequency in a luminance histogram to improve the impression of contrast.

要約 本发明根据对应亮度直方图的频率频度多的特征区域为多个的情况，进行灰度系数校正处理，提供可改善对比度感的技术。

A histogram showing the frequency of genome sizes for these 2802 species reveals a strongly skewed distribution with a very small modal size of 0-7 pg ( 675 Mbp), well within the bottom I % of the ange.

直方图显示频率的基因组大小为这些为2802种，揭示了强烈的分配倾斜与一个很小的模态的大小0-7编号（ 675人的MBP ），以及内部的底部i ％的昂热。
