统计直方图 meaning in English

histogram

The paper is an attempt to put forward fitting julyk distribution curve by statistic histogram curves fitting based on area constraint and to estimate whether sample data meet normal distribution or not
摘要提出利用基于面积约束的统计直方图密度拟合方法把试卷成绩样本数据拟合成一条连续的曲线，并判断样本数据是否符合正态分布。
The simulation result has indicated that using the method of two - value filter can solve the question perfectly , and the question is the edge discontinuity of traditional image classify base on region ; the image fusion which make use of edge gradually change is sententious and efficient ; the color image reinforcing which realized by grey statistics histogram equalization method has reduced the need of environment brightness in virtual photographing system
仿真结果表明，利用二值滤波处理较好地解决了传统的基于区域的图象分类中的边缘不连续的问题；利用边缘渐变方式实现的图像融合简洁有效；由灰度统计直方图均衡所实现的彩色增强处理降低了虚拟照相系统对环境照度的要求。
