At first, the image background is suppressed by setting a threshold. Then, both gray density and gray interval of the histogram are equalized.
该算法首先通过设置平台阈值对背景的增强进行抑制，然后将直方图在灰度密度和灰度间距两个方向进行均衡处理。
The common frequency histogram method is not applicable to analyze the small sample data, because it is sensitive to the analysis parameters such as the starting point and the interval step.
在应用频率直方图法对小样本数据进行处理时，分析结果对直方图的起点、区间步长以及样本中的奇异数据十分敏感。
The response is fairly self-explanatory, but it should be noted that the histogram keys correspond to the lower boundary of the interval.
响应是能够对其意义进行解释的，但是值得注意的是histogram键对应的是间隔的下边界。
