raw color feature

The colour feature extracted by the aforementioned colour feature extraction method (refer to Method: Colour feature extraction section), is also available as the file colour_feature_raw.xlsx, where post-processing by calculating the mean (μ) and standard deviation (s) can be found in the file colour_feature_processing.xlsx.

通过前述颜色特征提取方法（参见「方法：颜色特征提取」章节）提取得到的颜色特征，可通过文件colour_feature_raw.xlsx获取；其中经计算均值（μ）与标准差（s）完成的后处理结果，可于文件colour_feature_processing.xlsx中获取。
