用于相似颜色图像检索，传统直方图法，巴氏系数法，传统欧式距离法-For the image similarity graph, the traditional histogram Bhattacharyya coefficient method, traditional Euclidean distance method

灰度图像直方图比较，在做预处理时，比较灰度图像的相似度，在做图像相似度比较方面可以使用。-Gray-scale image histogram comparison, during preprocessing, similarity compare grayscale image, making the image similarity comparisons can be used.

软件用于分析给出图片的颜色直方图，可以进一步改进，用来分析两张图片的相似度（后期自己完成即可）(The software is used to analyze the color histogram of the picture, which can be further improved to analyze the similarity of the two pictures (later completed by themselves).)
