图像颜色特征提取（三阶矩）完整代码；stricker和0reng0提出了颜色矩的方法，颜色矩是一种简单有效的颜色特征表示方法，有一阶矩(均值)、二阶矩(标准差)和三阶矩(斜度)等，由于颜色信息主要分布于低阶矩中，所以用一阶矩，二阶矩和三阶矩足以表达图像的颜色分布，颜色矩已证明可有效地表示图像中的颜色分布
Image color feature extraction (three moments) complete code;Stricker and 0reng0 proposed a method of color moments. Color moments are a simple and effective color feature representation method. There are first order moment (mean), two order moment (standard deviation) and three order moment (slope). Because the color information is mainly distributed in the low order moment, the color distribution of the image is expressed with the first moment, the two order moment and the three order moment. Color moments have proved effective in representing color distribution in images. (2018-04-26, matlab, 1KB, 下载12次)
