采用图像分块的局部直方图方法考虑了颜色的位置信息，但却不具有旋转、平移不变性。

The local histogram partitioning an image into regions takes the spatial features into account, but fails to find rotated or translated images that are similar to query images.

对于颜色特征，计算图像颜色的局部累加直方图，同时提取分块的颜色矩弥补其不包含颜色空间分布关系的缺点。

To represent color feature, local color cumulative histogram is computed, we also extract the color moments of partitions to solve the problem of lacking the spatial knowledge.
