包路径：org.opencv.core.Core
类名称：Core
方法名：split

Core.split介绍

[英]Divides a multi-channel array into several single-channel arrays.

The functions split split a multi-channel array into separate single-channel arrays:

mv c = src(I)_c

If you need to extract a single channel or do some other sophisticated channel permutation, use "mixChannels".
[中]将多通道阵列划分为多个单通道阵列。
函数split将多通道阵列拆分为单独的单通道阵列：
mv[c]（I）=src（I）\u c
如果需要提取单个通道或进行其他复杂的通道排列，请使用“混合通道”。
