想了解Android基于opencv实现多通道分离与合并的相关内容吗,易冬在本文为您仔细讲解Android opencv实现多通道分离与合并的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:Android,opencv,opencv多通道分离与合并,下面大家一起来学习吧。

多通道分离

API

public static void split(Mat m, List<Mat> mv)

操作

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    mBinding = DataBindingUtil.setContentView(this, R.layout.activity_channel_split_merge)
    mBgr = Utils.loadResource(this, R.drawable.test)
    val imgList = mutableListOf<Mat>()
    Core.split(mBgr, imgList)
    mChannelB = imgList[0]
    mChannelG = imgList[1]
    mChannelR = imgList[2]
}

通道合并

API

public static void merge(List<Mat> mv, Mat dst)

操作

private fun showBGZero() {
    val zero = Mat.zeros(mBgr.rows(), mBgr.cols(), CvType.CV_8UC1)
    val list = mutableListOf<Mat>()
    list.add(zero)
    list.add(zero)
    list.add(mChannelR)
    val result = Mat()
    Core.merge(list, result)
    showMat(result)
    result.release()
}

private fun showBRZero() {
    val zero = Mat.zeros(mBgr.rows(), mBgr.cols(), CvType.CV_8UC1)
    val list = mutableListOf<Mat>()
    list.add(zero)
    list.add(mChannelG)
    list.add(zero)
    val result = Mat()
    Core.merge(list, result)
    showMat(result)
    result.release()
}

private fun showGRZero() {
    val zero = Mat.zeros(mBgr.rows(), mBgr.cols(), CvType.CV_8UC1)
    val list = mutableListOf<Mat>()
    list.add(mChannelB)
    list.add(zero)
    list.add(zero)
    val result = Mat()
    Core.merge(list, result)
    showMat(result)
    result.release()
}

private fun showSwitchBR() {
    val zero = Mat.zeros(mBgr.rows(), mBgr.cols(), CvType.CV_8UC1)
    val list = mutableListOf<Mat>()
    list.add(mChannelR)
    list.add(mChannelG)
    list.add(mChannelB)
    val result = Mat()
    Core.merge(list, result)
    showMat(result)
    result.release()
}
