这段代码工作正常,直到最后一行.它将正确的图像保存在磁盘上但在退出函数后显示"内存泄漏" - 堆损坏.我读过Mat不需要明确发布.在我的情况下,它会在释放和w/o释放时崩溃.请帮忙.

void CannyEdgeDetectionFilter::applyFilter(Mat& mat, Mat& mixedBandsMat)
{
    //Mat mixedBandsMat;

    vector<Mat> bandWiseImages;
    split(mat, bandWiseImages);

    //! Evaluate numChannels to be filtered in the input image
    int numChannels = mat.channels();
    int type = mat.type();

    //! Multiplied by 8 to get bits from Bytes
    int singleChannelDepth = 8*mat.elemSize1();

    for (int i = 0; i < numChannels; i++)
    {
        Canny(bandWiseImages[i], bandWiseImages[i], m_LowerThreshold,
            m_UpperThreshold, m_Kernel.rows);
    }

    //! Creating filteredImgMat in order to set DataValues
    mixedBandsMat.create(mat.rows, mat.cols, mat.type());

    //! Unifying the channels back to the …
