我正在尝试在studio 2013和opencv 2.4中实现SIFT。我收到以下错误。
OpenCV Error: Assertion failed (dims <= 2 && data && (unsigned)i0 < (unsigned)size.p[0] && (unsigned)(i1*DataType<_Tp>::channels) < (unsigned)(size.p[1]*channels()) && ((((sizeof(size_t)<<28)|0x8442211)
((DataType<_Tp>::depth) & ((1 << 3) - 1))*4) & 15) == elemSize1()) in unknown function, file C:\opencv231\build\include\opencv2/core/mat.hpp, line 552
我认为错误出现在以下代码中：

for (yiter = 1; yiter < middle.rows-1; yiter++)
{
for (xiter = 1; xiter < middle.cols-1; xiter++)
{
cout << i << " " << j << " " << yiter << " " << xiter<< " "<<endl;
double currentPixel = middle.at<uchar>(yiter, xiter);

代码正在打印“IN findmaxmin” 0 1 1 1 然后发生错误。我通过注释掉这个函数检查了剩下的代码，代码工作正常。
