The class Mat represents an n-dimensional dense numerical single-channel or multi-channel array. It can be used to store real or complex-valued vectors and matrices, grayscale or color images, voxel volumes, vector fields, point clouds, tensors, histograms (though, very high-dimensional histograms may be better …

If threads == 0, OpenCV will disable threading optimizations and run all it's functions sequentially. Passing threads < 0 will reset threads number to system default. This function must be called outside of parallel region.

The conversion from Mat depth 7 to 5 does not exist in opencv. This is the the function func that you see in cv_assert. This is the function that determines the function which is used for conversion. It checks the array cvtTab. (ddepth is 5, sdepth is 7) As you can see cvtTab [5] [7] is 0, so cv_assert will fail.
