| Performance comparison for Convolution - Direct vs FFT vs Auto[Forums] Hi,This is regarding the comparison of Direct Mode vs FFT mode for Multi-dimensional convolutions in terms of performance. My expectation was that the FFT mode should be faster than direct mode, but it... Posted: 2012-04-10 13:28:52 | convolution, FFT, MKL 10.3 |
| Optimal 3D representation???[Forums] What would be the most efficient way of representing a 3D object?In my application I'll need to apply convolution to a 3D object; this is not a problem for 1D or 2D:1D.
