| 2012-12-15 06:01:30 -0600 | answered a question | How the descriptor pattern of FREAK is defined? I found my response. The pattern in the OpenCV implementation is defined to obtain a layout like the one described in the paper, with 43 Gaussians, 6 for every size except for the central one, and a response similar to the retina. However, there isn't a right way build such a pattern as long as the retinas response and the ganglion cells distribution are reproduced. |

| 2012-12-11 18:10:12 -0600 | asked a question | How the descriptor pattern of FREAK is defined? Hi I've been looking for some documentation of how the FREAK descriptor pattern is build, but neither the original paper nor the OpenCV implementation have information more than the implementation itself. My question is, someone knows or have information about how is this defined? |
