2014-04-17 03:01:23 -0600 | asked a question | LinearPolar/LogPolar transformation distoring an iris I'm currently running the following Python (OpenCV 3): Input image: / Result:
The problem I'm having is that this creates something distorted; what I expected was the output to be tall and thin, to reduce the amount of data thrown away & interpolation. What can I do to improve the result, and produce a nice, beautiful, detailed iris strip? |

2014-03-29 07:09:08 -0600 | asked a question | Transform Polar to Cartesian co-ordinates? I've written the following python code that 'unravels' an iris from a pupil (i.e. given a central point, it sweeps round 360 degrees and prints out the iris as a long strip (i.e. a rectangle). The problem is, this code is very slow in Python; is there a good way to do this using OpenCV? Input: (Cropped) output: |

2013-10-29 07:03:20 -0600 | commented question | Do you guys have problem using opencv with osx Mavericks? I can't get it to install at all. I'm using brew, and I tried every version 2.4.3 up to 2.4.6.1 - they all fail in the build process somewhere. I tried to download the source of 2.4.5 and manually build that using make, but that failed too. Like you, I'm using Mavericks + Xcode 5.0.1. Did you figure it out? |
