I need to use the retina model in OpenCV. And I find the model exist both in OpeCV2.x and OpenCV3.x. Which version should I choose? Maybe the models in different versions are the same? Could somebody help me?

choose 3.x. (2.4 is like 5 years behind in development, and will only receive bugfixes)

while building latest opencv3 sources (and you'd need opencv_contrib, too !) might be a bit more work, you'll gain a lot of functionality (e.g. ocl support for the retina)

Thanks! I have tried the model in 2.4.13 and 3.0.0, and find little difference between the output of parvo and magno. So, if just use the original retina filter model output (output_parvo and output_magno), may I believe the models in different versions are same? Perhaps the original retina filter outputs in different versions are different in actually?
