2012-06-29 10:55:07 -0600 | asked a question | Performance issues on porting warpPerspective into my project Hello all, I wanted to create a modified version of OpenCV warpPerspective to run on my tablet. To begin, I downloaded the OpenCV source code, located the warpPerspective function inside the imgwarp.cpp and copied it into mine JNI file. I changed the arguments as follows: This function is working as it is. But a noticeable performance loss occurs when comparing with the original warpPerspective. Can anyone explain me why is this happening? Could it be the way it is being compiled?I am really struggling with this and have no idea.... Thank you! |
