2016-12-29 11:33:12 -0600 | asked a question | Why MORPH_ELLIPSE kernel is slower than MORPH_RECT and others? I was doing some dilation and erosion operations and noticed that MORPH_ELLIPSE kernel takes much more time than MORPH_RECT and MORPH_CROSS kernel. A similar question and finding is also posted in StackOverflow here. Can somebody tell why this is so? |
2016-03-12 02:51:33 -0600 | asked a question | OpenCV Java code running faster than OpenCV native C++ code I have written two versions of an android application using OpenCV. OpenCV is being used for following operations:
The first version of the application does all these operations in Java and takes around 200 ms. However, the native implementation takes around 700 ms! Moreover, I also measured the timings of Java implementation on Nexus 5 and Nexus 6 and I got following results: Nexus 5: Java: 200 ms, C++: 700 ms! Nexus 6: Java: 180 ms, C++: 900 ms! Can somebody please explain why this is happening? Isn't the native implementation supposed to run faster? |
2016-03-08 08:16:31 -0600 | asked a question | opencv4android static libraries to shared libraries I downloaded OpenCV4Android 3.1.0. All the native libraries in jni folder are static ('.a' extension). However, the tutorials I am following for using opencv in Android Studio are using shared libraries ('.so' extension). Do I have to convert the static libraries to shared? How? |

2015-12-03 04:00:54 -0600 | asked a question | seamless cloning in opencv3.0 without specifying point in destination image Hi! I have two images of a scene (A and F) and a mask. Images A and F are aligned. I want to do a seamless cloning of the part inside mask from image A to image F (at the same location). However, the seamlessClone() requires a parameter - Point as an argument to indicate where to copy the object. How can I achieve my goal? |
