2015-05-12 10:17:15 -0600	commented answer	Does opencv_traincascades give consistent results over time? Hey, guys. Thanks for your inputs. As for TBB, I have a vanilla Ubuntu 14.04 opencv installation (2.4.8), and hence TBB would not be used. I'll try to post an example somewhere soon. Please let me know if I should mention any other config details.
2015-05-11 13:36:13 -0600	commented question	Does opencv_traincascades give consistent results over time? Yes, exactly same parameters, and samples every time. As far as I understood the process should have been non random, so I'm surprised myself.
2015-05-10 04:32:45 -0600	asked a question	Does opencv_traincascades give consistent results over time? Every time I run opencv_traincascades and then run detectMultiScale, in the results I get different number and quality of detected windows in test samples. I have tried on different machines and the results change almost every time. Is running opencv_traincascades not a deterministic process?
2014-04-25 08:49:45 -0600	commented question	Issues in Manual OpenCV4Android SDK setup Hey prometheus3k I switched to 2.4.8 and it worked. I also had to declare NDKROOT for all native projects. I'll wait for a more sensible answer for a few days and then close it out.
2014-04-24 09:37:32 -0600	asked a question	Issues in Manual OpenCV4Android SDK setup After the import step on this page: http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/O4A_SDK.html#import-opencv-library-and-samples-to-the-eclipse I keep getting the following errors like in a popup in Eclipse: Building workspace: Errors occurred during the build. Errors running builder 'Android Resource Manager' on project 'OpenCV Library - @OPENCV_VERSION@'. java.lang.NullPointerException Errors running builder 'Android Resource Manager' on project 'OpenCV Sample - 15 puzzle'. java.lang.NullPointerException Errors running builder 'Android Resource Manager' on project 'OpenCV Sample - camera-calibration'. java.lang.NullPointerException Cleaning all projects: Errors occurred during the build. Errors running builder 'Android Package Builder' on project 'OpenCV Library - @OPENCV_VERSION@'. Resource '/OpenCV Library - @OPENCV_VERSION@/bin' does not exist. Resource '/OpenCV Library - @OPENCV_VERSION@/bin' does not exist. I followed the warning and note given at the bottom as well, but that did help. My OpenCV4Android SDK version is 2.4.9.
2013-03-10 05:02:17 -0600	asked a question	Image not rendered correctly when rotated Hi, I'm new to OpenCV and was trying out the remap example given in the tutorials. I got unexpected results though, the normal image is rendered correctly but not the rotated one as show in the attached image. Please suggest what the problem could be and how I could solve it. I am running this on Ubuntu 12.10. Thanks, Abhishek
