Manager is used to provide apps with the best available version of Starting with 2.4.2 release for Android, OpenCV In this section we will explain how to make some existing project to If you encounter any error after thoroughly following these steps,įeel free to contact us via OpenCV4Androidįorum.

This tutorial also assumes you have OpenCV4Android SDK already If you need help with anything of the above, you may refer to tutorial_android_dev_intro guide. This tutorial assumes you have the following installed and With any other OS supported by OpenCV4Android SDK. This guide was written with Windows 7 in mind, though it should work This tutorial has been created to help you use OpenCV library within See also the last Fossies "Diffs" side-by-side code changes report for "dev_with_OCV_on_Android.markdown": 4.5.5_vs_4.6.0.
